0308ef43f2 Do not set buttons on touch events 
BUTTON_PRIMARY must not be set for touch events:

> This button constant is not set in response to simple touches with a
> finger or stylus tip. The user must actually push a button.

<https://developer.android.com/reference/android/view/MotionEvent#BUTTON_PRIMARY>

Fixes #2169 <https://github.com/Genymobile/scrcpy/issues/2169>

40febf4a91 Use device id 0 for touch/mouse events 
Virtual device is only for keyboard sources, not mouse or touchscreen
sources. Here is the value of InputDevice.getDevice(-1).toString():

    Input Device -1: Virtual
      Descriptor: ...
      Generation: 2
      Location: built-in
      Keyboard Type: alphabetic
      Has Vibrator: false
      Has mic: false
      Sources: 0x301 ( keyboard dpad )

InputDevice.getDeviceId() documentation says:

> An id of zero indicates that the event didn't come from a physical
> device and maps to the default keymap.

<https://developer.android.com/reference/android/view/InputEvent#getDeviceId()>

However, injecting events with a device id of 0 causes event.getDevice()
to be null on the client-side.

Commit 26529d377f used -1 as a workaround
to avoid a NPE on a specific Android TV device. But this is a bug in the
device system, which wrongly assumes that input device may not be null.

A similar issue was present in Flutter, but it is now fixed:
 - <https://github.com/flutter/flutter/issues/30665>
 - <https://github.com/flutter/engine/pull/7986>

On the other hand, using an id of -1 for touchscreen events (which is
invalid) causes issues for some apps:
<https://github.com/Genymobile/scrcpy/issues/2125#issuecomment-790535792>

Therefore, use a device id of 0.

An alternative could be to find an existing device matching the source,
like "adb shell input" does. See getInputDeviceId():
<https://android.googlesource.com/platform/frameworks/base.git/+/master/cmds/input/src/com/android/commands/input/Input.java>

But it seems better to indicate that the event didn't come from a
physical device, and it would not solve #962 anyway, because an Android
TV has no touchscreen.

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.

441d3fb119 Make video buffer more generic

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.

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'
