Updates the unit tests, unit test support, and
stubs to replace deprecated SB APIs with MSG APIs.

Update documentation to replace deprecated SB
APIs with MSG APIs

Update the core software from the deprecated SB
APIs to the MSG APIs.

Add an extra write of a null char which squelches a warning.

Do not enforce CFE_PLATFORM_ES_DEFAULT_STACK_SIZE as a minimum,
it should be a default.

The "osal_id_t" type isn't defined in any of the CFE message/interface
header files for use within telemetry.

This ID is an ephemeral runtime value and is not relevant to a ground
system or anything outside CFE, so it makes most sense to simply
remove this ID from the telemtry structure.  Note that all commands
are name-based, not ID-based, hence why this ID is not really useful.

The type of this should be CFE_ES_ResourceID_t, not uint32

Rather than directly referencing a constant, prefer to use
the sizeof() operator on the instance or type whenever possible.

Update use of uint32 to size_t in UT support code

Fix all use of uint32 for sizes, replace with size_t
Scrub all other types to make sure use is consistent,
using proper typedef whenever available.
