* Reduce default MS/TP APDU to 480 to avoid extended frames by default.
* Changed win32 port of localtime to use secure OS API functions when compiled with MSVC
* Changed all the sprintf to use snprintf instead in BSC tests to ensure null string endings.
* Fixed IPv6 handler to ignore original-broadcast when registered as a foreign-device
* Fixed IPv6 to leave multicast when registering as foreign device.
* Added reject in all confirmed service handlers, except GetEventInformation, when confirmed services with zero length occur which rejects with required parameters are missing message.
* Refactored errno use in service using debug_perror. Changed debug_perror usage to debug_fprintf.
* Updated file and function headers in basic/service modules.

* 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.
* 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.

* 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.

* 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’:
/bacnet-stack/ports/linux/dlmstp_linux.c:56:5: warning:

```
* 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:
warning: explicitly assigning value of variable of type 'int' to itself

* 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.

* Improved GCC compiler flags in ARM, OS, and test builds. Removed redundant flags, and made them consistent across various builds.
* Fixed redundant redeclaration of various functions detected by change in compiler flags.
* Fixed string truncation warning in bip-init detected by change in compiler flags.
* Fixed some set-but-not-used variables by creating dummy functions instead of using macros.
* Added dependent BACnet stack headers into bacdef.h file.
* Changed bacdef.h and other stack includes in c/h files to have a common pattern.
* Moved bits.h, bytes.h, and bacnet_stack_exports.h under bacnet/basic/sys/ folder.
* Added a MS/TP zero-config (automatically choose an unused MAC address) using an algorithm that starts with MAC=64 and waits for a random number of PFM (minimum of 8 plus modulo 64) before attempting to choose a MAC sequentially from 64..127. The confirmation uses a 128-bit UUID with the MSTP Test Request frame. The modifications are in src/bacnet/datalink/mstp.c and src/bacnet/datalink/dlmstp.c modules enabling any device to use zero-config if enabled. A working demonstration is in the ports/stm32f4xx for the NUCLEO board. Complete unit testing is included. Options include lurking forever (wait for a router or another master node before joining) or lurking for a minimum time (enables self forming automatic MAC addressing device nodes).
* Added MSTP extended frame transmit to bacnet/datalink/mstp.c and ports/stm32f4xx/dlmstp.c modules.
* Changed RS485_Send_Frame to MSTP_Send_Frame in mstp.c

* Fixes#346 by binding the broadcast socket to the port specific broadcast address rather than INADDR_ANY or INADDR_BROADCAST. Added additional compile and environment options for those who might need them.
* Changed the define USE_CLASSADDR to BACNET_IP_BROADCAST_USE_CLASSADDR to help manage namespaces.
* Added BACNET_IP_BROADCAST_BIND_ADDR environment variable to override the default broadcast binding address.
