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.

For some special plugin combos (rate+softvol+hw for example), the same
areas with same offsets can be asked to be copied (softvol). The collapse
check uses own areas created on heap, causing dst_area == src_area &&
dst_offset == src_offset check bypassed.

Add workaround for conflicting IEC958 controls for HD-audio
When both an SPDIF and an HDMI output are present on HD-audio, both
try to access IEC958 controls with index=0 although one of them must

In this patch, the corresponding support is added in alsa-lib side.
The new "skip_rest" boolean flag is added to the hooked element
definition which indicates that the rest of element array will be

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.

pcm: support for audio timestamps
add new snd_pcm_status_get_audio_htstamp() routine to
query the audio timestamps provided by the kernel.
This change provides applications with better ways
to track elapsed time. Before this patch, applications
would subtract queued samples (delay) from written samples,
resulting in a 1-2 sample error.
Also add snd_pcm_hw_params_supports_audio_wallclock_ts()

PCM: plug: Move fast_ops copy after slave configuration.
This is an OpenPGP/MIME signed message (RFC 2440 and 3156)
The plug plugin copies the fast_ops structure and fast_op_arg from its
slave PCM on initialization and after inserting a new plugin. This works
unless the slave PCM is also an instance of the plug plugin because plug
can change its fast_ops structure during _snd_pcm_hw_params.
Instead of copying fast_ops in snd_pcm_plug_insert_plugins wait until
the end of snd_pcm_plug_hw_params when the slave has been fully
initialized.
This fixes a crash when two instances of plug are instantiated back to
back and the format conversion plugin inserted by the second is skipped
by the first because the fast_ops pointer is not properly updated.
