* Refactored BACnetShedLevel encoding, decoding, and printing into separate file. Added unit testing.
* Added API to load control object for shed-level, start-time, duty-window, full-duty-baseline, and enable.
* Fixed bacapp sprintf for shed level and host-n-port found in scan build.
* Refactored the BACnet/SC datalink initialization order by moving certificate file checks and hub connection registration to occur after datalink initialization
* Replaced stdlib rand() with platform-specific cryptographically secure random functions (RtlGenRandom for Windows, getrandom for Linux, arc4random_buf for BSD) to generate UUID and VMAC addresses, preventing duplicates that broke connections
* Enabled conditional debug output in BACnet/SC components when BUILD=debug is specified
* Added basic timer object, internal state machine, and unit tests
* Added BACnetTimerStateChangeValue encode, decode, parse, print, and diff with unit tests
* Changed handler of add/remove list element to check if the property is a BACnetLIST
* Added BACnetLIST utility for handling WriteProperty to a list.
* Fixed outlier ReadProperty object handlers to return zero when the RP parameter is NULL.
* Fixed compiler warning format '%u' expects argument of type 'unsigned int', but argument 4 has type 'uint32_t' {aka 'long unsigned int'} [-Werror=format=] by casting or increasing format specifier size and casting. Increased the size of the name string to handle larger possible integers.
* Fixed copied code that no longer needs static function scope variables for text names.
* Added missing API defined in header into ports/win32/dlmstp.c module, added a PDU queue and refactored receive thread, and refactored MS/TP timing parameters.
* Added missing API defined in header into ports/linux/dlmstp.c module, and refactored MS/TP timing parameters.
* Added missing API defined in header into ports/bsd/dlmstp.c module, and refactored MS/TP timing parameters.
* 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 WriteProperty error code for PROP_FD_BBMD_ADDRESS and PROP_FD_SUBSCRIPTION_LIFETIME properties.
* Fixed dead-code warning after enabling all datalinks for basic network port object using the property list as the R/W checking for the port type.
* 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.
* Changed NDPU priority on confirmed messages to use requested NDPU priority.
* Renamed debug_aprintf to debug_printf_stdout for clarity.
* Convert most debug_fprintf usage to debug_print to reduce text bloat in AVR build
* Refactored lighting command operations from the lighting output object, and added unit testing. Integrated the result back into lighting-output object.
* 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.

* 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

* 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:
ISO C90 forbids mixed declarations and code [-Wdeclaration-after-statement]
56 | int32_t res;

/bacnet-stack/ports/linux/dlmstp_linux.c: In function ‘dlmstp_init’:
/bacnet-stack/ports/linux/dlmstp_linux.c:795:5: warning:

795 | struct termios newtio;
| ^~~~~~
```
* 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.

* 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.
