dB mappings do not work for controls not named "* Volume", since we do not
fall back to CTL_SINGLE in get_selem_ctl. Add that branch to make it
work.
Fixes dB ranges for e.g. controls named "* Gain".

snd_seq_set_input_buffer_size() has an assert() call with packet_size,
but it's still uninitialized at that point. Fix it with the real
packet size.

The recent rearrangement of header inclusion order caused a regression
showing segfaults on 32bit Arm. The primary reason is the
inconsistent compile condition depending on the inclusion of config.h;
while most of other code include pcm_local.h (that implicitly includes
config.h) at first, pcm_direct.c doesn't do it, hence the access with
direct plugins crashes.
For fixing it, we need to include config.h at the beginning. But,
it's better to include pcm_local.h for all relevant code for
consistency. The patch does it, and also it adds the guard in
pcm_local.h for double inclusions.

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.

Add a few new features for UMP 1.1:
- New attributes in UMP Endpoint and Block info
- Static block bit flag for EP info
Signed-off-by: Takashi Iwai <tiwai@suse.de>
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().
