Unlike the other platforms, here we aim do guess if the device that we
somewhat arbitrarily picked, is supported or not.
In particular: when a vendor is _not_ requested we loop through all
devices, picking the first one which can create a DRI screen.
When a vendor is requested - we use that and do _not_ fall-back to any
other device.
The former seems a bit fiddly, but considering EGL_EXT_explicit_device and
EGL_MESA_query_renderer are MIA, this is the best we can do for the
moment.
With those (proposed) extensions userspace will be able to create a
separate EGL display for each device, query device details and make the
conscious decision which one to use.
v2:
- update droid_open_device_drm_gralloc()
- set the dri2_dpy->fd before using it
- return a EGLBoolean for droid_{probe,open}_device*
- do not warn on droid_load_driver failure (Tomasz)
- plug mem leak on dri2_create_screen failure (Tomasz)
- fixup function name typo (Tomasz, Rob)
v3:
- add forward declaration for droid_load_driver()
Fixes the HAVE_DRM_GRALLOC build (Mauro)
- split dup() assignment and check in separate lines (Tomasz, Eric)
- make droid_load_driver() static (Tomasz)
- drop unused prop_set variable (Tomasz)
v4:
- rebase
- fwd declarationi should be for droid_probe_device()
