c996a6d462 Fix socket close race condition
The server needs to interrupt the sockets on stop, but it must not close
them while other threads may attempt to read from or write to them.

In particular, the video_socket is read by the stream thread, and the
control_socket is written by the controller and read by receiver.

Therefore, close the socket only on sc_server_destroy(), which is called
after all other threads are joined.

Reported by TSAN on close:

On Windows, the file explorer does not provide any "open a terminal

Add a bat file which just runs `cmd` to easily open a terminal directly
in the scrcpy directory (so there is no need to `cd C:\path\…`).

2faf9715be Add server option raw_video_stream
For convenience, this new option forces the 3 following options:
 - send_device_meta=false
 - send_frame_meta=false
 - send_dummy_byte=false

This allows to send a raw H.264 stream on the video socket.

Concretely:

    adb push scrcpy-server /data/local/tmp/scrcpy-server.jar
    adb forward tcp:1234 localabstract:scrcpy
    adb shell CLASSPATH=/data/local/tmp/scrcpy-server.jar \
        app_process / com.genymobile.scrcpy.Server 1.21 \
        raw_video_stream=true tunnel_forward=true control=false

As soon as a client connects via TCP to localhost:1234, it will receive
the raw H.264 stream.

3ba32c2a0d Add server option send_device_meta
Similar to send_device_frame, this option allows to disable sending the
device name and size on start.

This is only useful when using the scrcpy-server alone to get a raw
H.264 stream, without using the scrcpy client.

a9429efa34 Fix downsize on error before first frame

frame, not the first packet.

In practice, the first packet is a config packet without any frame, and
MediaCodec might fail just after.

2eb6fe7d81 Downsize on error only before the first frame
The purpose of automatic downscaling on error is to make mirroring work
by just starting scrcpy without an explicit -m value, even if the
encoder could not encode at the screen definition.

It is only useful when we detect an encoding failure before the first
frame. Downsizing later could be surprising, so disable it.

75c5dc6859 Position and size the window on first frame
The optimal initial size was computed from the expected dimensions, sent
immediately by the server before encoding any video frame.

However, the actual frame size may be different, for example when the
device encoder does not support the requested size.

To always handle this case properly, position and size the window only
once the first frame size is known.
