aseqdump: Add UMP support

Browse source 
Add the support for showing the UMP events to aseqdump.
With the new option -u, the program can start as a UMP sequencer
client and receive UMP events instead of the legacy MIDI events.

Also, the automatic event conversion among legacy and UMP clients can
be suppressed by the new -r option, too.
