This is an OpenPGP/MIME signed message (RFC 4880 and 3156)
The old code fetched the channel name via AudioObjectGetPropertyData()
and accessed the "returned" data as a plain char buffer.
This may or may not have worked at some point according to the Apple
CFString documentation, which warns that the actual data layout is an
implementation detail and subject to change at any time.
On recent OS X versions, this behavior led to "random data" channel
names like >H��{, H��{<.
We need to actually let AudioObjectGetPropertyData() populate a CFString
struct and convert this into a plain char buffer.
The conversion function will not free the CFString, so do that in the
caller.

CoreAudio routines that return an error status do so with the
OSStatus type, which is not a UInt32: typical OS X errors are
negative numbers.

FSF addresses used in PA sources are no longer valid and rpmlint
generates numerous warnings during packaging because of this.
This patch changes all FSF addresses to FSF web page according to
the GPL how-to: https://www.gnu.org/licenses/gpl-howto.en.html
Done automatically by sed-ing through sources.
Commit fa092af59c removed an argument to pa_rtpoll_run, but
forgot to remove that argument for all callers to pa_rtpoll_run.
This commit removes the remaining ones.

This patch replaces every occurrence of ')\n{' with ') {'.
Command used for this:
find . -type d \( -name ffmpeg \) -prune -o \
-regex '\(.*\.[hc]\|.*\.cc\)' \
-a -not -name core-util.c -a -not \
-name adrian-aec.c -a -not -name g711.c \
-exec sed -i -e '/)$/{N;s/)\n{$/) {/}' {} \;
The excluded files are mirrored files from external sources.
get_latency_us() used an uninitialized variable, and an incorrect
scope for some of the AudioObjectGetPropertyData() calls. As a result,
audio would randomly not work at all.

Since some devices can be chatty with regards to how often they return
from poll(), this adds a PA_UNLIKELY() to all the the rewind_requested
checks in our sink modules to make the general case (no rewind was
requested) the fast path.
When a rewind is requested on a sink input, the request parameters are
stored in the pa_sink_input struct. The parameters are reset during
rewind processing, and if the sink decides to ignore the rewind
request due to being suspended, stale parameters are left in
pa_sink_input. It's particularly problematic if the rewrite_bytes
parameter is left at -1, because that will prevent all future rewind
processing on that sink input. So, in order to avoid stale parameters,
every rewind request needs to be processed, even if the sink is
suspended.

Since commit 12af302a last month, cards always have at least one
profile, so there is also always an active_profile (this makes the code
more simple). However, module-coreaudio-device did not create a profile
yet, causing a crash of PulseAudio when used on OS X. This patch fixes
this crash, by adding a single "On" profile. I've also added a TODO for
adding an "Off" profile which removes all sinks and sources -- I can
work on resolving this TODO later on.
