aplaymidi: Add UMP support
By switching via the new option -u, aplaymidi can behave as a UMP client and output UMP packets instead of legacy sequencer events. As of now, the only supported version is 1. Signed-off-by: Takashi Iwai <tiwai@suse.de>

Changes the sequencer client to the given MIDI version and outputs via

the UMP packets instead of legacy sequencer events.

As of now, the only supported version is 1.
|

|

A client can be specified by its number, its name, or a prefix of its
|
||||
name. A port is specified by its number; for port 0 of a client, the
|
||||
":0" part of the port specification can be omitted.
