Calling wl_list_init just before wl_list_insert is redundant. Because

This bug was introduced in 954f183e2f.
The session_notify() data was accidentally cast to fbdev_backend while
it is weston_compositor. This was possibly due to the code before the
mentioned commit casting data directly to fbdev_compositor without going
through the intended type first, which worked only because
weston_compositor was the first member in struct fbdev_compositor.
Fix the casts to be the right way around.

The buildbots discovered this issue on Ubuntu 14.04, which carries
libgbm 10.1.3-0ubuntu0.4. The dmabuf changes need gbm 10.2, so it fails
during build like this:
src/compositor-drm.c: In function ‘drm_output_prepare_overlay_view’:
src/compositor-drm.c:984:10: error: variable ‘gbm_dmabuf’ has
initializer but incomplete type
struct gbm_import_fd_data gbm_dmabuf = {

etc.
Proposed fix is to conditionalize the gbm fd import feature in
compositor-drm.
This fix was suggested by daniels. I set up a synthetic test
environment to reproduce the issue as found by the buildbots and tweaked
the patch to get it to build both with and without gbm 10.2.

Import dmabuf as an EGLImage, and hold on to the EGLImage until we are
signalled a content change. On content change, destroy the EGLImage and
re-import to trigger GPU cache flushes.
We hold on to the EGLImage as long as possible just in case the client
does other imports that might later make re-importing fail.
As dmabuf protocol uses drm_fourcc codes, we need libdrm for
drm_fourcc.h. However, we are not doing any libdrm function calls, so
there is no new need to link to libdrm.
RFCv1 changes:
- fix error if dmabuf exposed unsupported
- always use GL_TEXTURE_EXTERNAL_OES with dmabuf

An experimental (hence the 'z' prefix) linux_dmabuf Wayland protocol
extension for creating dmabuf-based wl_buffers in a generic manner.
This does not include proper dmabuf metadata negotiation because
there is no way to communicate all dmabuf constraints from the
compositor to a client before-hand. The client has to create a
wl_buffer wrapping one or more dmabuf buffers and then listen at
the feedback object returned to know if the operation was successful.
RFCv1 changes (after a first draft without code):
- some renames of interfaces and argument, no semantic changes
- added destructor protocol to dmabuf_batch
- added feedback interface for buffer creation
v2 changes:
- use drm_fourcc.h as authoritative source for format codes
- add support for the 64-bit layout qualifier and y-inverted dmabufs
- simplify the 'add' request (no need to preserve fd numerical id)
- add explicit plane index in the 'add' request
- integrate the 'feedback' object events to the batch interface
- rename 'create_buffer' to 'create' and move it into the batch interface
- add requirements needed from the graphics stack and clients
- improve existing errors and add batch error codes
- removed error codes from the global interface
- improve documentation for arguments, enums, etc.
- rename dmabuf_batch to zlinux_buffer_params
- The y-inverted property makes more sense as a whole buffer property.
Y-flipping individual planes of the same buffer object is hardly useful.
The y-invert is also converted into a flag, so we may add more flags
later.
- add flags for interlaced buffer content
v3 changes:
- Apply Daniel Vetter's comments about wording on coherency.

Valgrind has shown that in at least one place (default_grab_pointer_focus)
we're testing uninitialized values coming out of weston_compositor_pick_view.
This is happening when default_grab_pointer_focus is called when there is
nothing on the view list, and during the first repaint when only the black
surface with no input region exists.
This patch adds a function to clear pointer focus and also set the sx,sy
co-ordinates to a sentinel value we shouldn't compute with.
Assertions are added to make sure any time pointer focus is set to NULL
these values are used.
weston_compositor_pick_view() now returns these values too.
Now the values are always initialized, even when no view exists, and
they're initialized in such a way that actually doing computation
with them should fail in an obvious way, but we can compare them
safely for equality.

When something goes wrong during weston initialization,
weston_compositor_destroy() is executed. It destroys the backend and
then frees compositor memory. Unfortunately RDP backend is not correctly
destroyed. It frees compositor instead of a backend memory. This causes
later a double free error. The easiest way to reproduce a problem is to
run weston with an invalid option.
Additionally some other objects of rdp_backend structure are not
destroyed/freed. The patch fixes both issues.
