Having an array instead of individual variables allows the use of the
replay_gain_mode enum as an array index.

Prefer C enums over CPP macros.

Renamed functions and variables.

No CamelCase file names.

"LOG_H" is a macro which is also used by ffmpeg/log.h.  This is
ffmpeg's fault, because short macros should be reserved for
applications, but since it's always a good idea to choose prefixed
macro names, even for applications, we are going to do that in MPD.

Get rid of CamelCase, and don't use a typedef, so we can
forward-declare it, and unclutter the include dependencies.

We want to expose the AudioFormat structure to plugins; remove some
clutter by moving its declaration to a separate header file.

it indented.
