- Removes MESSAGE_FORMAT_IS_CCSDS_VER2 and all references
- Now replaced by MISSION_MSGID_V2 and MISSION_INCLUDE_CCSDS_HEADER
  cmake variables
- Base MIDs localized to cpu1_msgids.h and improved documentation
  indicating example nature of implementation, note issue #732
  may make this obsolete
- Updated cfe_sb.dox for message module concept
- MsgId base type now always uint32 (reduces logic differences)
- Removed system log report of version used, in build and obvious
  from packet sizes
- Cleaned extra documentation from cfe_sb_msg_id_util.c
- Removed verification limits on CFE_PLATFORM_SB_MAX_MSG_IDS
- Removed UT_GetActualPktLenField and UT_GetActualCmdCodeField
  that depended on the define, shouldn't directly access message
  in a unit test since it's implementation dependent
- Default CCSDS version default now always 0 (per the standard)
  but mission configurable

Use OS_OpenCreate instead, which has an API consistent with the
rest of OSAL.  OS_open and OS_create will be deprecated.

This was using "DEFINED" to check if these variables were set.
Problem discovered is that this is always true because "SIMULATION"
is a cache var set from an environment variable, so it ALWAYS defined,
it is just empty if not being used.

Fix is to use if (SIMULATION) rather than if (DEFINED SIMULATION) which
should only be true if the string is not empty, as intended.

Fix #796, Remove dependency on CCSDS version define

Fix #906, Update variable checks in read_targetconfig

Fix #893, replace calls to OS_open and OS_creat

Fix #890, CFE_ES_CalculateCRC default stub behavior

Removed CFE_PLATFORM_CPU_ID, CFE_PLATFORM_CPU_NAME,
and CFE_MISSION_SPACECRAFT_ID.  Use CFE_PSP_GetProcessorId(),
CFE_PSP_GetProcessorName(), CFE_PSP_GetSpacecraftId().

Fix #827, Remove old name and id defines

Fix #900, Replace UT_Text with UtPrintf
