server_stop().

This allows to interrupt any blocking accept() with correct
synchronization without additional complexity.

0426708544 Run the server from a dedicated thread
Define server callbacks, start the server asynchronously and listen to
connection events to initialize scrcpy properly.

It will help to simplify the server code, and allows to run the UI event
loop while the server is connecting. In particular, this will allow to
receive SIGINT/Ctrl+C events during connection to interrupt immediately.

5b9c88693e Wait using a condition variable in server
Currently, server_stop() is called from the same thread as
server_connect_to(), so interruption may never happen.

This is a step to prepare executing the server from a dedicated thread.

ac23bec144 Expose socket interruption
On Linux, socket functions are unblocked by shutdown(), but on Windows
they are unblocked by closesocket().

Expose net_interrupt() and net_close() to abstract these differences:
 - net_interrupt() calls shutdown() on Linux and closesocket() on
   Windows (if not already called);
 - net_close() calls close() on Linux and closesocket() on Windows (if
   not already called).

This simplifies the server code, and prevents a data race on close
(reported by TSAN) on Linux (but does not fix it on Windows):

e4163321f0 Delay HID events on Ctrl+v
When Ctrl+v is pressed, a control is sent to the device to set the
device clipboard before injecting Ctrl+v.

With the InputManager method, it is guaranteed that the device
synchronization is executed before handling Ctrl+v, since the commands
are executed on the device in sequence.

However, HID are injected from the computer, so there is no such
guarantee. As a consequence, on Android, Ctrl+v triggers a paste with
the old clipboard content.

To workaround the issue, wait a bit (2 milliseconds) from the AOA
thread before injecting the event, to leave enough time for the
clipboard to be set before injecting Ctrl+v.

207082977a Add support for USB HID keyboard over AOAv2
This provides a better input experience, by simulating a physical
keyboard. It converts SDL keyboard events to proper HID events, and send
them over AOAv2.

This is a rewriting and bugfix of the origin code from @amosbird:
<https://github.com/Genymobile/scrcpy/issues/279#issuecomment-453819354>

The feature is enabled the command line option -K or --hid-keyboard,
and is only available on Linux, over USB.

79278961b9 Implement buffering
To minimize latency (at the cost of jitter), scrcpy always displays a
frame as soon as it available, without waiting.

However, when recording (--record), it still writes the captured
timestamps to the output file, so that the recorded file can be played
correctly without jitter.

Some real-time use cases might benefit from adding a small latency to
compensate for jitter too. For example, few tens of seconds of latency
for live-streaming are not important, but jitter is noticeable.

Therefore, implement a buffering mechanism (disabled by default) to add
a configurable latency delay.

408a301201 Notify new frames via callbacks
Currently, a frame is available to the consumer as soon as it is pushed
by the producer (which can detect if the previous frame is skipped).

Notify the new frames (and frame skipped) via callbacks instead.

This paves the way to add (optional) buffering, which will introduce a
delay between the time when the frame is produced and the time it is
available to be consumed.

5caeab5f6d Fix v4l2 data race
The v4l2_sink implementation directly read the internal video_buffer
field "pending_frame_consumed", which is protected by the internal
video_buffer mutex. But this mutex was not locked, so reads were racy.

Lock using the v4l2_sink mutex in addition, and use a separate field to
avoid depending on the video_buffer internal data.

7dca5078e7 Initialize controller even if there is no display
The options --no-display and --no-control are independent.

The controller was not initialized when no display was requested,
because it was assumed that no control could occur without display. But
that's not true (anymore): for example, it is possible to pass
--turn-screen-off.
