alsa-lib: heavy pcm atomics cleanup
The following patch comes from the realization that at least ARM code
for atomics is quite broken and nobody has cared for a decade.
A quick dive shows that only snd_atomic_{read,write}_{begin,end}
appear to be used widely. These are implemented using wmb/rmb.
Only other use of atomic functions is in pcm_meter.c.
The #SND_PCM_TYPE_METER plugin type appears rarely, if ever, used.
I presume these days anyone who wants a meter/scope will do in pulseaudio
layer instead of alsa.
It would seem better fit to have pcm_meter in alsa-plugins instead
of alsa-lib, but I guess that would be an ABI break...
So instead, I'm proposing here
1. Removal of all hand-crafted atomics from iatomic.h apart from barriers,
which are used in snd_atomic_{read,write}_{begin,end}.
2. Using __sync_synchronize as the default fallback for barriers. This
has been available since gcc 4.1, so it shouldn't be a problem.
3. Defining the few atomics used by pcm_meter.c withing pcm_meter.c
itself, using gcc atomic builtins[1].
4. Since gcc atomic builtins are available only since gcc 4.7, add a check for
that in gcc configure.in, and don't build pcm meter plugin if using
older gcc.
The last point has the impact, that if there actually is someone who 1)
uses the meter plugin 2) wants to upgrade to 2014 alsa-lib 3) but
does not want to use a 2012+ gcc - that someone will be inconvenienced.
Finally remove the unneeded configure check for cpu type. We can
trust the gcc to set right flags for us.

pcm: Add thread-safety to PCM API
Traditionally, many of ALSA library functions are supposed to be
thread-unsafe, and applications are required to take care of thread
safety by themselves. However, people never be careful enough, and
almost all applications fail in this regard.
This patch is an attempt to harden the thread safety in exported PCM
functions in a simplistic way: just wrap some of exported functions
with the pthread mutex of each PCM object. Not all API functions are
wrapped by the mutex since it doesn't make sense. Instead, the
patchset covers only the functions that may be likely called
concurrently. The supposedly thread-safe API functions are marked in
the document.
For achieving the feature, two new fields are added snd_pcm_t when the
option is enabled: thread_safe and lock. The former indicates that
the plugin is thread-safe that doesn't need this workaround and the
latter is the pthread mutex. Currently only hw plugin have
thread_safe=1. So, the most of real-time sensitive apps won't be
influenced by this patchset.
Although the patch covers most of PCM ops, a few snd_pcm_fast_ops are
left without the extra mutex locking: namely, the ones that may have
blocking behavior, i.e. resume, drain, readi, writei, readn and
writen. These are supposed to handle own locking in the callbacks.
Also, if anyone wants to disable this new thread-safe API feature, it
can be still turned off via --disable-thread-safety configure option.
