Cleanup: Append "_e" to all enums, update status types, and update status strings.

Cleanup: Append "_e" to all enums, update status types, and update status strings.

A new practice is to have "_e" at the end of all enums.
Update all of the existing enums to follow this practice.

I noticed some fixme comments about moving the status codes to a lower level.
Do this.
Update all code accordingly.

The status code strings are only for special cases, so make this its own project directory (for both Status and FSS Status).
These are f_status_string and fll_fss_status_string.
