mpdclient: moved code to filelist.c

Move everything which is solely filelist related to filelist.c and
filelist.h.  Fix the indentation of that file, and provide the struct
name "filelist".  Don't clear data in mpdclient_filelist_free() before
calling g_free().  Constify the "song" parameter to
mpdclient_filelist_find_song().
