We move the EGL and GLES2 output repaint code into a new gles2-render.c
file. The eglMakeCurrent, glViewPort, surface loop etc was duplicated
across all backends, but this patch moves it to a new file.
Draw the borders of all the triangles.
v1: original
v2: add keybinding to enable/disable fan debug (super-alt-space),
cycle colors to make it easier to see individual draws, and
redraw undamaged region to clean up previous frames debug

Re-work how the shaders and emitted vertices work. Rather than always
rendering clip-rect sized quads and doing transformation in tex coords
(and requiring the corresponding clipping in frag shader), instead
emit transformed vertices, clipped wrt. dirty region, and use simpler
frag shaders. Also, split the rendering, so blended surfaces with an
opaque region have the opaque region drawn with blend disabled. The
result is considerably fewer pixels drawn with blend enabled, and much
fewer cycles in the frag shader.
This requires having some more complex logic to figure out the vertices
of the shape which forms the intersection of the clip rect and the
transformed surface. Which has perhaps got a few bugs or missing cases,
still (visual glitches in some cases) but at this point more or less is
starting to work. I think it is at least far enough along to get some
initial review.
The result, on small SoC GPU (omap4/pandaboard) on 1920x1080 display,
for simple stuff like moving windows around, I get 60fps (before 30fps
or less), and pushing YUV buffers for hw decoded 1080p video goes from
~6fps to 30fps, with no drop in framerate for transformed/rotated video
surface.
v1: original
v2: check that perpendicular intersect vertex falls within bounds of
transformed surface
v3: update w/ comments and fixes from Pekka Paalanen
v4: fix for full surface alpha from Pekka Paalanen, fix compositor-
wayland build

This patch allows rotation and mirroring outputs for x11 and drm backends.
A new 'transform' key can be set in the [output] section. From the protocol:
"The flipped values correspond to an initial flip around a vertical axis
followed by rotation."
The transform key can be one of the following 8 strings:
normal
90
180
270
flipped
flipped-90
flipped-180
flipped-270
We don't want to send enter/leave events to the compositor when the pointer
enters the surface, only when the pointer enters the content area. This
avoids hiding the cursor when entering the frame and sending out-of-bounds
coordinates to notify_pointer_focus().
When we hit a segv, it's often the case that we might crash again in
the attempt to clean up. Instead we introduce a minimal restore callback
in the backend abstraction, that shuts down as simply as possible. Then
we can call that from the segv handler, and then to aid debugging, we
raise SIGTRAP in the segv handler. This lets us run gdb on weston from
a different vt, and if we tell gdb
(gdb) handle SIGSEGV nostop
gdb won't stop when the segv happens but let weston clean up and switch vt,
and then stop when SIGTRAP is raised.
It's also possible to just let gdb catch the segv, and then use sysrq+k
followed by manual vt switch to get back.
Simplify RGB shader code and split off common code that could be reused.
This is preparatory work for YUV shaders.

weston_compositor_init is always called late because most
implementations can't initialise GL until fairly late in the game.
Split it into a base version with the same name, followed by
weston_compositor_init_gl which can be called later on.
This simplifies compositor-wayland, which no longer needs a separate
global handler just for wl_seat.

Use the wl_keyboard::modifiers events our parent helpfully sends us to
make sure our views of the keyboard state are always identical, rather
than relying on key press events to do the right thing.

If update_state is true, then notify_key will continue to call
xkb_key_update_state to update the local state mask, as before this
commit. Otherwise, it will rely on the compositor to manually update
the state itself, for nested compositors.

EGLDisplay is helpfully typedeffed as void *, which means that you won't
get conflicting-pointer-type warnings if you accidentally confuse it
with weston_compositor::wl_display. Rename it to make it more clear
which display you're dealing with, and also rename compositor-wayland's
parent.display member to parent.wl_display.

We'll get a rash of seats added when we run our first wl_display_iterate
across the parent display, but won't actually be ready to create them.
Create a new global listener on our parent display for wl_seats only,
and run that from wayland_input_create.

These keymap events communicate the keymap from the compositor to the
clients via fd passing, rather than having the clients separately
compile a map.

This allows backends to generate their own keymaps and pass them in for
use rather than always forcing a single global keymap, which is
particularly useful for nested compositors.

Instead of using a uint32_t for state everywhere (except on the wire,
where that's still the call signature), use the new
wl_keyboard_key_state enum, and explicit comparisons.

This event lets the compositor inform clients of the canonical keyboard
modifier/group state. Make sure we send it at appropriate moments from
the compositor, and listen for it in clients as well.

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.

Switching display mode may happen when:
1. The fullscreen surface is at top most in fullscreen layer and with
"driver" method. Shell will switch output mode to match the surface
size. If no matched mode found, fall back to "fill" method.
2. The top fullscreen surface is destroyed or unset. Switch back to the
origin mode.
