Update: improve status code handling, remove unnecessary code, and update status programs

The fl_status_is_fine(), fl_status_is_warning(), and fl_status_is_error() functions are no longer needed or valid with the current design around using error and warning bits.

The status conversion code should be more aware of digits.

Get rid of the "context" parameter in the status programs.
Redesign logic in the status programs to work with changes and function correctly (and consistently).
The status programs will eventually need to perform more extensive tests on parameters when digits or non-digits are required.
The current design only provides a very basic test on the first character of a given parameter.
