So far, aplaymidi2 passes the MIDI1/MIDI2 channel voice UMP messages
to the target while processing other UMP messages internally.  But
sometimes we'd like to pass all UMP messages as is and let the
receiver processes.

This patch adds a new option -a (or --passall) to pass the all UMP
packets included in the given MIDI Clip file to the target as-is.
