Currently the TLV topology structure is targeted at only supporting the
DB scale data. This patch extends support for the other TLV types so they
can be easily added at a later stage.
TLV structure is moved to common topology control header since it's a
common field for controls and can be processed in a general way.
Users must set a proper access flag for a control since it's used to decide
if the TLV field is valid and if a TLV callback is needed.
Removed the following fields from topology TLV struct:
- size/count: type can decide the size.
- numid: not needed to initialize TLV for kcontrol.
- data: replaced by the type specific struct.
Added TLV structure to generic control header and removed TLV structure from
mixer control.

We copied include/list.h from Linux kernel, and it's of course in
GPLv2. This has raised concerns to many people, as it's not clear
whether such a code is considered to be completely trivial, thus it
might be seen as a derivative work, which takes effect in GPL, as
suggested by Clemens.
For clearing the situation, this patch replaces the existing list.h
implementation from a new version. The API is kept to be compatible,
but the codes were written from full scratch under LGPL, to be aligned
with other alsa-lib codes.

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.

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.
