The pa_resampler_get_delay() function allows to retrieve the current resampler
delay in input samples for all supported resamplers. The return value is a double
to maintain precision when using variable rate resamplers. Because in many places
the delay is needed in usec, pa_resampler_get_delay_usec() was also supplied.
The speex resampler now skips leading zero samples to provide meaningful delay values.
In the next patch, the pa_resampler_prepare() function will be used to train the
resampler after a rewind. It takes data from a history memblockq and runs it through
the resampler. The output data is discarded.
To make this logic possible, the soxr resampler had to be converted to use variable
rate. The fixed rate version has a variable delay, therefore the logic above could
not be applied. Additionally, with fixed rate, the delay is larger than 150ms in
some situations, while with variable rate the delay is fixed and comparable to the
other resamplers.

A new memblockq is added to the sink input code to keep some history of the
input data. The queue is kept in sync with the render memblockq. The old input
data will be used to prepare the resampler after a rewind.
pa_resampler_request() and pa_resampler_result() have been changed to round
as good as possible to avoid loosing or duplicating samples during rewinds.

When sink is suspended for reconfiguration changing sample spec, upon resume
internal thread_info max_request and max_rewind are out of date and possibly
not aligned to frame size anymore.
Recalculate thread max_request and max_rewind before resuming sink.

When ICE I/O error occurs ICE connection is closed via IceCloseConnection.
This causes crash while releasing session manager connection later because
this ICE connection was initiated and is managed by session manager, and it will
attempt to close this ICE connection again.
Fix this by closing session manager connection instead.

Commit 7fd89e491 ("bluetooth: Try to reconnect SCO") introduces a call
to pa_msleep but failed to include the header, resulting in a:
../pulseaudio/src/modules/bluetooth/backend-native.c: In function ‘sco_acquire_cb’:
../pulseaudio/src/modules/bluetooth/backend-native.c:336:17: warning: implicit declaration of function ‘pa_msleep’ [-Wimplicit-function-declaration]
336 | pa_msleep(300);
| ^~~~~~~~~
(Un)fortunately this implicit declaration gets resolved at link-time,
otherwise the issue would have been caught sooner.

Just like the manpage these written out log levels should correspond to
the numerical values listed before, intead of being in the opposite
order and provoking thoughts of the relation being the wrong way around
where 0=debug and 4=error.

Requiring user to invoke send-message with correctly quoted parameters string
is not good for usability. Wrap parameters string into JSON string and try
again. If that works, log a warning use wrapped JSON string with parameters.
As an example these two commands will now invoke the same action:
pactl send-message /card/bluez_card... switch-codec '"CODECNAME"'
pactl send-message /card/bluez_card... switch-codec CODECNAME

Check whether a Bluetooth profile is supported both by the remote device
and the local host before creating a card profile for it.
This is useful when some of the media profiles have not been registered
with bluetoothd because ex., oFono is not running and the headset
backend is not available.

The remote device list of UUIDs reflects which profiles are supported by
the remote device alone. We currently rely solely on this list to decide
if a certain card profile is supported, and thus should be created and
get connected.
This used to be accurate when the Bluetooth modules were first written,
but now BlueZ is more dynamic and local profile support can be added or
removed during runtime. The adapter's list of UUIDs is an accurate
representation of the profiles supported by the local host at a certain
moment.
This commit combines the list of UUIDs supported by remote device and
the list of UUIDs supported by the local host to determined whether a
Bluetooth profile is actually supported or not, and whether it should be
expected to get connected during device connection.

When the SCO connection is in use, if you disconnect first and then connect,
the SCO connection will occasionally fail, and the Bluetooth error code is 42
(0x2A in hexadecimal). This is usually because an error occurred when the SCO
connection was initiated, we need to try to reconnect to optimize the handling
of this problem. The log returned by the kernel is as follows:
Bluetooth: sco_connect_cfm: hcon 0000000003328902 bdaddr 40:ef:4c:0c:11:f0 status 42
Bluetooth: sco_sock_connect status is -38
