* fix BACDL_MSTP test on macOS
* remove old comments
The usleep() function takes microseconds, not milliseconds. So,
T_turnaround needs to be calculated in microseconds. If we don't do
this, at a baud rate of 9600, we end up waiting 4 microseconds instead
of 4 milliseconds, which goes against the rule.
* Changed ATmega168 example for ATmega328 on Arduino Uno R3 with DFR0259 RS485 shield. Added ADC interface from BDK port and mapped to some AV objects. Removed MS/TP MAC address DIP switch GPIO and moved MS/TP configuration to AV objects. Added AV units property. Added some Uno R3 Digital Inputs and outputs mapped to some BV. Added AVR EEPROM from BDK port and mapped some non-volatile data including MAC address and max manager and baud rate, device ID and names and description and location.
Depends on pcap (e.g. with Wireshark)
build with
#cmake .. -G"CodeBlocks - Unix Makefiles" -DBACDL_ETHERNET=ON -DBACDL_BIP=OFF -DBAC_ROUTING=OFF
run as normal user (not root) like Wireshark
* datalink/dlenv: Rename addr -> addr6 when ipv6
If we are building this file with BACDL_BIP6 and BACDL_BIP enabled we
get two definitions for addr. For this reason rename other addr6 so
there will be no conflict.
* config: Reorder MAX_APDU selection so biggest is first
When multiple datalinks are selected we should guess biggest MAX_APDU.
To do that we need to order selection based on biggest to lowest. With
this change MAX_APDU should be more correct most of the times and user
does not need to specifie that by hand.
* Make it possible to select multiple datalinks
Before we had option to select all datalinks. Many times you however do
not need all datalinks but just some. Change logic so that it does not
matter if user selects multiple datalinks. Now user just select what
they want and everything should just work.
* dlenv: Move variables start of function
Because we use C89 we need to move variables start of block.
* datalink: Hide strings.h because Windows
Windows does not support strings.h. Hide it from it.

* pre-commit: Update and enable clang-format check
There is newer version from clang-format so use that. We do not yet want
18 as that is little bit too new.
* Format some thing by hand which clang-format "breaks"
Clang-format will format some things little bit off in some cases.
Format some things by hand so we get cleaner end result.
* Run clang-format with
```
pre-commit run --all-files clang-format
```
We have already in previously checked places where clang-format does not
make good format and ignored those (hopefully most of the things).

* Make most of the functions const correct
Used clang-tidy and sonarlint to help find places where const could
pretty easily applied. Also lot of hand work.
This commit does not yet touch handlers and typedefs of those.
* Fix Arduino uno handler_who_is() has extra parenthesis
For some reason there is extra parenthesis. Remove it this is more
likely buildable.
* Bugfix/bacapp: Fix uninitilized array_index
We have changed bacapp_snprintf_value() to be const correct. After that
we got
```
/home/runner/work/bacnet-stack/bacnet-stack/src/bacnet/bacapp.c:3183:27: warning: 4th function call argument is an uninitialized value [core.CallAndMessage]
ret_val = bacapp_snprintf_weeklyschedule(
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 warning generated.
```
So analyzer could now spot that we do not actually initilize array_index
at all. Fix this by setting array_index to zero. Note that I actually do
not know if zeroing is right thing to do here. I choose zero as if this
has worked before it is most likely that it will work with zero value.
* cmake: Add and ignore Wwrite-strings compiler option
Wwrite-strings helps find places where const correctness is broken.
Example it will warn about these
```C
void func1(char* str);
func("test") /* "test" is const so we should not pass it to func1().
char* func2()
{
return "test"; /* func2() should return const char*.
}
```
We still need to ignore it as not all are fixed but let's add it already
so we remember that it should be opened at some point.

* Add editorconfig and pre-commit config
Editorconfig is widly used and supported file. It says basic things how
files should be formatted.
pre-commit is tool which can automatically check some basic checks like
code formatting everytime someone makes commit. This can also be used in
CI to run these things. Then it is very easy to do same things locally
as in CI. This also makes easy to select clang-format version so
everyone is using same one.
* clang-format: Ignore folders where are external code
We should not format external code. Add clang-format files to exclude
those. We should move external code always to example external/ folder
so we can exclude those more easily.
* clang-format: Remove custom zephyr/.clang-gormat
This clang-format file where introduces before our root clang-format. It
does not make sense anymore as we have root clang-format. Removing this
will unifie formatting in whole repo.
* clang-format: Add couple new rules
Add couple new formatting rules.
Always align const to left side. We did have only one place where it was
right side so this make sense as it is already rule for us.
I choose also insertbraces becuase when I run this I notice that we have
lot of multiline code without braces. So very error prone places. This
will take error possibility away. Repo also always use braces even with
single line statments so this does not matter much.
* ci: Add pre-commit validation
Validate pre-commit in CI.
* format: Convert spaces to tabs in Makefiles
Makefile normally use tabs. We enforce that with editorconfig. Fix
couple places where spaces where still in use.

