snd_seq_hw_get_client_info() calls mistakenly update_midi_version()
that leads to the update of seq->version from another client info.
It may lead to the inconsistent packet size calculation and the
unaligned read, eventually a program may hit segfault.
Drop the incorrect call of update_midi_version() for fixing it.

Align the behavior of rawmidi errors at open & co with PCM, i.e. use
SYSMSG() instead of SYSERR() for suppressing the error messages as
default.

In a couple places the function names were misspelled as "gruop"
instead of "group". Fix them.

Commit 2115cdb added a new call to the `SNDRV_PCM_IOCTL_SW_PARAMS`
ioctl on line 675 of src/pcm/pcm_hw.c, but passed the `sw_params`
argument by value; this should be passed by pointer.
I ran across this in the context of the direwolf software modem
for amateur radio; debugging details are in

Add a few new features for UMP 1.1:
- New attributes in UMP Endpoint and Block info
- Static block bit flag for EP info

This patch adds the basic support of UMP on ALSA sequencer API.
An extended event type, snd_seq_ump_event_t, is defined. It's
compatible with the existing type, snd_seq_event_t, but it has a
larger payload of 16 bytes instead of 12 bytes, for holding the full
128bit UMP packet.
The new snd_seq_ump_event_t must have the bit SND_SEQ_EVENT_UMP in the
event flags.
A few new API functions have been added such as
snd_seq_ump_event_output() and snd_seq_ump_event_input() for
reading/writing this new event object.
The support of UMP in the sequencer client is switched by the function
snd_seq_client_set_midi_version(). It can switch from the default
legacy MIDI to UMP MIDI 1.0 or 2.0 on the fly.
The automatic event conversion among UMP and legacy clients can be
suppressed via snd_seq_client_set_ump_conversion().
The inquiry of the associated UMP Endpoints and UMP Blocks can be done
via snd_seq_get_ump_endpoint_info() and snd_seq_get_ump_block_info().

Add a function to query the next available UMP device via control
interface, just like the existing one for rawmidi. As the UMP rawmidi
is compatible with the standard rawmidi, no extra helper for the
rawmidi_info is present. Ditto for the preferred subdevice, too.

This patch adds the initial support for UMP rawmidi access.
It's merely the wrapper for the standard rawmidi to access to the UMP

The silence size cannot exceed the silence threshold. Move the check
from the manual condition to the common code. This may happen for
small ring buffers (where the 1/10th second is too large).

The snd_pcm_wait() function is called also internally from
the various plugins to wait for the drain with -1 and from i/o
routines in pcm.c.
Define two special negative timeout values to distinguish the
drain and i/o wait and calculate the maximal timeout according
the wait place.

The application may not require to touch the playback
sample stream for the drain operation at all. In this case,
the application is responsible to setup a silencing mechanism
for the playback or another graceful stop (like using the
rewind operation).
