Add a command line option to automatically exit after recording a fixed
number of MIDI events. This allows a program using arecordmidi to expect
a MIDI file to be written automatically when the specified number of
events have been received, instead of having to send a SIGINT or SIGTERM
programmatically.
It also avoids the need to have the arecordmidi process running in the
background, and then constantly stat the output file to check if any
bytes have been written to it (this makes for less predictable and
longer-running tests).
This functionality finds use in Chrome OS functional testing, since
having to send SIGTERM/SIGINT programmatically and then wait for the
output file adds unpredictability and delay to the tests.
The addition of this command-line option should (hopefully) not break
any existing usage.

The man page did not document what happens when multiple ports are
specified; this could be misinterpreted as the events being duplicated
so that they are played on all ports simultaneously. As suggested by
Peter Billam, clarify that these ports are only used for multi-port MIDI
files.

When throttling the data rate for big SysEx messages, use the bandwidth
that devices use in practice instead of the theoretical maximum.

By doing this we move them from the .data section to .rodata setion,
or from .data.rel to .data.rel.ro.
The .rodata section is mapped directly from the on-disk file, which is
always a save, while .data.rel.ro is mapped directly when using
prelink, which is a save in a lot of cases.

Make sure that the sequencer output buffer is big enough to handle all
events that we send, and split large SysEx commands into one-second
chunks so that the sequencer kernel code can handle them.
When listing ports with aplaymidi/arecordmidi, show only
ports that understand MIDI messages, i.e., that have the
SND_SEQ_PORT_TYPE_MIDI_GENERIC flag set.
This patch converts hyphens to minus signs in the man pages (for options,
emails, or command line examples).
This patch also closes one font modifier in iecset.1.
