This creates a longer filter that is more complex and less sensitive to
incorrect delay reporting from the hardware. There is also a
delay-agnostic mode that can eventually be enabled if required.
In some very quick testing, not enabling this seems to provide better
results during double-talk.

Previously a missing key would cause this kind of log output:
D: [pulseaudio] module-device-manager.c: Database contains invalid data for key: sink:auto_null (probably pre-v1.0 data)
D: [pulseaudio] module-device-manager.c: Attempting to load legacy (pre-v1.0) data for key: sink:auto_null
D: [pulseaudio] module-device-manager.c: Size does not match.
D: [pulseaudio] module-device-manager.c: Unable to load legacy (pre-v1.0) data for key: sink:auto_null. Ignoring.
That is now replaced with
D: [pulseaudio] module-device-manager.c: Database contains no data for key: sink:auto_null
If 'pa_modargs_new' returns a NULL, we need to be careful to not call
'pa_modargs_free' in the failure path since it requires that we pass it
a non-null argument. Also updates 'module-bluetooth-policy.c:pa__init'
to follow the standard "goto fail" pattern used everywhere else.

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.

This isn't a great fix, but we need ALSA API to do this right. In the
mean time, USB devices work fine with timer-based scheduling, so there's
no reason to force a large minimum latency by disabling tsched on them.
This forces the canceller engine to be invoked even if playback is not
currently active. We need to do this for cases where the engine provides
additional processing that is independent of playback, such as noise
suppression and AGC.

This allows a configuration scheme where after loading configuration
from "somefile", the parser loads configuration from files in
directory "somefile.d". This feature needs to be enabled on a per-file
basis, though, and this patch doesn't yet enable the feature for any
files.
When synthesized alsa path is freed there is an assert from NULL
proplist. Create empty proplist for the path to fix.

From the NetBSD manual:
The first argument of these functions is of type int, but only a very
restricted subset of values are actually valid. The argument must either
be the value of the macro EOF (which has a negative value), or must be a
non-negative value within the range representable as unsigned char.
Passing invalid values leads to undefined behavior.

pa_module_unload() takes two pointers: pa_module and pa_core.
The pa_core pointer is also available via the pa_module object,
so the pa_core argument is redundant

It doesn't work currently (fails and falls back to PCM), due to channel
count mismatch between the sink sample spec and the sample spec required
by IEC61937.
To be reverted when someone implements changing channel count without
switching profiles. This would also be required for HBR passthrough over
HDMI.

If we always write entries of the latest version, we can simplify
code a little by only handling old versions in the "entry_read"
function and assume we have the latest version everywhere else.

This makes the routing slightly more aggressive:
* It will try to route to another profile, if such a profile
is preferred by the port.
* It will allow changing profiles on transitions both to
PA_AVAILABLE_YES and PA_AVAILABLE_NO
To accommodate there is also some refactoring.

In case input or output names are filled in, we can use this to
get a better match in the profile_good_for_input/output functions
instead of guessing based on number of sources and channels.

Adding AGC broke this test, so we hard-disable the volume code in test
mode. This is probably okay for now, since at least with analog AGC, the
source volume changes and the data we get is going to be with AGC
applied, but digital gain won't be encapsulated here.
Long term, we might need to figure out how to deal with this properly.
We encountered an alsa plugin a while ago (not sure if the source
can be shared) which had mixer controls, but no descriptors to
poll for changes.
Quit early to avoid latter assertion failures.

In rtp.c:
if (sscanf(t+9, "%i %64c", &_payload, c) == 2)
the string c seems to be non-null terminated. It is later used as
following:
c[strcspn(c, "\n")] = 0;
The same piece of code is responsible for the inability of pulseaudio
on OpenWRT to handle RTP stream at the rate 48000 from another
machine:
[pulseaudio] sdp.c: Failed to parse SDP data: missing data.
It turns out that uClibc does not agree with glibc about "%64c", see

We currently only support one and two channels for volumes, and
bail out otherwise. This makes Xonar users unhappy because they
have a volume with eight channels, and bailing out means they
don't have a path/port at all.
This way they will at least have a port, which will in turn make
the gnome/unity UI behave better.

In case the same jack causes one port to become available and another
one unavailable, the available should be reported first.
This is to avoid unnecessary changes: e g, consider a 'Headphone Jack'
making 'Headphone' available and 'Speaker' unavailable. In case the
unavailable change triggers first, and there is also a currently available
third port (e g 'Digital out'), the routing system might choose to route
to this port because neither of the 'Speaker' and 'Headphone' ports are
available.

Originally pointed out by Georg Chini.
Calculating buffer = buffer + (send_counter - recv_counter)
in one branch and buffer = 2 * buffer - (recv_counter - send_counter)
looks very obviously wrong. In other words, before the patch, the
contribution from the previous lines was double-counted.
