EAGAIN was only handled on receive_frame.

In practice, it should not be necessary, since one packet always
contains one frame. But just in case.

0541f1bff2 Hide the window immediately on close
The screen may not be destroyed immediately on close to avoid undefined
behavior, because it may still receive events from the decoder.

0272e6dc77 Assert screen closed on destroy
The destruction order is important, but tricky, because the screen is

being closed.

fe8de893ca Privatize recorder threading
The fact that the recorder uses a separate thread is an internal detail,
so the functions _start(), _stop() and _join() should not be exposed.

Instead, start the thread on _open() and _stop()+_join() on close().

2ddf760c09 Make video_buffer more generic
The video buffer took ownership of the producer frame (so that it could
swap frames quickly).

In order to support multiple sinks plugged to the decoder, the decoded
frame must not be consumed by the display video buffer.

Therefore, move the producer and consumer frames out of the video
buffer, and use FFmpeg AVFrame refcounting to share ownership while
avoiding copies.

55806e7d31 Remove option --render-expired-frames
This flag forced the decoder to wait for the previous frame to be
consumed by the display.

It was initially implemented as a compilation flag for testing, not
intended to be exposed at runtime. But to remove ifdefs and to allow
users to test this flag easily, it had finally been exposed by commit
ebccb9f6cc.

In practice, it turned out to be useless: it had no practical impact,
and it did not solve or mitigate any performance issues causing frame
skipping.

But that added some complexity to the codebase: it required an
additional condition variable, and made video buffer calls possibly
blocking, which in turn required code to interrupt it on exit.

To prepare support for multiple sinks plugged to the decoder (display
and v4l2 for example), the blocking call used for pacing the decoder
output becomes unacceptable, so just remove this useless "feature".

d0739911a3 Forward DOWN and UP separately for right-click
The shortcut "back on screen on" is a bit special: the control is
requested by the client, but the actual event injection (POWER or BACK)
is determined on the device.

To properly inject DOWN and UP events for BACK, transmit the action as
a control parameter.

If the screen is off:
 - on DOWN, inject POWER (DOWN and UP) (wake up the device immediately)
 - on UP, do nothing
If the screen is on:
 - on DOWN, inject BACK DOWN
 - on UP, inject BACK UP

A corner case is when the screen turns off between the DOWN and UP
event. In that case, a BACK UP event will be injected, so it's harmless.

As a consequence of this change, the BACK button is now handled by
Android on mouse released. This is consistent with the keyboard shortcut
(Mod+b) behavior.

cb9c42bdcb Use a callback to notify frame skip
A skipped frame is detected when the producer offers a frame while the
current pending frame has not been consumed.

However, the producer (in practice the decoder) is not interested in the
fact that a frame has been skipped, only the consumer (the renderer) is.

Therefore, notify frame skip via a consumer callback. This allows to
manage the skipped and rendered frames count at the same place, and
remove fps_counter from decoder.

c0c4ba7009 Add intermediate frame in video buffer
There were only two frames simultaneously:
 - one used by the decoder;
 - one used by the renderer.

When the decoder finished decoding a frame, it swapped it with the
rendering frame.

Adding a third frame provides several benefits:
 - the decoder do not have to wait for the renderer to release the
   mutex;
 - it simplifies the video_buffer API;
 - it makes the rendering frame valid until the next call to
   video_buffer_take_rendering_frame(), which will be useful for
   swscaling on window resize.

The size, point and position structs were defined in common.h. Move them
to coords.h so that common.h could be used for generic code to be
included in all source files.

037be4af21 Fix compat missing include
The header libavformat/version.h was included, but not
libavcodec/version.h.

As a consequence, the LIBAVCODEC_VERSION_INT definition depended on the
caller includes.

d580ee30f1 Separate process wait and close
On Linux, waitpid() both waits for the process to terminate and reaps it
(closes its handle). On Windows, these actions are separated into
WaitForSingleObject() and CloseHandle().

Expose these actions separately, so that it is possible to send a signal
to a process while waiting for its termination without race condition.

This allows to wait for server termination normally, but kill the
process without race condition if it is not terminated after some delay.
