PCM and control shm plugins and aserver have some codes to resolve the
host address and check whether it's a local host although the given
address is never used. In addition, the code contains gethostbyname()
that is known to be obsoleted. So, let's get rid of all these unused
codes.
The host configuration item is still accepted (but just ignored) for
keeping the compatibility.

with cset command, UCM set kcontrol parameters directly:
cset "name='<KCONTROL_NAME>' 1<,2,3,...>"
This patch enables UCM to set kcontrol with parameters from
configure file:
cset-bin-file "name='<KCONTROL_NAME>' <path/to/file>"
where "cset-bin-file" is a newly added keyword alongside of "cset",
to indicate cset with binary data in file.
The binary data in file is parameter for audio DSPs, and it's just
passed by UCM/ALSA as raw data. The data type of parameter elements
must be byte, and the count must matches driver definition.

a combination of some of the following garbage collecting LD/CFLAGS

-fno-unwind-tables -fno-asynchronous-unwind-tables
causes the symbol versioning marker symbols to be removed from BSS
since they're otherwise unreferenced. this causes dlsym failing to
find them which results in runtime breakage:
$ alsamixer

ALSA lib conf.c:3328:(snd_config_hooks_call) symbol snd_config_hook_load is not defined inside (null)
ALSA lib conf.c:3788:(snd_config_update_r) hooks failed, removing configuration

since alsa was built with --without-versioning, doing those versioning

When a slave PCM gets an error like XRUN, it stops and notifies with
SND_TIMER_EVENT_MSTOP event. But the current code filters out this
type and eventually hang due to the empty timer queue. The fix is to
just add this event type to the filter bit mask.

The current behavior of snd_pcm_rewindable and snd_pcm_forwardable means
that the returned value is only accurate to one period. Or maybe even
meaningless if period interrupts are off. Fetch the up-to-date position
of the hardware pointer, as that's what is wanted by callers.

Such negative returns are possible during an underrun if xrun detection
is disabled.
So, don't store the result in an unsigned variable (where it will
overflow), and postpone the trigger in such case, too.

Such negative values can happen when an underrun happens and xrun
detection is disabled. Another situation is if the device updated the
pointer before alsa-lib has a chance to detect the xrun.
The problem is that these negative values could propagate to the
snd_pcm_rewindable return value, where it is specified that negative
returns must be interpreted as error codes and not as negative amount of
samples.

There are a few places where the argument of the .rewind or .forward
callback is checked against the same value as returned by .rewindable or
.forwardable. Express this "don't rewind more than rewindable" logic
explicitly, so that the future fixes to the rewindable size can go to
one function instead of two.
While at it, take advantage of the fact that snd_pcm_mmap_avail() cannot
return negative values (except due to integer overflow, which is AFAICS
impossible given the current boundary choice).

This function returned incorrect results when hw.ptr was near the

The result was incorrect, because it was used as a return value of
various *_rewindable() functions and also as the delay for ioplug.

The PCM route plugin can assign the destination value from average of
multiple sources with attenuation. This requires the read of each
channel value, sums and writes the resultant value in the requested
format.
Currently, get_labels is used for reading source values while
put32_labels is used for writing the dest value. This is, however,
a buggy implementation; get_labels gives the value as is only with
endianness and signedness conversions, but put32_labels assumes that
the value is normalized to 32bit int and it shifts down to the dest
format. In addition, the current code lacks get_labels entries for
the 24bit formats, as Shengjiu Wang spotted out.
For fixing these bugs, this patch replaces the read with
get32_labels and use always 64bit int for sum. This simplifies the
code a lot and drops many lines.
