7d9972c6ad Allow hint for ctl, hwdep, timer and seq
Like pcm and rawmidi, each object parser needs to accept the hint
component.  Now a new local function _snd_conf_generic_id() was
introduced to replace each call of "comment" and "type" field checks.

Also, the two existing identical functions for pcm and rawmidi are
removed and the new function is used commonly.

85e4704151 pcm: Provide a CLOCK_MONOTONIC_RAW timestamp type
For applications which need to synchronise with external timebases such
as broadcast TV applications the kernel monotonic time is not optimal as
it includes adjustments from NTP and so may still include discontinuities
due to that. A raw monotonic time which does not include any adjustments
is available in the kernel from getrawmonotonic() so provide userspace with
a new timestamp type SNDRV_PCM_TSTAMP_TYPE_MONOTONIC_RAW which provides
timestamps based on this as an option.

326c6802e4 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.

9b5beef1dd Merge kernel uapi/sound/asound.h and asequencer.h
Instead of keeping modified asound.h and asequencer.h, copy the files
in the kernel include/uapi/sound as is, and give some renames for
avoiding conflicts with alsa-lib's definitions.

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.

Another significant change is that now snd_pcm_sw_params.period_event
field is removed.  Instead, try to access the last reserved field
internally.

2b49df0c55 pcm: fix 64-bit SNDRV_PCM_IOCTL_STATUS ABI breakage
Commit cf40ea169a (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.
