On receiving an "inject touch" control message, update the local
pointers state and inject touches.

Add a control message type in the protocol to forward touch events to
the device.

This will help to distinguish them from "touch pointers".

Add a function to write 64 bits in big-endian from a uint64_t.

Rename "XXX_from_sdl_to_android" to "convert_XXX", to avoid huge
function names.

The filename gave no hint about what was converted.

Some variable names had not been renamed when "event" was renamed to
"message" (28980bbc).

The mouse event test actually tested a key event control message.

The AVPacket fields side_data and side_data_elems were not initialized
by av_packet_ref() in old FFmpeg versions (prior to [1]).

As a consequence, on av_packet_unref(), side_data was freed, causing a
segfault.

Enable the attribute "console" of custom_target() introduced in meson
0.48. This allows to get a feedback of what gradle does (which can takes
a very long time).

This produces warnings because we declare to support meson >= 0.37, but
we don't want to stop supporting older versions for that. Older versions
just ignore the option:

> WARNING: Unknown keyword arguments in target scrcpy-server: console

Newer meson versions use it, but warn because we declare supporting
older versions:

> WARNING: Project targetting '>= 0.37' but tried to use feature
> introduced in '0.48.0': console arg in custom_target

Meson does not support conditional branches to suppress such warnings,
so just keep the warnings.

Update WindowManager.java

Record a packet only once the following has been received, so that we
can set its duration before muxing it.

Fix building on OS X (missing NULL in queue.h)

Headers seem to be a bit different in Apple land and you need to include
stddef.h explicitly to the NULL declaration.

This also makes the code a bit more correct, as stddef.h is the header
in the C standard that defines NULL
(https://en.cppreference.com/w/cpp/header/cstddef).

They were listed in the blog post introducing scrcpy:
<https://blog.rom1v.com/2018/03/introducing-scrcpy/>

Include the latest version of SDL in Windows releases.

Include the latest version of adb in Windows releases.

Include the latest version of FFmpeg in Windows releases.

The compiler is not always able to see that "last" is always initialized
before being used, so always initialize it.

Replace the specific recording queue by the new generic FIFO queue
implementation.

We need several FIFO queues (a queue of packets, a queue of messages,
etc.).

Some of them are implemented using cbuf, a generic circular buffer. But
for recording, we need to store the packets in an unbounded queue until
they are written, so the queue was implemented manually.

Create a generic implementation (using macros) to avoid reimplementing
it every time.

Put the scrcpy files at the root of the zip archive. This avoids an
unnecessary level of directories when extracting.

If recording fails, log "recording failed" instead of "recording
complete".

Keep --version which also print the version of dependencies.
