shell: remove remnants of screensaver surface list

The list became stale probably when the lock_layer was introduced. Now
one less (ab)user of weston_surface::link.

Also add a comment on screensaver_configure(), that it is (and has been)
broken for pre-started screensavers.

tests: make signal other than ABRT a hard failure

We handle FAIL_TEST tests by simply inverting the success flag. The
problem with this is, that if a FAIL_TEST fails by a SIGSEGV, it will be
interpreted as passed. However, no code should ever cause a SEGV, or any
other signal than ABRT. And even ABRT only in the case of an assert()
that is meant to fail. We would probably need more sophistication for the
FAIL_TEST cases.

For now, just interpret any other signal than ABRT as a hard failure,
regardless whether it is a TEST or FAIL_TEST. At least segfaults do not
cause false passes anymore.

compositor: remove android backend

The Android backend has been fairly unused, since we do not have
projects actively using it. It gets basic build testing as part of the
normal build, but runtime testing it takes a considerable effort, and so
I have not done that in a long time. The code is slowly rotting, and
with new emerging backends it starts to be a burden, since it cannot use
udev, but needs evdev.

Therefore to ease Weston going forward, remove the Android backend. If
someone misses it, it can still be found in the stable 1.0 branch, and
of course resurrected from git history if someone wants to put in the
effort and maintain it.

configure: remove C++ support

With the Android backend gone, there is no C++ code anymore. Remove
support for C++ in the build.

weston-launch: Use "weston-launch" for --help instead of "weston".

The output of weston-launch --help was "Usage: weston [args...] ...".
This changes it to read "Usage: weston-launch [args...] ...".
clients: add global_remove handler stubs

All the clients here were missing the global_remove handler. Because
window.c did not have it, weston-desktop-shell and weston-keyboard
segfaulted on compositor exit, as they received some
wl_registry.global_remove events.

Add more or less stub global_remove handlers, so that clients do not
crash on such events. Toytoolkit and all applications would need a lot
more code to properly handle the global object removal.

Weston: weston.ini.man page

changes:
 - launcher path, passing environment variables and parameter
 - indent modeline example
pixman-renderer: Add repaint debugging feature

Add 'R' as a debug shortcut that highlights repainted regions.
pixman-renderer: Move shadow buffer into renderer

The X11 backend uses a shadow buffer to be able to support transformed
outputs. However, this belongs in the renderer, since otherwise this
code would have to be copied into every backend that uses the pixman
renderer and supports transformed outputs.
compositor-drm: Split kms initialization out of init_egl()
compositor-drm: Put logic of destroy/releasing bo's in its own function

We have this duplicated in a few places.
compositor-drm: Support creating drm_fb backed by dumb buffers
compositor-drm: Add support for using the pixman renderer

If --use-pixman is passed as command line option to weston, the drm
backend will use the pixman renderer instead of the gl one.
pixman-renderer: Don't unreference NULL hw_buffer image

If the buffer for an output was never set, or was reset to NULL at some
point, destroying the renderer output private would cause a crash.
terminal: Handle the window close event

There may be multiple windows open, so destroy the terminal instead of exiting.

clients: Make libtoytoolkit a libtool library

This way libtool will remember the libtoytoolkit LIBADD libraries.
We can drop the toolkit_libs hack and just link to libtoytoolkit.la and
libtool will add the dependencies.
Add new shared/image-loader.h to separate include dependencies

Before, cairo-util.h would combine pixman and cairo includes.  X11 and
Wayland compositors uses this to load an image as a pixman_image_t but are
forced to include cairo headers.  Clients use load_cairo_surface to
load images as cairo_surface_t's, but are forced to include pixman.h.

We move the load_image pixman prototype to its own header, so compositors
can get at the pixman prototype without including cairo.h and clients
can include the cairo based function without including pixman.h.
toytoolkit: Remove left-over pixman dependency

toytoolkit doesn't use pixman.  Remove the pixman.h include and the
LDADD.

matrix: track transform type

Introduce several matrix transform types and track type for matrix.
Could be usefull for activating some fastpath that depends on some
transform type.
