aseqsend is a command-line utility which allows one to send SysEx

After UMP support was added in b399fb8 ev.type setting was inadvertently
dropped in the code path handling tempo meta event.
This is causing tempo meta events to not be handled at all.
Moreover, snd_seq_ev_set_fixed is also missing so MIDI files with
variable events such as SYSEX before the tempo meta event usually are
causing a segfault.

This patch adds to switch the operation mode of aseqdump to specify
how the values are shown. Namely, it allows to show the MIDI 2.0
values in two more different ways: compatible "normalized" view and
percentage view, in addition to the default "raw" view.
The "raw" view mode just shows the value found in the event almost as
is. The MIDI 2.0 values are shown in 16 or 32bit hex numbers.
The channel and UMP group numbers are 0-based, taking from 0 to 15.
OTOH, in the normalized view, the 16bit or 32bit velocity and data
values of MIDI 2.0 are normalized to the value fit in MIDI 1.0,
i.e. from 0 to 127, but with decimal points. Similarly, the pitch
wheel values are normalized between -8192 to 8191.
Also, the channel numbers and UMP group numbers are 1-based, taking
from 1 to 16.
In the percentage view, the velocity and data values are normalized
and shown in percentage, from 0% to 100%. The pitch wheel is
normalized from -100% to 100%. The channel and UMP groups are 1-based
as well as in normalized view mode.

The outputs from UMP MIDI 1.0 are slightly differently shown as the

This patch extends the aconnect program for supporting UMP.
Now the verbose output can show the UMP client version.
Also, a new option -a is added to control the behavior whether to show
the all ports including the inactive ports or not. As default, only
the active ports are shown, but UMP clients allow to hide some ports
as inactive.

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.

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.

rawmidi devices expose the card number via IOCTLs, which allows to
find the corresponding device in sysfs.
The sequencer provides no identifing data. Chromium works around this
issue by scanning rawmidi as well as sequencer devices and matching
them by using assumtions, how the kernel register sequencer devices.
This patch adds support for displaying the sound card number/PID to

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.
