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.

8fc9dca8cb Make serial optional to find USB devices 
If no serial is provided, then list all available USB devices (which can
be open and having a serial).

1c17f57c10 Find a list of devices instead of a single one 
Several devices may match the requested serial, but above all, this
paves the way to list all devices (when no serial is provided).

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.

1ab3692f3d Add util function to read USB descriptor string 
Use it from accept_device() to simplify (at the cost an additional
allocation for each serial, but it is not important).

It will also be useful in other functions in further commits.

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:

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.
