Update: Utilize the debug mode, changing the error printing functions.

The `function` parameter is now replaced with `debug`.
There are several changes to the error printing functions to accommodate this.

A new function `fll_error_print_debug()` is added for handling the printing of this debug parameter.

Update the programs to ensure that they compile with these changes.
A follow up commit is required to fully and properly utilize this debug parameter.

The Featureless Make had to be updated further to get it to compile.
This fixes incorrect documentation that I observed.
The debug and function conversions are only enough to get things to compile.
This will still need a follow up commit to properly change everything.
