By labelling devices with ENV{WL_SEAT} in udev rules the devices will be
pulled into multiple weston seats.
As a result you can get multiple independent seats under the DRM and
fbdev backends.
And as a result of this stop iterating through the compositor seat list
(of one item) and instead access the udev_input structure directly.
This enables a refactoring to pull out the weston_seat into a separate
structure permitting multiple seats.
The kernel is supposed to set this when drmModeSetCrtc() is called but
at least the i915 driver wouldn't do that in all cases. A fix for this
should be released with kernel 3.10, but we work around the issue in
older kernels by always forcing DPMS to ON when doing a mode set.

exit() calls atexit() handlers and C++ destructors (e.g. a C++
weston module) which could destroy state that the main process
depends on (e.g. ioctl's, tmpfiles, sockets, etc...). If an exec
fails, call _exit() instead of exit().
v2: prefer _exit over _Exit

The old code had an off-by-one error on the y coordinate
where it says height - (cur_y - y). And it does the vflipping of
the *destination* buffer, whereas what is really needed is to
vflip the whole source buffer. This only affects when you read
out part of the image, such as when using the screen recoder.
Also, instead of doing the flipping manually we just let pixman
handle it.
When a window is fullscreened with DRIVER method and we succeeded
in changing mode we need to actually move the surface to the
origin of the output, or it won't be used for scanout.
Right now we only switch mode on activating a fullscreened window.
This has several problems:
* Once you're in fullscreen its hard to switch to a non-fullscreened
window with alt-tab as you stay in the small resolution.
* If you switch from a fullscreened window to a non-fullscreened
window and the fullscreened window is destroyed we will not
restore the original mode (since the window is not
shell_surface_is_top_fullscreen()
* Its hard to reach a different output on the right with the mouse
when the mode is smaller that the original, as there is a "gap"
between the two outputs. So, if you alt-tab to another window
you can not always reach it.
This is somewhat of a sledge hammer, as it means you can't e.g.
focus a non-fullscreen on one output and have a window fullscreened
on another output. However, trying to restore only the outputs
the new window is on is problematic:
* It may later change output
* We want to see all windows anyway during alt-tab
* Can't reach the other windows with the mouse anyway
So, this seems like an ok solution.
It may happen that you e.g. fullscreen a 800x600 surface with
buffer_scale 1 (e.g. a 800x600 buffer) on an output that is
otherwise scale 2. In this case we want to temporarily set
the output scale to 1, as we're really scanning out of a
scale 1 buffer. This causes us to e.g. report the input
positions in the right place, etc.
When we restore the original mode we also restore the original
scale.
Note that the scale change is a purely compositor internal change,
to clients it still looks like the output is scale 2.
We changed the protocol to always list modes in physical pixel
units (not scaled). And we removed the scaled mode flag. This
just updates the DRM and X11 compositors and the gl and pixman renderers
to handle this.
It was erronously using output->current->height in one
place where it should use output->height. This may cause
it to create an invalid clipped coordinate in case of output
scaling or transform, because the next round "prev" would
end up NULL.
The current config parser, parses the ini file and pulls out the values
specified by the struct config_section passed to parse_config_file() and
then throw the rest away. This means that every place we want to get
info out of the ini file, we have to parse the whole thing again. It's not
a big overhead, but it's also not a convenient API.
This patch adds a parser that parses the ini file to a data structure and
puts that in weston_compositor->config along with API to query comfig
keys from the data structure. The old parser is still available, but
we'll transition to the new approach over the next few commits.
Default output scale of 256 makes little sense. Actually this is a type
mismatch between wl_fixed and int, probably a leftover from when the
scale factor was proposed as a fixed point number.
Scale 256 probably causes the Window creation to fail, but that actually
leads to a segfault in Mesa libEGL later:
Program received signal SIGSEGV, Segmentation fault.

This patch does miscellanous improvements with raw surfaces:
* some frames markers are sent to identify a single frame made of
multiple surface updates
* we send the dirty sub-rectangles instead of the full bouncing box
* the size of the fragmentation buffer is now honored, so that our big
surface updates don't look like a DoS
* the subtile and image flipping are done in one step (not requiring a
temporary tile)
* we don't care about the size of the dirty region and always use the
preferred codec for surface update
Last FreeRDP don't send Synchronize packets anymore, so send the
first screen refresh when we're "connected". The client cursor is
also disabled during this step.
This patch fixes NSC codec initialisation that was not done (an
erronous copy'n paste).
The remoteFx context must be resetted when we go through an activation
sequence
The stream utils of FreeRDP have changed recently, this patch fixes
the compositor compilation against FreeRdp master.
The backend_init() prototype has changed too, this fixes it.
On Raspberry Pi, weston-desktop-shell is so slow to start, that the
compositor has time to run the fade-in before the wallpaper is up. The
user launching Weston sees the screen flipping to black, the fbcon
fading in, and then the desktop popping up.
To fix this, wait for the weston-desktop-shell to draw
everything before starting the initial fade-in. A new request is
added to the private desktop-shell protocol to signal it. If a
desktop-shell client does not support the new request, the fade-in
happens already at bind time.
If weston-desktop-shell crashes, or does not send the 'desktop_ready'
request in 15 seconds, the compositor will fade in anyway. This should
avoid a blocked screen in case weston-desktop-shell malfunction.
shell_fade_startup() does not directly start the fade-in but schedules
an idle callback, so that the compositor can process all pending events
before starting the fade clock. Otherwise (on RPi) we risk skipping part
of the animation. Yes, it is a hack, that should have been done in
window.c and weston-desktop-shell instead.
