If a stream is started corked and remains corked, the sink/source
remained idle without being properly suspended. This patch fixes
that issue.

Steps to reproduce:
1) Leave LFE remixing disabled (the default)
2) Start playback of stereo material on e g 5.1 surround, notice nothing in LFE
3) Now change profile to e g 4.0 surround and then back to 5.1 surround
4) Notice that LFE channel is now remixed

This makes sure that there is no window between pa_sink/source_new()
and _put() where enumerating sinks/sources causes an assert (several
calls in sink/source_get_info need a linked sink or source).
A segfault was reported on this line:
pa_return_val_if_fail(PA_SINK_IS_LINKED(pa_sink_get_state(data->sink)), -PA_ERR_BADSTATE);
After expanding the pa_sink_get_state() macro, the line looks like
this:
pa_return_val_if_fail(PA_SINK_IS_LINKED(data->sink->state), -PA_ERR_BADSTATE);
So data->sink was apparently NULL. That could happen if we try to fall
back to the default sink, but format negotiation fails.
This bug was introduced in commit
71816ecb7f.

This fixes a build error with mingw32:
pulsecore/.libs/libpulsecommon_4.99_la-lock-autospawn.o: In function `unref':
/home/abuild/rpmbuild/BUILD/pulseaudio-4.99.2/src/pulsecore/lock-autospawn.c:123: undefined reference to `pa_thread_free_nojoin'
collect2: error: ld returned 1 exit status
pa_thread_free_nojoin() was initially only implemented for the pthread
based pa_thread backend, because it was incorrectly assumed that
autospawning (the only user of pa_thread_free_nojoin()) is not used on
Windows.

Reintroduces a cleaned-up version of commit 30ce3a14e5 which
was reverted by 1ce71cbd82; for more information see

The patch intends to reduce computational load when resampling AND remapping. The PA
resampler performs the following steps:
sample format conversion -> remapping -> resampling -> sample format conversion
In case the number of output channels is higher than the number of input channels, the
resampler has to be run more often than necessary. E.g. in case of mono to 4-channel remapping,
the resampler runs on 4 channels separately.
To ímprove this, the PA resampler pipeline is made adaptive:
if out-channels <= in-channels:
sample format conversion -> remapping -> resampling -> sample format conversion
if out-channels > in-channels:
sample format conversion -> resampling -> remapping -> sample format conversion

the patch changes the interface of the (internal) fit_buf() function:
fit_buf() manages the memblock of the buf chunk, it reallocates the memblock
if the requested number of bytes ('len') if larger than the memblock's size ('size')
and optionally preserves 'copy' bytes
the code should be in line with the comment now

rindex() appears to be "non-standard" to an extent, and it caused a
build failure on mingw32.
From the man page of rindex(): "POSIX.1-2008 removes the
specifications of index() and rindex(), recommending strchr(3) and
strrchr(3) instead."
This fixes an assertion crash:
[pulseaudio] source.c: Assertion 'PA_SOURCE_IS_LINKED(s->state)' failed at pulsecore/source.c:734, function pa_source_update_status(). Aborting.
The crash happened when a Bluetooth headset profile was changed from
a2dp to hsp. During the profile change three devices are created:
a sink, a monitor source for the sink, and a regular source. First
pa_sink/source_new() are called for each device, and that puts the
devices to u->core->sinks/sources. Then, pa_sink_put() is called for
the sink, and that in turn calls pa_source_put() for the source. At
that point module-device-manager decides to reroute all source
outputs. The non-monitor source that the Bluetooth card created hasn't
been linked yet at this stage, because it will only be linked after
the sink and the monitor source have been linked. So,
module-device-manager should take into account during the rerouting
that not all sinks and sources are necessarily linked. This patch does
that.

Not having ORC_SOURCE defined results in different tarballs depending on
whether the dev issuing 'make dist' has orc support enabled or disabled.
Specifying ORC_SOURCE unconditionally addresses that, without causing
negative effects on users not having orc in the end.
The bigger than usual bump in libpulse-simple was warranted by the
change in pa_simple_flush() that allows also record streams to be
flushed. There are no changes to the function signature, but it's in
practice a change in the ABI anyway, because new clients using the new
possibility won't work with older versions of the library.
libpulse-mainloop-glib got a bug fix in commit
68156d3f79.
A crash was observed that was caused by pa_memblockq_peek() returning
a NULL memblock in sink_input_pop_cb(). The scenario where this was
happening was
1. Delete 2 rtp-recv's connected to a ladspa-sink
2. Delete ladspa-sink
3. Delete alsa-sink
4. Create alsa-sink
5. Create ladspa-sink
6. Create 2 rtp-recv's connected to the ladspa-sink
The crash was probably caused by a rewind that made the read index go
negative while the write index was at least zero, causing there to be
a gap in the memblockq. The problematic rewind might have been caused
by adding the rtp-recv stream to the ladspa-sink. That has not been
proven, but this looks very similar to the bug that was fixed in
module-virtual-sink in commit 6bd34156b1.
pulsecore/core-format.c was recently added to libpulsecommon, and
core-format.c depends on functions in libpulse, which libpulsecommon
doesn't link to. That broke building with --as-needed. This patch adds
pulse/format.c to libpulsecommon, so that core-format.c doesn't need
to depend on libpulse any more. format.c pulls in also the dependency
to json-c.

The modargs are in both cases (a succesfull as well as a failed module
initialization) freed already in pa__done().
To avoid leaking modargs memory before they are assigned to u->modargs, the
code is reorganized to first allocate userdata, and then allocate the modargs.
Local variable ma is not needed anymore.

The "fix flags" (PA_SINK_INPUT_FIX_FORMAT etc.) don't work properly
with the pa_stream_new_extended() interface. This patch fixes it so
that the same effect can be achieved by leaving some of the PCM
parameters unspecified in format info objects. Also, when converting
a sample spec to a format info when using the old pa_stream_new()
interface, the "fix flags" are taken into account in that conversion.
BugLink: https://bugs.freedesktop.org/show_bug.cgi?id=68952
The check is done for clients that use pa_stream_new() but not for
clients that use pa_stream_new_extended(). This is inconsistent. We
could check that the volume channels match the channels set in the
format info struct that is passed to pa_stream_new_extended(), but
that doesn't work if the format info doesn't contain the channel
information (that can happen if the client wants the server to choose
the channel count for the stream). And it should also be possible to
pass a mono volume for a multi-channel stream. The check could be
extended to handle all these cases, but I don't see much point in
wasting time on that. The server will anyway validate the stream
parameters, it's not particularly important to fail already when the
stream is being created at the client side.
