When running meson test without a preceding ninja build, we end up with
missing libraries. This somehow happened to work until recently but now
it triggers an issue with libspa-dbus.so not being available during the
valgrind test run, causing a test case to fail.
Add a method to enable/disable the denormals flush-to-zero and
denormals-as-zero CPU options.
Add a config option to make it possible to disable this again.
Fixes high CPU usage when dealing with denormals, which can happen
in many DSP functions.

Some devices (Bose Mini Soundlink II, Air 1 Plus, ...) don't enable
AVRCP volume control, or fail to enable it before a hardware button is
pressed. However, these devices appear to enable it, if an AVRCP player
is present.
As a workaround, register a dummy AVRCP player for each adapter. It only
displays the current transport acquisition state as playing/stopped, but
just its presence appears to be enough to make devices behave.
Multiple AVRCP players interfere with each other, as BlueZ uses the one
registered earliest as the default player. So add also a config option
for disabling this. (It's not common to have mpris-proxy etc. running,
so defaulting to true should be OK.)

There's a report that on Intel 8086:2723 + Sony WH-1000XM4, the connect
probe shuts the device down.
So, use an invalid dst address instead, since we don't need the host to
be up.

The msbc capability connection probe seems to cause problems on Intel
Bluetooth 8087:0a2b (Intel 8265), resulting to subsequent connections
apparently ending up with wrong altsetting.
According to testing, the problem is connecting to self, so connect to
device instead.
Fixes#1671
There is a report (#1342) of a device setting multiple bits for AAC
object type in SetConfiguration, although this appears to be forbidden.
It's not completely clear if this was due to e.g. some BlueZ bug, but it
should be safe to be lax and try to guess what is wanted in such case,
instead of being strict, in case it was due to device bug.
Previously, `log-patterns.c` was included in two other source files
(`journal.c` and `logger.c`). It was also specified in the sources
list for the libspa-support library, which resulted in the unnecessary
independent compilation of the file, generating "defined but not used"
warnings.
Extract the function definitions into `log-patterns.h` and
use that in `journal.c` and `logger.c`, and remove the inclusion
of `log-patterns.c` from both.
Don't use the previously skipped sample to calculate the remaining
amount of samples or else we remove one sample too much in some cases
and cause distortion, mostly when downsampling.
Fixes#1646
Intel 8087:0029 at Firmware revision 0.0 build 191 week 21 2021 on
kernel 5.13.19 produces CVSD data stream that consists of 96-byte data
packets interleaved with 96-byte zero packets.
This seems to not occur on other adapters, which usually produce only
48-byte data packets.
Don't do a blocking probe of native backend presence, because it may
trigger DBus activation for Bluez. If the DBus activation fails, it
ends up blocking until timeout.
ofono/hsphfpd usually don't have DBus activation configured, so they
fail instantly (which is why this problem was not encountered, even
though they do blocking calls on startup in previous pipewire versions
too).
Instead, select the backend once we have Bluez objects listed.
HAVE_DATA|NEED_DATA signals that the graph can continue processing.
OK means that the node will continue asynchronously later. This
is needed to make the dummy driver work as a follower.
BlueZ 6 is planning to make most of libbluetooth private. In
particular, the direct hci access is planned to be removed. This is
currently used for determining adapter msbc support.
Instead of using libbluetooth API, try to determine msbc support by
a connect() attempt, which the kernel should reject when not supported.
The requests_ vector contains the requests created for a camera on start()
but the vector elements are not removed on camera stop(). This leads to a
segfault, when these requests that are no longer valid are queued again.
Also move the streamName_ map clear to LibCamera::stop() where it should
be, since its elements are added in the LibCamera::start() function.
