0ae10f2b39 Improve slope estimation on start
The first frames are typically received and decoded with more delay than
the others, causing a wrong slope estimation on start.

To compensate, assume an initial slope of 1, then progressively use the
estimated slope.

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.

4d8bcfc68a Extract current video_buffer to frame_buffer
The current video buffer only stores one pending frame.

In order to add a new buffering feature, move this part to a separate
"frame buffer". Keep the video_buffer, which currently delegates all its
calls to the frame_buffer.

28bce48d47 Relax v4l2_sink lock constraints
To fix a data race, commit 5caeab5f6d
called video_buffer_push() and video_buffer_consume() under the
v4l2_sink lock.

Instead, use the previous_skipped indication (initialized with video
buffer locked) to lock only for protecting the has_frame flag.

This enables the possibility for the video_buffer to notify new frames
via callbacks without lock inversion issues.

32e692d5d2 Replace delay by deadline in timedwait()
The function sc_cond_timedwait() accepted a parameter representing the
max duration to wait, because it internally uses SDL_CondWaitTimeout().

Instead, accept a deadline, to be consistent with
pthread_cond_timedwait().

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.

9b89b7ab72 Center the window on resize-to-fit
When removing the black borders (by double-clicking on them, or by
pressing MOD+w), the window is resized to fit the device screen, but its
top-left position was left unchanged.

Instead, move the window so that the new window area is at the center of
the old window area.

7343b233e4 Render screen on window restored
It should not be necessary, since screen_render() is called just after
on SDL_WINDOWEVENT_EXPOSED, but in practice the window content might not
be correctly displayed on restored if a rotation occurred while
minimized.

Note that calling screen_render() twice in a row on
SDL_WINDOWEVENT_EXPOSED also "fixes" the issue.
