* 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.
* 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
* Refactored ports/xplained to use common DLMSTP module to enable extended frames
* Added floating point compares in cases where they don't exist in math library
