1. Fix nasa#985, globalize "resource ID" definitions …

   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.

2. Fix nasa#1073, refactor SB API for proper global locks …

   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.
