Fixed memory/status recovery when error occured in MIDI_mciOpen. 

Fixed support for RMID files in MIDI_mciOpen.
Fixed bug for playing MIDI files with tempo changes. Sound output is
now correct, but length of tracks (and therefore of whole file) is not
correct.
Changed error values (INTERNAL => INVALID_FILE) when file cannot be read.
