We need to initialize prev when we handle the initial pixel in a
rectangle, or we may detect the following pixel as identical or different
when it's not. This causes the top-left pixel in a rectangle to
occasionally be wrong leaving a trail of "dirty pixels" in the capture.
This is the point where we have just finished rendering the new scene
but before we swap it to the front buffer. At this point, the
output->previous_damage region exactly corresponds to what was just
renders, as compared to previous frame.
This commit adds a new, built-in screen recorder tool. The tool UI is
still very simple, start with mod-r and stop it again with mod-r.
The recording is written to capture.wcap, in a simple run-length encoded
adhoc format. The wcap-decode tool can be used to extract a single frame
from the capture, for now, but the plan is to hook this up to libvpx and
generate webm output.
wl_input_device has been both renamed and split. wl_seat is now a
virtual object representing a group of logically related input devices
with related focus.
It now only generates one event: to let clients know that it has new
capabilities. It takes requests which hand back objects for the
wl_pointer, wl_keyboard and wl_touch interfaces it exposes which all
provide the old input interface, just under different names.
This commit tracks these changes in weston and the clients, as well as
similar renames (e.g. weston_input_device -> weston_seat). Some other
changes were necessary, e.g. renaming the name for the visible mouse
sprite from 'pointer' to 'cursor' so as to not conflict.
For simplicity, every seat is always exposed with all three interfaces,
although this will change as time goes on.

Some GL implementations do not provide GL_EXT_read_format_bgra
extension.
Set a glReadPixels format based on whether the extensions is supported
or not, and use that format in all backends.
Add RGBA->BGRA swapping copy to screenshooter to keep the shm buffer
data format as BGRA.

This rename addresses a few problems around the split between core
Wayland and the wayland-demos repository.
1) Initially, we had one big repository with protocol code, sample
compositor and sample clients. We split that repository to make it
possible to implement the protocol without pulling in the sample/demo
code. At this point, the compositor is more than just a "demo" and
wayland-demos doesn't send the right message. The sample compositor
is a useful, self-contained project in it's own right, and we want to
move away from the "demos" label.
2) Another problem is that the wayland-demos compositor is often
called "the wayland compsitor", but it's really just one possible
compositor. Existing X11 compositors are expected to add Wayland
support and then gradually phase out/modularize the X11 support, for
example. Conversely, it's hard to talk about the wayland-demos
compositor specifically as opposed to, eg, the wayland protocol or a
wayland compositor in general.
We are also renaming the repo to weston, and the compositor
subdirectory to src/, to emphasize that the main "output" is the
compositor.
Nothing was freeing the allocation from screenshooter_create().
Add enough boilerplate, that we can free it. Fixes a Valgrind leak.