It is lot easier to work with automatic formatters if we have external
files in different folder. For some tools we can example just exclude
external all together.

* format: Strip trailing whitespaces
We want to get rid of trailing whitespaces completly as they make just git
noice. Much better to start using automated tools to get rid of them once and
not getting them back again. This way git history will be cleaner and review
easier.
Commit was generated with:
pre-commit run --all-files trailing-whitespace
* format: Files should have exactly one new line end of them
It is good practice that every file has one new line. It is not now days so
mandatory but it also is not nice if file has lot of newlines end of it. We will
use pre-commit which takes automatically care about this so let's fix all.
Commit was generated with:
pre-commit run --all-files end-of-file-fixer
* format: Convert tabs to spaces
Project mostly use spaces over tabs. When mixing tabs and spaces this usually
makes formatting issues and also when changing those in commits it will make lot
of git noise. We will force spaces most of the time and use pre-commit to fix.
Commit was generated with:
pre-commit run --all-files remove-tabs

* clang-format: Ignore javascript files
Ignore javascript files. Clang-format is not very good formatter for
javascript files anyway. If we ever need javascript formatter we should
use Prettier.
* clang-format: Ignore some lines in sources
Couple things get formatted really funky if we let clang-format format
those. Just ignore those locally.
* zephyr/tescase.yaml: Fix yaml syntax
pre-commit hook check-yaml did found out that there are two skips.
Remove another as this is not right syntax.
* Fix repo contains unicode replacement chars
When running pre-commit text-unicode-replacement-char it founds that
there is couple unicode replacemnt chars. Remove and replace these.
* Convert some tabs to spaces manually
We will soon auto format tabs to spaces. How ever it could not do couple
thing so fix those by hand first.
* Make files with shebang executables
It is good habit that if file has shebang then it is marked executable.
These where found with pre-commit check-shebang-scripts-are-executable
checker.

* Fixed path of exports header in BSD ports.
* Fixed MacOS specific include in BSD ports.
* Fixed MacOS specific IOSSIOSPEED and IOSSDATALAT usage in BSD ports
* ci: Fix compile warning as errors was not correct
We want to enable warning as errors both Windows and Linux. This is
easiest to do with cmake option as -Werror does not work with MSVC. Also
it is self explaining what it does so no comment needed.
* dlmstp_linux: Fix -Wdeclaration-after-statement compiler warnings
Make dlmstp_linux C89/C90 combatible
```
/bacnet-stack/ports/linux/dlmstp_linux.c: In function ‘Timer_Silence’:

```
* Fix warnings produces by MSVC
Now that we have enabled /Wall for MSVC we get some warnings with it
which can be easily fixed.
We get following warnings:
```
src\bacnet\bacstr.c(223,39): warning C4127: conditional expression is constant
apps\router-mstp\main.c(1123,1): warning C4702: unreachable code
apps\epics\main.c(885,53): warning C4459: declaration of 'myState' hides global declaration
```
* cmake: Use /Wall with MSVC
Make MSVC to build cleanly with Wall. This might matter for some Windows
developers. And you never know if MSVC will find more bugs.
* cmake: Improve router build
Router build gives some warnings as it is not C90 compatible. It is ok
that example is not following C90 rules. Also it is annoing to new user
to build this cmake as first error usually is that libconfig is not
found. Let's just give warning about this so first build will usually go
smoother.

