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.

Without -avoid-version, libtool creates a libwebrtc-util.so.0 and
libwebrtc-util.so.0.0.0 which are not cleaned up by make uninstall,
which in turn causes make distcheck to fail.

This moves out the webrtc bits into a small helper library to shield the
rest of module-echo-cancel from being linked with a C++ linker. This is
required because automake will _always_ link module-echo-cancel in C++
mode if any of its deps (even conditional ones) are in C++.

Many desktops have headphone on the front and line outs on the back.
Sometimes this means that the headphone is labelled "Front Headphone Jack",
but the volume controls are only "Headphone Playback Volume", i e,
without the "Front" prefix.

Some devices have inverted right channel, so when you add left and right,
the result is silence, or very faint sound. In recent kernels (3.5,
perhaps also 3.4) these are starting to be marked with a special
"Inverted Internal Mic" capture switch.
While we might want to add some reverse summing mechanism in the
future, for now, we just turn the thing off to avoid the problem of
recording silence.

Several laptops have speaker ports, and/or internal mic ports, but we have
no way of detecting that. So we make the port(s) always show up for these
devices.

When a Bluetooth headset is connected only to HFP profile (not connected
to A2DP) and host streams to it, a crash occurs if host disconnects.
When HFP disconnects, audio thread will fail on POLLHUP then generate
a message to set PA profile to Off before ending.
If this message is managed before PA unload bluetooth device module,
all works fine.
But, if this message is managed during module unload, this finish by
re-entrance in release code (stop_thread) and a crash.
This fix prevents to process profile change when module is unloading.
pa_bool_t and dbus_bool_t cannot be used interchangably since their size
might (and do) vary. This caused a crash on some systems which was
reported and root caused by: Aidan Thornton <makosoft@googlemail.com>.

Changes in v2:
- Call the mapping a generic 4-channel input mapping
instead of a 4-channel mic array mapping. The mapping
will be used also by sound cards that have two stereo
input jacks, so in those cases talking about mic arrays
is wrong.
- Added a comment about using the "hw" device name.

libsamplerate_resample() assumed that src_process() would
always consume the whole input buffer. That was an invalid
assumption leading to crashes.
This patch adds a leftover memchunk for storing any
non-consumed input. When pa_resampler_run() is called next
time, the leftover is prepended to the new input.
Changes in v3:
- Make the calculations in pa_resampler_result() and
pa_resampler_max_block_size() more readable and more
correct.
- Rework the leftover storing: instead of using a dedicated
buffer for it, store it in the beginning of remap_buf.
This can avoid some memory copying. (The idea was
suggested by Wang Xingchao.)
- Use a generic save_leftover() function instead of doing
the leftover copying in the resampler implementation.
- Use the leftover logic also with the speex and ffmpeg
resamplers.
[ed: dropped the speex bit since the API guarantees that
it will consume everything -- Arun]
Changes in v2:
- If add_leftover() is called with zero-length input while
the leftover length is non-zero, we don't try to acquire
the input memblock.
- Instead of taking a reference to the original input in
libsamplerate_resample(), we copy the leftover data to a
new memblock. This is done, because otherwise, if the
input is one of the internal buffers, the data can get
overwritten before reading it in add_leftover().
- Store add_leftover_buf size in bytes instead of samples
(more convenient, but less consistent with other code).

All utilities should have the --help and --version command line options.
These two were added to pacmd, also the goto label was changed from fail
to quit like in the other utilities.

Due to the formatting of `README` the only occurence of PulseAudio in a
text is capitalized. People reading `README` should at least see the
correct spelling once.
In contrast to reformat just add a spelling section as an easy solution.
Since it is not that important the last place in the ordering might
suffice.
State which thread calls set_port in which scenario.

Log in as user A, fast user switch to user B, let user B change
port, volume or mute status, then switch back to user A.
At this point we must make sure that the ALSA and PA volumes are
synchronised by writing to the ALSA mixer when the ALSA device
becomes available.

If deferred volumes were activated, set_volume does not really set
the volume, and is probably only meant to be called from the main
thread.
As we're currently really setting the port and the mute here (i e
modifying ALSA), we should really modify the volume as well.

Make sure we can't be called into by remaining references to
sink-inputs and source-outputs after we have unloaded, as
that will likely lead to segfaults.
