[RFC][PATCH v2] drm_hwcomposer: Rework platformdrmgeneric.cpp to use libdrm's gralloc handle

[John Stultz <john.stultz@linaro.org>]

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.
