            sbc: better compatibility with ARM thumb/thumb2

            ARM assembly optimizations fail to compile in thumb mode, but are fine
            for thumb2. Update ifdefs in the code to make use of ARM assembly only
            when it is safe and also make sure that no optimizations are missed
            when compiling for thumb2.

            The problem was reported by Paul Menzel:
            https://tango.0pointer.de/pipermail/pulseaudio-discuss/2011-February/009022.html

This patch is tested with OpenEmbedded using `minimal-uclibc` for `MACHINE = "at91sam9260ek"`.

Note that changes to ipc.h from 8f3ef04b had to be manually reapplied.

daemon: Fix regression introduced in f1d1447e.

With Tanu's patch, the server no longer starts when a server is configured.
While this is sensible in most circumstances there is a corner case where
we still want to start.

In a typical X11 login, module-x11-publish will be loaded and will thus
set the PULSE_SERVER X11 property on the root window. This then hits the
check introduced in f1d1447e and exits. If PA had previously crashed
(thus leaving behind it's X11 properties) then this means that we will not
autospawn nor even allow ourselves to be started manually until
pax11publish -r is run to clear out the X11 properties. This is obviously
not desirable.

This patch introduces a more in-depth check of the server. If it looks like
a local unix domain socket, then we do not exit straight away and instead
probe further. This should not pose any problems with e.g. remote SSH
usage as the DBus Machine ID is used in the server string.

sbc: added "cc" to the clobber list of mmx inline assembly

In the case of scale factors calculation optimizations, the inline
assembly code has instructions which update flags register, but
"cc" was not mentioned in the clobber list. When optimizing code,
gcc theoretically is allowed to do a comparison before the inline
assembly block, and a conditional branch after it which would lead
to a problem if the flags register gets clobbered. While this is
apparently not happening in practice with the current versions of
gcc, the clobber list needs to be corrected.

Regarding the other inline assembly blocks. While most likely it
is actually unnecessary based on quick review, "cc" is also added
there to the clobber list because it should have no impact on
performance in practice. It's kind of cargo cult, but relieves
us from the need to track the potential updates of flags register
in all these places.

sbc: new 'sbc_calc_scalefactors_j' function added to sbc primitives

The code for scale factors calculation with joint stereo support has
been moved to a separate function. It can get platform-specific
SIMD optimizations later for best possible performance.

But even this change in C code improves performance because of the
use of __builtin_clz() instead of loops similar to what was done
to sbc_calc_scalefactors earlier. Also technically it does loop
unrolling by processing two channels at once, which might be either
good or bad for performance (if the registers pressure is increased
and more data is spilled to memory). But the benchmark from 32-bit

above 0dB (aka 100%) for very quiet audio sources.

We recommend that a comprehensive volume control UI should allow
users to set volumes up to this limit, although of course should
deal gracefully if the user has set the volume even higher than this
without resulting in a feedback loop that effectively limits the
upper volume.

The value chosen is +11dB. This was selected somewhat subjectively
and is very similar to the current 150% that gnome-volume-control
uses (which is ~+10.57dB).

On the plus side, we now recommend that everyone allows
'Volumes up to 11' which is pretty awesome.
