609b098a97 Do not merge config audio packets
For video streams (at least H.264 and H.265), the config packet
containing SPS/PPS must be prepended to the next packet (the following
keyframe).

For audio streams (at least OPUS), they must not be merged.

f60b5767f4 Force --no-audio if no display and no recording
The client does not use the audio stream if there is no display and no
recording (i.e. only V4L2), so disable audio so that the device does not
attempt to capture it.

ae29e5b562 Use VideoStreamer directly from ScreenEncoder
The Callbacks interface notifies new packets. But in addition, the
screen encoder will need to write headers on start.

We could add a function onStart(), but for simplicity, just remove the
interface, which brings no value, and call the streamer directly.

a039124d5d Open recording file from the recorder thread
The recorder opened the target file from the packet sink open()
callback, called by the demuxer. Only then the recorder thread was
started.

One golden rule for the recorder is to never block the demuxer for I/O,
because it would impact mirroring. This rule is respected on recording
packets, but not for the initial recorder opening.

Therefore, start the recorder thread from sc_recorder_init(), open the
file immediately from the recorder thread, then make it wait for the
stream to start (on packet sink open()).

Now that the recorder can report errors directly (rather than making the
demuxer call fail), it is possible to report file opening error even
before the packet sink is open.

fb29135591 Initialize recorder fields from init()
The recorder has two initialization phases: one to initialize the
concrete recorder object, and one to open its packet_sink trait.

Initialize mutex and condvar as part of the object initialization.

If there were several packet_sink traits (spoiler: one for video, one
for audio), then the mutex and condvar would still be initialized only
once.

b1b33e3eaf Report recorder errors
Stop scrcpy on recorder errors.

It was previously indirectly stopped by the demuxer, which failed to
push packets to a recorder in error. Report it directly instead:
 - it avoids to wait for the next demuxer call;
 - it will allow to open the target file from a separate thread and stop
   immediately on any I/O error.

On the scrcpy-deps repo, I built FFmpeg 5.1.2 binaries for Windows with
only the features used by scrcpy.

For comparison, here are the sizes of the dll for FFmpeg 5.1.2:
 - before: 89M
 - after: 4.7M

It also allows to upgrade the old FFmpeg version (4.3.1) used for win32.
