Add the "doxyfile" templates and various OSAL doxygen pages
locally under the "doc/src" directory.  Add a CMake script
to build the documentation in either a standalone or
integrated build environment.

Fix missing doxygen retvals

Note, other tests were OK, but depend on support being enabled and
supported by RTOS.  Script will report N/A items (due to no impl) as
missing.  Confirmed OS_HeapGetInfo OK on RTEMS.

For test cases where a function is invoked before OS_API_Init, only
check that the result is not success.  This will remain as "undocumented"
behavior - users should not call functions before init, because it is
not valid to do so.  A specific error code is not guaranteed here.

Note that the success case for OS_SetLocalTime is tested,
but is marked as a MIR test case because it requires
elevated permission, it is expected to fail when running
as a normal user on Linux.

In the stub generator script, filter only whole words
when ignoring keywords.  Do not match if the word appears
as a substring inside a larger word.

Truncate input lines at C++-style comment markers, in case users/projects
allow this style of comment.

Ensures correlation between the unit-tests and documented return
values for the OSAL binsem API.

Ensures correlation between the unit-tests and documented return
values for the OSAL common API.

Ensures correlation between the unit-tests and documented return
values for the OSAL countsem API.

Ensures correlation between the unit-tests and documented return
values for the OSAL directory API.

Ensures correlation between the unit-tests and documented return
values for the OSAL module API.

Adds documentation for OS_ERR_OUTPUT_TOO_LARGE and
OS_ERR_NAME_TOO_LONG.  These are primarily validated
via coverage test, as symbol table dump is only
possible on VxWorks.

Move the test for OS_INVALID_POINTER to after setup,
where the module ID is valid.

Ensures correlation between the unit-tests and documented return
values for the OSAL mutex API.

Ensures correlation between the unit-tests and documented return
values for the OSAL queue API.

Ensures correlation between the unit-tests and documented return
values for the OSAL task API.

Also adds the following test cases:
- Call OS_TaskCreate with a NULL stack pointer
- Confirm OS_TaskDeleteHandler function was invoked
- Confirm OS_TaskDelay interval

Ensures correlation between the test cases and documented return
values for the OSAL timebase API.

Ensures correlation between the test cases and documented return
values for the OSAL timer API.

Fix #961, update OSAL Config Guide link

The OSAL documentation should be standalone and not assume the
presence of cFE or directly link to its documentation.  This
corrects documentation link warnings.
