UMP SysEx messages have length field to specify the contained data
bytes, but they can be over the actual packet size. Add the proper
size limit checks for avoiding the access overflow.

Add the support to dump UMP 8-bit SysEx messages.
A slight code refactoring to share the code snippet between 7bit and
8bit SysEx handling, too.

Show the event prefix "SysEx" for UMP SysEx data. Otherwise it's
difficult to know what it is.

The printf format for a normalized velocity in MIDI2 mode had a typo,
resulting in a bogus value. Fix it.

Enhance aseqdump to interpret more UMP messages. Now it includes the
standard Stream messages and Flex Data messages.

A slightly better version. The extraction of a SysEx byte from a UMP
packet is more complicated than wished, in anyway.

config.h may contain defines like _FILE_OFFSET_BITS which influence
the system wide include files (off_t types, open -> open64 function
usage etc.).

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.

Correct the wrong value shown in MIDI2 default output (status instead
of channel). Also adjust the printf formats to use %2d consistently
for the channel numbers.

The outputs from UMP MIDI 1.0 are slightly differently shown as the
legacy MIDI 1.0 (the velocities and values are in hex), which is
rather confusing. Let's make them look more similar.

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.

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.
