main,refactor: use LMAP_* enumerators when adding or removeing maps

The original code used a boolean value to toggle how filenames were
mapped to the parser by glob-like pattern or by extension.

To support the third way mapping a file name to a parser, by regular
expression pattern, we will use an enum value instead of Boolean.
