The FFmpeg dependency is downloaded from two separate zipfiles.
Symlink include/ to expose everything from a single directory, to
simplify the meson script.
PR #2952 <https://github.com/Genymobile/scrcpy/pull/2952>
The fact that the current prebuilt FFmpeg is split into two separate
zipfiles is an implementation detail.
Use a single Makefile recipe for both files.

The components should be configurable independently of the global
scrcpy_options instance: their configuration could be provided
separately, like it is the case for example for some screen parameters.
For consistency, keyboard injection should not depend on scrcpy_options.
In relative mouse mode, the mouse pointer must be "captured" from the
computer.
Toggle (disable/enable) relative mouse mode using any of the hardcoded
capture keys:
- left-Alt
- left-Super
- right-Super
These capture keys do not conflict with shortcuts, since a shortcut is
always a combination of the MOD key and some other key, while the
capture key triggers an action only if it is pressed and released alone.
The relative mouse mode is also automatically enabled on any click in
the window, and automatically disabled on focus lost (it is possible to
lose focus even without the mouse).
The decision to not send motion events when no click is pressed is
specific to Android mouse injection. Other mouse processors (e.g. for
HID mouse) will need to receive all events.
The default mouse injection works in absolute mode: it forwards clicks
at a specific position on screen.
To support HID mouse, add a flag to indicate that the mouse processor
works in relative mode: it forwards mouse motion vectors, without any
absolute reference to the screen.
A scroll event might be produced when a mouse button is pressed (for
example when scrolling while selecting a text). For consistency, pass
the actual buttons state (instead of 0).
In practice, it seems that this use case does not work properly with
Android event injection, but it will work with HID mouse.
The input_manager is strongly tied to the screen, it could not work
independently of the specific screen implementation.
To implement a user-friendly HID mouse behavior, some SDL events
will need to be handled both by the screen and by the input manager. For
example, a click must typically be handled by the input_manager so that
it is forwarded to the device, but in HID mouse mode, the first click
should be handled by the screen to capture the mouse (enable relative
mouse mode).
Make the input_manager a descendant of the screen, so that the screen
decides what to do on SDL events.
Concretely, replace this structure hierarchy:
+- struct scrcpy
+- struct input_manager
+- struct screen
by this one:
+- struct scrcpy
+- struct screen
+- struct input_manager
This avoids to directly pass the options instance (which contains more
data than strictly necessary), and limit the number of parameters for
the init function.
Not all key processors support text injection (HID keyboard does not
support it).
Instead of providing a dummy op function, set it to NULL and check on
the caller side before calling it.
Pass scrcpy input events instead of SDL input events to mouse
processors.
These events represent exactly what mouse processors need, abstracted
from any visual orientation and scaling applied on the SDL window.
This makes the mouse processors independent of the "screen" instance,
and the implementation source code independent of the SDL API.
This aims to make the key/mouse processors independent of the "screen",
by processing scrcpy-specific input events instead of SDL events.
In particular, these scrcpy events are not impacted by any UI window
scaling or rotation (contrary to SDL events).
The input manager exposed functions taking an "actions" parameter,
containing a bitmask-OR of ACTION_UP and ACTION_DOWN.
But they are never called with both actions simultaneously anymore, so
simplify.

This allows to report a meaningful error message if an unsupported
feature is used on an incompatible platform. This is consistent with the
behavior of -K/--hid-keyboard.
The "resize to fit" feature (MOD+w or double-click on black borders)
computed the "optimal size" using the same function computing the
initial window size on start.
However, on "resize to fit", only the black borders must be removed (the
content size must be preserved), so the display bounds must not be
considered.
