pa_source_state_t can have value PA_SOURCE_INVALID_STATE, not
PA_SINK_INVALID_STATE. It happens to be the same here, but it can break
sometimes.
Issue detected by PVS Studio.
The file descriptors are read from the iochannel just like the creds are.
So instead of passing just creds (and creds_valid), we now pass the
entire pa_ancil struct.

Make the PulseAudio tunnel behave the same way as a client
when it comes to figuring out how to connect to the current
PulseAudio daemon. This can be useful if you start a second
PulseAudio instance for e.g. network access.
u->sink->state is not yet updated, so the state must be read from
u->sink->thread_info.state. This makes pausing and resuming of the
smoother happen at the right time.
Thanks to Pierre Ossman for the patch.
This patch removes all occurrences of double and triple
newlines.
Command used for this:
find . -type d \( -name ffmpeg \) -prune -o \
-regex '\(.*\.[hc]\|.*\.cc\)' \
-a -not -name 'adrian-aec.*' -a -not \
-name reserve.c -a -not -name 'rtkit.*' \
-exec sed -i -e '/^$/{N;s/^\n$//}' {} \;
Two passes were needed to remove triple newlines.
The excluded files are mirrored files from external sources.
This patch replaces every occurrence of ')\n{' with ') {'.

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.

module-tunnel doesn't care about the proplist contents, so
pa_tagstruct_get_proplist() is only used for removing the
data from the tagstruct buffer. In that case it's more
convenient to just pass NULL as the proplist argument.
The tunnel source has been broken since protocol v22 (PA 1.0),
and connecting fails with a protocol error. Fix.

The commit 7ebc5033 resulted in segfaults, because format->plist was not allocated.
The solution is not to allocate pa_format_info on the stack, but to properly use pa_format_info_new().
Also a typo regarding pa_tagstruct_putu8 is corrected.
Some sink flags are really just a product of what callbacks
are set on the device. We still enforce a degree of sanity
that the flags match the callbacks set, but we also set the
flags automatically in our callback setter functions to
help ensure that a) people use them and b) flags & callbacks
are kept in sync.
This is not currently useful but future commits will make further
changes concerning automatic setting of flags and event delivery
that makes this structure necessary.
This updates the tunnel module for protocol version >= 19.
module-tunnel-sink does not proxy server-side passthrough support (yet).
This would require a few more changes, namely keeping track of what
formats are available and if any other sink inputs are connected on the
server-side.

tunnel: Fix tunnel streams with recent servers
Prompted by bug #750. Thanks to Emil Renner Berthing for the original
patch.
- We now implement a logic where the sink maintains two distinct
volumes: the 'reference' volume which is shown to the users, and the
'real' volume, which is configured to the hardware. The latter is
configured to the max of all streams. Volume changes on sinks are
propagated back to the streams proportional to the reference volume
change. Volume changes on sink inputs are forwarded to the sink by
'pushing' the volume if necessary.
This renames the old 'virtual_volume' to 'real_volume'. The
'reference_volume' is now the one exposed to users.
By this logic the sink volume visible to the user, will always be the
"upper" boundary for everything that is played. Saved/restored stream
volumes are measured relative to this boundary, the factor here is
always < 1.0.
- introduce accuracy for sink volumes, similar to the accuracy we
already have for source volumes.
- other cleanups.
Move the mainloop to monotonic based time events.
Introduces 4 helper functions:
pa_{context,core}_rttime_{new,restart}(), that fill correctly a
timeval with the rtclock flag set if the mainloop supports it.
Both mainloop-test and mainloop-test-glib works with rt and timeval
based time events. PulseAudio and clients should be fully functional.
This patch has received several iterations, and this one as been
largely untested.

Completely rework mixer logic. This now allows controlling a full set of
elements from a single sink's volume slider/mute button.
This also introduces sink and source "ports" that can be used to choose
different input or output ports with the UI. (i.e. "mic"/"line-in" or
"speaker"/"headphones".
The mixer paths and device maps are now configered in external
configuration files and can be tweaked as necessary.
The primary reason for this change is to allow time graphs that do not
go through the origin and hence smoothing starting from the origin is
not desired. This change will allow passing time data into the smoother
while paused and then abruptly use that data without smoothing using the
'quick fixup' flag when resuming.
Primary use case is allowing recording time graphs where the data
recorded originates from a time before the stream was created. The
resulting graft will be shifted and should not be smoothened to go
through the origin.