* linux/bip6: Use function over PRINTF macro
Our repo should be C89 compatibale. C89 does not support variac macros.
For this reason use variac functions. This also enables to print
different streams than just stderr.
Also now if something is changed in debug_fprintf it also affect here
which is good.
* Use __inline__ over inline in library
Use __inline__ over inline as that is C89/C90 combatible. With MSVC we
need to use __inline so just define __inline__ to it if not already.
* h_get_alarm_sum: Fix -Wself-assign compiler warning
We get Wself-assign if PRINT_ENABLED is 0
```
src/bacnet/basic/service/h_get_alarm_sum.c:129:16:

* bacint: Do not use ULL suffix
For sake of be more compatible with C89/C90 let's not use ULL at all.
Overall conversion functions are lot cleaner now. Only idiotic thing is
in bacnet_unsigned_length() where we need to do shift. There is probably
better way to do that but could not come up any at resonable time.
* Force C89/C90 and for tests C99
bacnet-stack seems to be all compatible with C89/C90. This is probably
design choice. Let's force this in CMake so no one will break that by
accident.
In tests we are using some C99 features already. Let's not be to strict
about those as those are "just tests".
* Fix -Wdeclaration-after-statement warnings
To make code C89/C90 compatible fix -Wdeclaration-after-statement
warnings.
We got like following warning without this change.
```C
bacnet-stack/apps/epics/main.c:293:5: warning: ISO C90 forbids mixed declarations and code [-Wdeclaration-after-statement
293 | uint32_t Object_Instance;
| ^~~~~~~~
```
* cmake: Add -Wno-c99-extensions compiler option
Clang does not like _Bool which is used in stdbool.h files. For now
let's just ignore this. We could define that differently but let's think
that another time. Now goal is to get warning free CI with more code to
be builded in there.
* cmake: Add -Wno-long-long compiler option for apple
Apple seems to do stupid things with their system header. There is
UINT64_MAX with ULL suffix and not like in Linux and Windows
__UINT64_C(18446744073709551615)
For this reason we need to ignore Wlong-long for it.

* Add and remove compiler warning compile options
Add some new compiler warnings. Some of those does not build clean so
ignore them for now. This also helps if some user use those options so
we ignore those for them also.
Also remove following ignores as they do not produce any warnings:
- Wno-attributes
- Wno-long-long
- Wno-implicit-fallthrough
* Fix -Wmissing-declarations compiler warnings
Fix new -Wmissing-declarations compiler warnings. I tried to look which
should be in headers and which should be static. Might be that some
statics should be in header as it is not easy to choose if something
should be exported or not.
* Fix -Wmissing-field-initializers compiler warnings
If we use { { 0 } } compiler thinks we might have mean that we only
meant initialize first member of struct or have forgotton to add second
one. We could do { { 0 }, 0 } but we can just do { 0 } which tells
compiler that hey just intialize this whole thing to zero.
* tests: Fix couple -Wfloat-conversion warnings
Add f prefix to floating point numbers to get some double to float
warnings away.
* ci: Make warnings as errors with cmake main build
To keep repo more clean from warnings use Werror flag when building main
project.
Windows should need -DCMAKE_C_FLAGS="/WX" but we have not ignore errors
for that yet so let's not yet take it in use.
* ci: Build also tests in matrix build
Enable also tests to be builded in our main matrix build. This way tests
will be builded also with clang and in future also with MSVC. We also
keep build very clean now as all warnings as catched.
With this we can also take out -Werror from compile_options as we add
that in CI. It is not good practice to keep that option always on. It
makes development lot harder. See example this blog post [1].

* Change MIT license texts to SPDX-License-Identifier
SPDX-License-Identifier is much easier to understand and grep than
license text so use that instead.
* Change GPL exception license texts to SPDX-License-Identifier
SPDX-License-Identifier is much easier to understand and grep than
license text so use that instead.
* Change misc license texts to SPDX-License-Identifier
There are some external code in repo which are not licenses as most of
the stuff in this repo. We still want every file to have SPDX identifier
to easily grep licenses.
* Add currently used license files
Even though Bacnet-Stack is using SPDX identifiers we still need to give
those license files with source. For this reason add all license files
to license/ folder.
SPDX has also files which would make same thing but this is style which
example Linux kernel is using and it is quite clear so I choose that one
for now.
I choosed not yet bring CC-PDDC as that is not right license for those
files.

* Updated the Makefile for mstpcap to accomodate macOS and to build the bacnet lib. Compiling working version of mstpcap on macOS 14, although compiling should work on many earlier versions. The --extcap-interfaces flag now works for macOS which allows one to use mstpcap as an extcap for Wireshark while listing the available serial ports and baud rates.
* note: Had to use uname to figure out if one is on Darwin/macOS vs vanilla BSD. From there, macOS specific supported features and location are used. For instance, the 76800 baud rate is natively supported.
* note: MacOS doesn't like placing the mstpcap executable in the global extcap plugin directory as it corrupts the Wireshark executable from an xattr and SIP (System Integrity Protection) perspective and macOS will refuse to run it calling it 'corrupt'. One could turn off xattr stuff, using xattr -cr, but could be risky long term. A safer, permissible workaround is to place the executable in the user .local extcap directory: '/Users/<your_user_name>/.local/lib/wireshark/extcap/'. If the directory doesn't exist just create it and copy the executable there.
* note: make the executable from the root or apps folder, as there are defines in the apps folder that are common to all the apps. The mstpcap executable is copied to bacnet-stack/bin/ folder.
