Fix nasa#762, scrub of all CFE UT stub functions

Scrubs all CFE unit test functions to ensure that:

1. All functions in the CFE public API have a stub function implemented
2. All parameters to the stub function are registered in the context object,
   so the values will be available to hook functions.
3. The names of all parameters match the prototype/documentation, so hook
   functions that use name-based argument value retrieval will work.
