The GL based compositing adds alot of complexity and was only ever well
tested on closed stacks. It also only supports GLES3.x and still relies
on sw_sync timeline which is now a debugfs feature. Those are just the
known issues.
Removing the GL compositor means everything related to squashing layers
and pre-compositing can be removed. The planner is left as it may be
useful when adding back support for overlay planes. With this change,
only a single plane is supported until ValidateDisplay learns to do
atomic modesetting test for overlay planes.

When enabling Treble, Android builds are complaining about using
cutils/log.h so instead use log/log.h

Rework the platformdrmgeneric buffer importer to use the libdrm
generic gralloc handle definition.
This is just to get the drm_hwcomposer project building in AOSP
along with the libdrm freedesktop/master branch. Similar changes
may also be needed to gbm_gralloc and other projects not used
in AOSP.
Mostly just sending this out for review feedback.

There's no point in using a gralloc perform() op to retrieve the usage as
it is already stored in the handle like width, height, format, etc. So just
copy it to the hwc_drm_bo_t and get it directly.

Since NV has a "special" nonstandard way to get an EGLImage from a
handle, move this into Importer where the other NV specialness is
abstracted. For the platformdrmgeneric case, use the dmabuf EGL
Extension.

This patch introduces a new Planner interface to the platform specific
code. This new interface will allow for platform-specific plane provisioning
decisions to cover various hardware quirks.
Each platform must provide a Planner with one or more PlanStage steps. These
stages are run in order and are used to move the given layers onto composition
planes.
There are two generic stages provided by the platform:
- Protected: Places layers on dedicated planes
- Greedy: Provisions as many layers to planes and sticks the rest in precomp
There is also one platform-specific stage included:
- ProtectedRotated: Places any protected & rotated layer on the primary plane

Final step in the platform renaming, move the drmgeneric and
nvimporter files to their new place.
