* Added WriteProperty handler in the Structured View object with handling for object-name, description, node-subtype, node-type, default-subordinate-relationship, represents, subordinate-list, subordinate-annotations, subordinate-node-types, and subordinate-relationships in the basic Structured View object.
* Changed Structured View character strings for object-name, description, and node-subtype to use dynamic strings to support WriteProperty.
* Added characterstring_utf8_valid(), characterstring_utf8_strdup() and write_property_characterstring_utf8_strdup() for UTF-8 string duplication.
* Added write property tests for array handling and validation of array index values
* Added backup failure timeout functionality and related methods in device management
* Fixed STARTBACKUP to hold at PERFORMING_A_BACKUP per spec, not IDLE.
* Added error handling for reinitialization during restore process to prevent accidental delete of all objects.
* Added some missing Create/Delete object functions. Formatting.
* Fixed Program object type in bacnet_device.c module.
* Added CreateObject and DeleteObject for basic Octet String Value and Positive Integer Value objects.
* Changed PositiveInteger present-value datatype to BACNET_UNSIGNED_INTEGER.
* Added callback API for extending the basic Device object and children with proprietary properties for ReadProperty and WriteProperty services. The callback API includes a function to get the specific proprietary property list for any specific object instance in the device, functions to handle the ReadProperty or WriteProperty of the proprietary property.
* Added a new property_list_function typedef to proplist.h for proprietary property list callbacks
* Removed the object-specific proprietary property implementation from the Loop object
* Added test coverage in the Device test validating the proprietary property API usage
* Added example Device object and property value backup using create-object list-of-initial-values and writable properties. Initiated using ReinitializeDevice with STARTBACKUP command. Added backup and restore required properties to the Device object.
* Fixed fwrite parameters in bacfile_posix_write_stream_data to return the correct number of bytes written.
* Added Device Management-Backup and Restore-B (DM-BR-B) conversion to Wireshark PCAP format command line utility in apps/dmbrcap which decodes and provides a view of the binary backup file.
Added a new API for writable property lists across all the basic example object types, preparing for the introduction of a Writable_Property_List property in every object in a future BACnet standard revision.
The lists can be used by backup and restore feature to automatically choose the object property values in the backup that can be restored via internal WriteProperty directly from BACnet CreateObject services with List of Initial Values.
Updated existing device object examples to include these writable property lists.
Fixes the CreateObject service list-of-initial-values encoding and decoding by refactoring the data structure to be similar to WriteProperty. The implementation changes from using a linked list of property values to using a flat buffer approach with delayed decoding.
Changes:
* Refactored BACNET_CREATE_OBJECT_DATA structure to use an application_data buffer instead of a linked list for initial values
* Added a new create_object_process() and create_object_initializer_list_process() functions to centralize object creation logic and error reporting
* Updated all device implementations to use the new centralized creation functions
* Enhanced the create-object example application to support command-line specification of initial property values
* Added comprehensive test coverage for the new encoding/decoding and processing functions
* Added ListElement service callback for storing data.
* Added Audit Log and Time Value objects to basic device.
* Added Audit Log object to Makefile and CMake builds.
* 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.
* Added Device_Object_Functions_Find() API to enable override of basic object API function.
* Added Device_Object_Functions() API to return basic object API table of functions for all objects.
* Converted device object test to use common read-write property test. Extended the basic BACnet device object example API.
* Created BACnet/IP and COV test mocks to enable device object testing with less dependencies.
