Push weston_coord into the notification functions instead of passing
two doubles.
The touch handlers are passed a pointer to a weston_coord, which is
unusual. This is done so we can pass a NULL pointer instead of a
fabricated invalid coordinate when the touch type is TOUCH_UP.

This fixes the situation where screen share seat is not released upon
compositor shut down.
This will have a cascading side-effecting of resulting in an invalid libinput
device reference assert, like the following:
../src/libinput.c:2169: libinput_device_unref: Assertion
`device->refcount > 0' failed.
That happens because at compositor shutdown, the seat created by the
screen share module will *still* be acccesible in compositor instance
seat list, effectively resulting in an invalid unref for a non-existent
libinput device.
This patch rectifies that in such a way that upon compositor shut down
we release the seat in the screen share module which would implicitly
remove it from the compositor instance seat list.

This sets up monitor layout callbacks, and enables input event translation
between the RDP space and the weston desktop. The RDP backend now uses
a heads changed callback instead of the simple head configurator.
We only allow a single monitor for now, but in the future RAIL will make
use of multi-head.
As a side effect, scaling is now supported in RDP sessions.
It should be noted that due to differences between RDP and wayland
representation of their global coordinate spaces, mixing DPI leads to
RDP monitor layouts that can't properly be represented in weston.

While the --backend parameter looks like it takes a file name, it really
is selected from a list of supported strings that are then funneled
through a translation to enum weston_compositor_backend [1].
Because all backend parameters are of the form "...-backend.so", and
writing "--backend=...-backend.so" is boring, allow the --backend option
to match the backend name without "-backend.so" suffix instead.
For example, this allows to use "--backend=headless" instead of
"--backend=headless-backend.so".
Update help text and documentation. Keep the old way working for
backwards compatibility.

Some monitors expose a selector for the kind of content that will get
displayed, allowing them to optimise their settings for this particular
content type.
I got access to such a monitor, sadly even setting it to game mode
didn’t lower its atrocious latency, but drm_info[1] reports it to be set
correctly so hopefully it’ll work better with other monitors.

This adds basic VNC protocol support using the Neat VNC library
(https://github.com/any1/neatvnc). Neat VNC depends on the AML main
loop library. The backend makes use of AML's integrated epoll backend
and connects AML via file descriptor with the Wayland event loop.
This implementation does not support authentication and hardcodes the
pixel format currently.

As things are, even when mode=current is specified on the .ini file,
a full modeset is needed (and done), which causes a very noticeable
screen blinking. That is because setting the max_bpc on a connector
needs full modesetting.
The idea here is that if mode=current on the .ini, no modesetting
should be done, so the current max_bpc is programmed into the
connector.
But if a custom max-bpc=... is specified, that will be used instead,
even if mode=current on the .ini

The supplied path for executing the shell client could contain potential
arguments and not only the binary itself. Specifying the platform either
by using an argument (-platform wayland) or using an environmental

Everywhere we are standardising to drm_fourcc.h pixel format codes, and
using struct pixel_format_info as a general handle that allows us to
access the equivalent format in various APIs. In the name of
standardisation, convert weston_compositor::read_format to
pixel_format_info.
Pixman formats are defined CPU-endian, while DRM formats are defined
always little-endian. OpenGL has various definitions. Correctly mapping
between these when the CPU is big-endian is an extra chore we can
hopefully offload to pixel-formats.c.
GL-renderer read_format is still defined based on Pixman format, because
of the pecualiar way OpenGL defines a pixel format with
GL_UNSIGNED_BYTE. That matches the same Pixman format on big-endian but
not the same drm_fourcc.

This was using read_format for the read_pixels() call, and then using a
hardcoded format for interpreting the data received from read_pixels().
That works only by accident, read_format being the same as the hardcoded
format.
Use read_format for the interpreting too. This should guarantee the read
pixels are processed correctly.

If we leave xwayland in weston's process group, it can receive
signals from the controlling TTY intended for weston.
The easiest way to see this is to launch weston under gdb, start an
X client, and hit ctrl-c in the gdb session. The Xwayland server
will also catch the SIGINT, and the X client will be disconnected.
Instead, let's call setsid() when launching Xwayland, like we do
for launched clients.

[common equivalent of 77cf8cb006 in Xwayland from Pekka Paalanen; its
commit message follows]
Between fork() and exec() in the child process it is only safe to use
async-signal-safe functions. weston_log() definitely is not one, it
allocates memory and does whatnot.
weston_log() is also inappropriate for other reasons: the child process
has its own stream buffers and flight-recorder. No-one looks into the
child process' flight recorder, so messages would be lost there. The
logging machinery might also attempt to write into debug streams,
meaning both parent and child could be writing simultaneously.
It seems that the best we can do is to pre-bake an error message and
only write() it out if exec() fails. There is no mention that even
strerror_r() might be safe to call, so we don't.
