* 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].

* getevent: Deprecate getevent_encode_apdu()
Steve suggested that we should deprecate getevent_encode_apdu() [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.

* Refactored and secured BACnetActionCommand codec into bacaction.c module for command object and added to bacapp module encode/decode with define for enabling and pseudo application tag for internal use.
* Simplified bacapp_data_len() and moved into bacdcode module as bacnet_enclosed_data_len() function.
* Secured ReadProperty-REQUEST and -ACK decoding.
* Removed deprecated Keylist_Key() functions from usage.
* Removed pseudo application datatypes from bacapp_data_decode() which only uses primitive application tag encoded values.
* Defined INT_MAX when it is not already defined by compiler or libc.
* Deprecated bacapp_decode_application_data_len() and bacapp_decode_context_data_len() as they are no longer used in any code in the library.
* Added BACnetScale to bacapp module. Improved complex property value decoding. Refactored bacapp_decode_known_property() function.
* Refactored and improved the bacapp_snprintf() function for printing EPICS.
* Fixed Lighting Output WriteProperty to handle known property decoding.
* Added Zephyr settings subsys to enable storing of BACnet values according to BACnet object property value path.
* Added BACnet Basic features to enable basic samples. Refactored the zephyr BACnet profile B-SS sample to use BACnet basic subsys.
