snd_tlv_convert_from_dB: fix decreasing gain across entries
Currently, for a TLV consisting of TLV_DB_SCALE_ITEMs, if e.g. alsamixer
calls snd_mixer_selem_set_playback_dB() with a value that is in-between
two TLV_DB_SCALE_ITEMs, and xdir is negative, the selected raw hardware
value is the minimum in the first range above that value, rather than the
maximum in the last range below that value.
The user-visible symptom is that in alsamixer, pressing the down key to
reduce the value sticks at certain points, and cannot be incrementally
reduced any further, although directly selecting a much lower value (e.g.
by pressing 0..9) works as expected. This is triggered e.g. by
sound/soc/codec/max98090.c's max98090_hp_tlv[].
Fix this by checking whether xdir is positive or not, rather than
checking whether it has a non-zero value. The code to select the previous
range's max value is already present. This matches how xdir is used in
other parts of the code.

HDA-Intel: present up to 8 HDMI/DP outputs via "hdmi" device
Some new AMD cards have HDA codecs presenting 6 connected HDMI/DP pin
nodes (plus 1 unconnected pin node) according to the ALSA card database.
Example:
http://www.alsa-project.org/db/?f=

Bump the maximum number of presented HDMI outputs per card via the

Note that HDMI PCM devices DEV=4..7 use shared PCM device numbers, so
HDA cards that have over 4 audio PCM devices or multiple S/PDIF or modem

Fix doubly call of dlclose() in dlobj caching code
When multiple dlobj_cache items point to the same dlobj, dlclose() may
be called wrongly multiple times when these items are cleared, because
we manage the dlobj_cache list as a flat list. This results in a bad
segfault we've seen in openal-soft, for example.
For fixing this, we need the refcounting of dlobj itself. But, in
this case, we don't have to manage yet another list, since dlopen()
does a proper refcounting by itself. That is, we can just call always
dlopen() at each time a new function is assigned, and also call
dlclose() for each released dlobj_cache item at cleanup.

configure: do not detect incorrect cross-compiler
On Ubuntu 11.04, configuring with --build=x86_64-unknown-linux-gnu
--host=x86_64-linux-gnu finds a wrong cross-compiler:
checking for cross-compiler... x86_64-x86_64-pc-linux-gnu-gcc
This happens because of a dash vs underscore inconsistency in configure.in:
host=x86_64-pc-linux-gnu
host_cpu=x86_64
host_os=linux-gnu
which ${host_cpu}-${host_os}-gcc >/dev/null 2>&1 && echo ${host_cpu}-${host-os}-gcc

Instead of keeping modified asound.h and asequencer.h, copy the files

Some structs, unions and typedefs in asound.h and asequencer.h are
once renamed in local.h before inclusion, then renamed back again.
A bonus by this action is that some local codes don't have to refer to
sndrv_xxx any longer. However, some codes like src/seq/seq.c need
explicit cast because of unavoidable conflicts of struct types.

PCM: Avoid busy loop in snd_pcm_write_areas() with rate plugin
snd_pcm_write_areas() tries to wait until avail >= avail_min condition
is satisfied. This doesn't work always well when a rate plugin is in
the play.
When a partial data with a smaller size than a period is written, the
rate plugin doesn't transfer the data immediately to the slave PCM,
but kept in an internal buffer and it changes only the hwptr of the
plugin. Thus, the condition "avail < avail_min" is triggered for a
wait check although the underlying slave PCM has enough room. This
results in a call of snd_pcm_wait() which returns immediately after
poll() call, and the snd_pcm_write_areas() loop continues. As a
consequence, it falls into a CPU hog.
This patch fixes that busy loop by introducing a new fast_ops to check
the availability for wait of avail_min. Then a plugin can ask the
slave PCM whether the wait is required (or possible).
A few plugins like multi plugin need a special handling. Otherwise a
generic plugin function can be used.

pcm: fix 64-bit SNDRV_PCM_IOCTL_STATUS ABI breakage
Commit
cf40ea169aad (pcm: support for audio timestamps) added the new
audio_tstamp field to struct sndrv_pcm_status. However, struct timespec
requires 64-bit alignment, so the 64-bit compiler would insert
32 bits of padding before this field, which broke SNDRV_PCM_IOCTL_STATUS
with error messages like this:
kernel: unknown ioctl = 0x80984120
To solve this, insert the padding explicitly so that it can be taken
into account when calculating the ABI structure size.
