Neither module should depend on the other, so move shared functions to their
own file for this purpose, and ensure source files are compiled only when the
required modules are enabled.

dolby_e.c/h - Decoder only functions, tables and structures.
dolby_e_parser.c - Parser only functions, tables and structures.
dolby_e_parse.c/h - Shared functions, tables and structures.

Probably OK idea, but wait maybe for others few hours.
