The Bluetooth Low Energy MIDI code added a few legacy function declarations
that fail when building with -Werror=strict-prototypes. The fix is same as
before: add a void to the empty function argument list.

FFmpeg integration in pw-cat does not strictly require Compress-Offload;
for example, there could be other nodes in the graph that can handle
compressed audio.

* Decouple FFmpeg integration in pw-cat from the ffmpeg option; if
one wants to use Compress-Offload but not the ffmpeg SPA plugin,
it is then possible to just pass -Dpw-cat-ffmpeg=enabled to meson.
Likewise, this also makes it possible to build the ffmpeg plugin
without extending pw-cat.
* tinycompress does not need to be detected in the root meson.build,
since it is only needed by the alsa plugin.
WirePlumber checks for the ENCODED audio format to determine if the
format is compressed/encoded. Without this info, it is not able
to automatically link compressed audio nodes.
Use stdalign.h instead of union.
Fix some refcounting and return values.
Fail early in add_filters.
Minor style cleanups.
Less magical spa_dbus_async_call.
As server, put node nick in GATT Characteristic User Description, so
that clients have some information which endpoint is which in case we
have multiple. This is not in BLE MIDI standard, but cannot hurt.
As client, make use of that information, if present.
Implement BLE MIDI node, providing an input and output port. MIDI data
received is normalized and produced on output port. Data from input
port is converted to BLE MIDI and sent to the device.
Event timestamps come from device clock, whose offset to wall clock we
determine by correlating packet reception times with their timestamps.
The jitter in packet reception is likely much larger than device clock
error, so we average over that.
The module can:
- Make a sink that sends all or some channels to other sinks.
- Make a source that combines multiple sources into one.
The selection of what streams to combine is implemented with rules so
that the selection is very configurable. By default all Audio/Sink or
Audio/Source nodes are selected.
