* Fixed BACnet file object path name unintended path traversals by optionally restricting path name content with BACNET_FILE_PATH_RESTRICTED define.
* Added POSIX file path name checking for AtomicReadFile and AtomicWriteFile example applications. Prohibits use of relative and absolute file paths when BACNET_FILE_PATH_RESTRICTED is non-zero.
* 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
