- One return point
- Eliminates "possible uninitialized variable" static
analysis warning

Divide the "position" (in bytes) by the size of the event IDs
to get the number of events.

Also correct bad event checks in TBL UT.

Move certain definitions related to the CFE_ES_ResourceID_t type
into the global CFE include files.  This introduces two new headers:

cfe_resourceid.h (public)
cfe_resourceid_internal.h (private to CFE core apps)

This allows other CFE core apps, such as SB, to use the
CFE_ES_ResourceID_t using the same manipulators.

Significant refactor of many SB API calls to address inconsistencies
with respect to locking and unlocking of global data structures.

First this updates the definition of CFE_SB_PipeId_t to use the
CFE_ES_ResourceID_t base type, and a new ID range.  Notably this
prevents direct access to the CFE_SB.PipeTbl global, forcing
code to go through the proper lookup routine, which should only
be done while locked.

All API implementations follow the same general pattern:

- Initial checks/queries while unlocked
- Lock SB global
- Lookups and/or modifications to the pipe table/routing info
- Unlock SB global
- Invoke other subsystems (e.g. OSAL)
- Re-lock SB global (if needed) do final update, and unlock again
- Send all events

All error counters should be updated at the end, while still locked.
All event processing is deferred to the end of each function, after
all other processing is done.

Define a data structure in cfe_sb_msg.h that will be used
with the "write pipe info" command (CFE_SB_SEND_PIPE_INFO_CC).

This allows the internal CFE_SB_PipeD_t descriptor object to
evolve as needed without affecting the binary format of the
file that is generated form this command, and items such
as memory pointers may be excluded from the file.
