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.

fb9f9848bd Use a callback to notify a new frame
Make the decoder independant of the SDL even mechanism, by making the
consumer register a callback on the video_buffer.

c50b958ee4 Initialize screen before starting the stream
As soon as the stream is started, the video buffer could notify a new
frame available.

In order to pass this event to the screen without race condition, the
screen must be initialized before the screen is started.

441d3fb119 Make video buffer more generic
Video buffer is a tool between a frame producer and a frame consumer.

For now, it is used between a decoder and a renderer, but in the future
another instance might be used to swscale decoded frames.

cb197ee3a2 Move fps counter out of video buffer
In order to make video buffer more generic, move out its specific
responsibility to count the fps between the decoder and the renderer.

b16b65a715 Simplify default values
It makes sense to extract default values for bitrate and port range
(which are arbitrary and might be changed in the future).

However, the default values for "max size" and "lock video orientation"
are naturally unlimited/unlocked, and will never be changed. Extracting
these options just added complexity for no benefit, so hardcode them.

0538e9645b Improve error handling in screen initialization
After the struct screen is initialized, the window, the renderer and the
texture are necessarily valid, so there is no need to check in
screen_destroy().

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.

97b001e7c0 Fix undefined left shift
Small unsigned integers promote to signed int. As a consequence, if v is
a uint8_t, then (v << 24) yields an int, so the left shift is undefined
if the MSB is 1.

Cast to uint32_t to yield an unsigned value.

Reported by USAN (meson x -Db_sanitize=undefined):

    runtime error: left shift of 255 by 24 places cannot be represented
    in type 'int'

b8edcf52b0 Simplify process_wait()
The function process_wait() returned a bool (true if the process
terminated successfully) and provided the exit code via an output
parameter exit_code.

But the returned value was always equivalent to exit_code == 0, so just
return the exit code instead.

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.
