Add libgralloc_drm library to export headers to mesa

Mesa mainline depends on libgralloc_drm shared library for importing
include paths. Add a dummy library for this purpose. This gets mesa master
building without any additional patches. Patches are still needed for
proper functioning.

Fix missing 0 init of alloc_device_t

This fixes a crash of "dumpsys SurfaceFlinger" because the dump() pointer

gbm_gralloc: Remove the invalid int cast and assignment in gbm_mod_perform()

In gbm_mod_perform(), for the cmd GRALLOC_MODULE_PERFORM_GET_USAGE,
the code takes the third argument, casts it as an int* and then writes
a zero into what the pointer points to.

The problem with this is that the third argument to that function is
actually a native_handle_t, so writing zero to the first int in that
structure ends up overwriting the version value, causing the
native_handle_t code to see the value as corrupt.

This results in lots of warnings and leaked fds.

Change module name to gralloc.gbm

Originally, the intent was to make GBM gralloc a drop-in replacement for
DRM gralloc, but this isn't really happening or needed. Change the name
so both can coexist.

Fix mapping for non-zero starting coordinates

While the gralloc API allows for specifying the starting coordinates (L,T),
it seems this doesn't really work. No other gralloc implementations found
use the rectangle bounds. Not exactly sure how this ever worked, but it
broke recently with AOSP master.

Add YV12 pixel format support

GBM doesn't support YV12 and we need a single buffer, so request GR88 from
GBM instead and adjust the width and height. GR88 also ensures (hopefully)
that the GPU texture alignment requirements are met.
