By doing GC the linker removes all the symbols that are not referenced
and/or used by the final library. This results in a saving of ~100K
up-to ~600K per (stripped) binary (classic vs gallium drivers).
If interested one can ask the compiler to print the sections that are
removed using -Wl,--print-gc-sections.

Neither of them has ever been a part of the API thus there should be

This lets us allocate color buffers as __DRIimages and pass them into
the driver instead of having to create a __DRIbuffer with the flink
that requires.
With this patch, we can now run gbm on render-nodes. A render-node is a
drm device that doesn't support modesetting and all the legacy DRI ioctls.
flink is also not supported, but now that gbm doesn't need flink, we can
run piglit on head-less gbm or head-less GPGPU.

Now that libEGL has been fixed to not leak all kinds of symbols, gbm
links to its own copy of the libwayland-drm.a helper library. That means
we can't rely on comparing the addresses of a static vtable symbol in that
library to determine if a wl_buffer is a wl_drm_buffer. Instead, we
move the vtable into the wl_drm struct and use that for comparing.

We need to create bos suitable for cursor usage that we can map and
write data into. The kms dumb ioctls is all we need for this, so drop
the dependency on libkms.
As discussed with Kristian on #wayland. Pushes the decision of components into
the dri driver giving it greater freedom to allow t to implement YUV samplers
in hardware, and which mode to use.
This interface will also allow drivers like SVGA to implement YUV surfaces
without the need to sub-allocate and instead send 3 seperate buffers for each
channel, currently not implemented.
I have tested these changes on Gallium Svga. Scott tested them on both intel
and Gallium Radeon. Kristan and Pekka tested them on intel.

Uses libkms instead of dri image cursor. Since this is the only user of the
DRI cursor and write interface we can remove cursor surfaces entirely from
the DRI interface and as a consequence also from the Gallium interface as
well. Tho to make everybody happy with this it would probably should add a
kms_bo_write function, but that is probably wise in anyways.
The only downside is that it adds a dependancy on libkms, this could how ever
be replaced with the dumb_bo drm ioctl interface.

This new gbm entry point allows writing data into a gbm bo. The bo has
to be created with the GBM_BO_USE_WRITE flag, and it's only required to
work for GBM_BO_USE_CURSOR_64X64 bos.
The gbm API is designed to be the glue layer between EGL and KMS, but there
was never a mechanism initialize a buffer suitable for use with KMS
hw cursors. The hw cursor bo is typically not compatible with anything EGL
can render to, and thus there's no way to get data into such a bo.
gbm_bo_write() fills that gap while staying out of the efficient
cpu->gpu pixel transfer business.

Pass a dri2_loader extension to the dri driver when gbm creates the dri
screen. The implementation jumps through pointers in the gbm device
so that an EGL on GBM implementation can provide the real implementations.
The idea here is to be able to create an egl window surface from a
gbm_surface. This avoids the need for the surfaceless extension and
lets the EGL platform handle buffer allocation, while keeping the user
in charge of somehow presenting the buffers (using kms page flipping,
for example).
gbm_surface_lock_front_buffer() locks a surface's front buffer and
returns a gbm bo representing it. This bo should later be returned
to the gbm surface using gbm_surface_release_buffer().
To avoid redundancies, this patch also removes .deps, .libs, and *.la
from .gitignore files in subdirectories.

This fixes a build problem where EGL links to libgbm.la, which encodes
a relative path to it's libglapi.so dependency. The relative path
breaks when the linker tries to resolve it from src/egl/main instead
of src/gbm. Typically we silently fall back to the system
libglapi.so, which is wrong and breaks when there isn't one.
Morale of the story: don't mix mklib and libtool.
That is by making the dri extension variables static in gbm_dri.c.
The image_lookup_extension is provided by egl_dri2 when using x11 or wayland
platforms, when using the drm platform, gbm_dri has a wrapper for it.
Both use the same variables name image_lookup_extension.
Since -fvisibility=hidden was (probably by mistake) removed when converting to
automake, the "image_lookup_extension" symbol from egl_dri2.c became exported
in libEGL.so, so "image_lookup_extension" from gbm_dri.c was ignored.
This resulted in calling incorrect callbacks.
We cant make the image_lookup_extension static in egl_dri2.c right now,
since its used across multiple files.

GBM needs the buffer format in order to communicate with DRM and clients
for things like scanout.
So track the DRI format requested in the various back ends and use it to
return the DRI format back to GBM when requested. GBM will then map
this into the GBM surface type (which is in turn based on the DRM fb
format list).
