b8d7f36ba3 Fix SC_EXIT_CODE_NONE value
The exit code on windows is stored in a DWORD, an unsigned long:
<https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-dtyp/262627d8-3418-4627-9218-4ffe110850b2>

Use the max value of this type for SC_EXIT_CODE_NONE.

91418c79ab Add OTG mode
Add an option --otg to run scrcpy with only physical keyboard and mouse
simulation (HID over AOA), without mirroring and without requiring adb.

To avoid adding complexity into the scrcpy initialization and screen
implementation, OTG mode is implemented totally separately, with a
separate window.

1a03206e36 Detect USB device disconnection
The device disconnection is detected when the video socket closes.

In order to introduce an OTG mode (HID events) without mirroring (and
without server), we must be able to detect USB device disconnection.

This feature will only be used in OTG mode.

37987b822e Make acksync optional for AOA initialization
Acksync is used to delay HID events until some request (in practice,
device clipboard synchronization) is acknowledged by the device.

This mechanism will not be necessary for OTG mode.

0ee9e2ff51 Expose function to find a USB device
The device was automatically found by sc_usb_connect(). Instead, expose
a function to find a device from a serial, and let the caller connect to
the device found (if any).

This will allow to list all devices first, then select one device to
connect to.

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:

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.
