[Issue 1136] Fix for race condition in JBM allocate/free data unit (!1689) · Merge requests · IVAS Codec Public Collaboration / IVAS Codec

Fix for Issue 1136 - Potential race condition in JBM in Data Unit Alloc/Free

Introduce a mutex encapsulation supporting windows and posix systems
Raise error if non posix, non windows platforms
Use mutex to prevent race condition around update to the shared variables (h->freeMemorySlots and h->nFreeMemorySlots)
Fix should be available for all posix systems including unix, linux, android, macos, ios
For bare-metal/non posix/non windows compilers, currently error is thrown in build
It can be stubbed for custom implementation if needed
