The CFE_SB_GetMsgId/SetMsgId functions, among others, were implemented as replicas of the actual FSW code. This creates a dependency on the actual definition of MsgId used by the mission. This makes the stub and actual stub. Stubs not actually read/write to the message in any way, they just manipulate a local (stored in the UT framework) out-of-band buffer to hold the metadata about the message. This revealed a few other minor issues in test cases where they were depending on values sitting in globals (fixed).

@jphickey does this necessitate an update to the sample_app unit tests? Looks like SAMPLE_ReportHousekeeping test is failing. |

For CFE_SB_SendMsg this was still reading the length directly from the header. It needs to use the metadata value instead.

Found the issue, see commit 6f06b16, the CFE_SB_SendMsg() stub needs to read the length from the metadata. Pushed directly to IC as hotfix. |

Describe the contribution
This makes the SB stubs which access message structures into actual stubs, not a replica of the normal implementation. Stubs manipulate a local (stored in the UT framework) out-of-band buffer to hold the metadata about the message.
This removes the dependency on the actual definition of MsgId used by the mission and makes them agnostic to the setting of extended headers.
This revealed a few other minor issues in test cases where they were depending on values sitting in globals (also fixed).
Fixes #618
Testing performed
Build unit tests with SIMULATION=native ENABLE_UNIT_TESTS=TRUE with and without configuration for extended headers. Confirm passing.
Expected behavior changes
Unit tests now build and run when
MESSAGE_FORMAT_IS_CCSDS_VER_2is configured.System(s) tested on
Ubuntu 20.04 LTS 64 bit
