Fix #385, Deprecate interrupt related APIs

[skliper]

Describe the contribution
Removes coverage test code completely. Marks OS_Int* API's as deprecated and implementations
removed if OSAL_OMIT_DEPRECATED defined
Fixes #385

Only changes under review for this request are 3618ae3, the rest of the commits were included to avoid merge conflicts (they were included in other pull requests for review)

Testing performed
Steps taken to test the contribution:

1. Remove calls from cfe/fsw/cfe-core/src/es/cfe_es_perf.c, note this change will break until the performance ticket is resolved (which removes the OS_Int calls) - CFE_ES_PerfLogAdd needs better mutual exclusion cFE#456
2. Built and ran test with and without OMIT_DEPRECATED defined.

Expected behavior changes
None

System(s) tested on

• Hardware: cFS Dev 3 VM
• OS: Ubuntu 18.04
• Versions: bundle, these commits, and changes noted above

Additional context

Note this would benefit from #362 being resolved. Also recommend testing for a vxworks and an rtems build. Also as mentioned needs nasa/cFE#456 resolved, and would benefit from the current integration candidate being merged (and rebase this on master)....

Rebased on current master

@skliper see conflict in merge dialog, I assume I should keep the #ifndef

<<<<<<< fix385-deprecate-os-int
#endif /* OSAL_OMIT_DEPRECATED */

=======
#ifndef OSAL_OMIT_DEPRECATED

Hard to tell without context, want me to rebase by branch on integration-candidate?

It should show you the context if you click resolve conflicts. Up to you though.

Either include them both or delete them both. Basically one commit deprecates all the interrupt APIs, the next deprecates all the shared memory. They can either be all in the same big ifndef block or two separate.
