This is pretty cosmetic change; there's no actual functionality added.
Previously the volume_writable information was available through the
pa_sink_input_is_volume_writable() function, but I find it cleaner to have a
real variable.
The sink input introspection variable name was also changed from
read_only_volume to volume_writable for consistency.

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.

On 64-bit systems LONG_MAX is greater than the largest possible value of a

always false. On 32-bit systems pa_atou() can return a value that will overflow

necessary.

daemon: Fix regression introduced in

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.

The second process: daemon_pipe[1] is not closed if anything fails
between the first and the second fork() call. Also, if the second fork
fails, then the finish section writes to daemon_pipe2[1], even though
only the third process should do that. Also, if anything fails between
the first and the second fork, then the second process never writes
anything to daemon_pipe[1]. I don't know what happens in the first
process in this case - does it get an error or does pa_loop_read() get
stuck.

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: faster 'sbc_calculate_bits' function
By using SBC_ALWAYS_INLINE trick, the implementation of 'sbc_calculate_bits'
function is split into two branches, each having 'subband' variable value
known at compile time. It helps the compiler to generate more optimal code
by saving at least one extra register, and also provides more obvious
opportunities for loops unrolling.

unrolling by processing two channels at once, which might be either
good or bad for performance (if the registers pressure is increased

We recommend that a comprehensive volume control UI should allow
