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.

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.

1c82c3923d Compute relative PTS on the client-side
The PTS received from MediaCodec are expressed relative to an arbitrary
clock origin. We consider the PTS of the first frame to be 0, and the
PTS of every other frame is relative to this first PTS (note that the
PTS is only used for recording, it is ignored for mirroring).

For simplicity, this relative PTS was computed on the server-side.

To prepare support for multiple stream (video and audio), send the
packet with its original PTS, and handle the PTS offset on the
client-side (by the recorder).

Since we can't know in advance which stream will produce the first
packet with the lowest PTS (a packet received later on one stream may
have a PTS lower than a packet received earlier on another stream),
computing the PTS on the server-side would require unnecessary waiting.

4af317d40d Allocate AVPacket for recorder
From FFmpeg/doc/APIchanges:

    2021-03-17 - f7db77bd87 - lavc 58.133.100 - codec.h
      Deprecated av_init_packet(). Once removed, sizeof(AVPacket) will
      no longer be a part of the public ABI.

f7a1b67d66 Make stream push packets to sinks
Now that decoder and recorder implement the packet sink trait, make

fe8de893ca Privatize recorder threading
The fact that the recorder uses a separate thread is an internal detail,
so the functions _start(), _stop() and _join() should not be exposed.

Instead, start the thread on _open() and _stop()+_join() on close().

This paves the way to expose the recorder as a packet sink trait.

0ba74fbd9a Make scrcpy.h independant of other headers
The header scrcpy.h is intended to be the "public" API. It should not
depend on other internal headers.

Therefore, declare all required structs in this header and adapt
internal code.

35d9185f6c Record asynchronously
The record file was written from the stream thread. As a consequence,
any blocking I/O to write the file delayed the decoder.

For maximum performance even when recording is enabled, send
(refcounted) packets to a separate recording thread.

    UintXX   -> uintXX_t

aeda583a2c Update code style
Limit source code to 80 chars, and declare functions return type and
modifiers on a separate line.

This allows to avoid very long lines, and all function names are
aligned.

(We do this on VLC, and I like it.)
