* Added dynamic RAM file system to use with basic bacnet file object.
* Added static RAM file system to use with basic bacnet file object.
* Added check for read-only during AtomicWriteFile service API for BACnet File object.
* Change stm32f4xx example to use static RAM file system.
* Fixed bacfile_count() function return type
* Changed BACnetARRAY index validation into ReadProperty, ReadPropertyMultiple, WriteProperty, and WritePropertyMultiple handlers.
* Changed the basic and example objects after refactoring BACnetARRAY index validation into ReadProperty, ReadPropertyMultiple, WriteProperty, and WritePropertyMultiple handlers.
* Added BACnet application decoder that understands that an array element of zero is an unsigned integer tagged value. Fixes RP and RPM apps when reading the array element zero of arrays.
* Added daylight savings time calculation module with unit testing.
* Added datetime daylight savings time and clock API
* Added basic datetime_local() clock using mstimer as basis and time-sync option. Integrated clock with ports/stm32f4xx example.
* 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.

* 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.

* Reduced MS/TP MAX_APDU to 480 from 1476 so that devices not use new MS/TP extended frame types which older routers do not understand.
* Added extra objects to STM32F4xx example to elicit edge cases in object-list for testing.
* Changed MS/TP master node self destination checks to be located in receive FSM
* Changed MSTP zero configuration: modified comments for state transition names; modified next station increment; refactored the UUID rand() to not be required by common zero config implementation; added more unit tests.
* Added another context to MS/TP user data to allow additional user data
* Added memap, avstack, and checkstackusage tools to STM32F4xx Makefile and CMake builds to calculate CSTACK depth and RAM usage
* Added memap, cstack, and ram-usage recipes to stm32f10x port Makefile. Added Cmake build.
* Removed local dlmstp.c module from stm32f10x port, and used the common datalink dlmstp.c module with MS/TP extended frames and zero-config support.
* Added .nm and .su to .gitignore to skip the analysis file residue.
* 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).
* Fix device object ReinitializeDevice service handling examples of no-password in the device. Add unit testing of device object ReinitializeDevice service. Add API for setting ReinitializeDevice device object password.
* Fix DeviceCommunicationControl service handling example of no-password in the device.
