Is your feature request related to a problem? Please describe.
Many platforms support extra non-standardized features, but OSAL cannot make use of these. This includes items such as setting the processor affinity in a multi-processor system, or propagating the user-friendly task name at the OS level, as was suggested in #532.

Describe the solution you'd like
An event callback framework could help solve this problem, allowing those platform-specific features to be invoked from the PSP/BSP layer while keeping OSAL itself standards-compliant.

Describe alternatives you've considered
Use #ifdef conditional compiles for platform-specific features (ugly and not as maintainable).

Fix nasa#540, add OSAL event framework
e176459 
Define an interface to allow an app/PSP to be notified when state changes
or other events occur at the OS level.  Initially defined events are resource
creation/deletion and task startup.

The interface is easily extendable with more events as needed.

This can be used to add platform-specific/nonstandard functions by putting
the code inside the event handler at the PSP level.
