21e0adfa3b aseqdump: Add dump of UMP Mixed Data Set messages
Add the support for yet more UMP messages.  UMP Mixed Data Set
messages are the generic data containers withe the message type 5
(shared with 8-bit SysEx).

095b064af6 aseqdump: Use snd_ump_get_byte() helper
For simplifying code, use the new helper function snd_ump_get_byte()
for extracting a byte data for SysEx and co.

0188f93f02 aseqdump: Correct the limit of UMP 7-bit SysEx bytes
UMP 7-bit SysEx can hold up to 6 bytes, not 14 bytes.

Fixes: 02b0c3af56 ("aseqdump: Avoid OOB access with broken SysEx UMP packets")

2185bc70a9 aplay: Print '=== PAUSE ===' only if it is supported
Instead of printing the '=== PAUSE ===' unconditionally before calling
do_pause(), move it to the function and only print it if the stream can
be paused.

If the stream cannot be paused that the '=== PAUSE ===' will be replaced
by `PAUSE command ignored (no hw support)` immediately, which is not
observable by users but automation scripts will catch the '=== PAUSE ==='
and might think that the stream is indeed got paused.

Move the print into do_pause() function after the snd_pcm_pause() have
returned without error to make sure it is only printed if the stream is
paused and we are waiting for the pause release from user to proceed.
