fd_import support for gbm/mesa < 17.1.

56d1f4e7bc backend-drm: Fix for gbm modifiers when they are not available.
When the HAVE_GBM_MODIFIERS is unset, make the code drop back
to a single plane version like other places in the code.

ccf24076dd backend-drm: make GBM optional
Make GBM optional in case GL renderer is disabled. This allows to
build Weston with DRM backend without Mesa dependencies.

d32dfcf833 backend-drm: Enforce content protection for hardware planes
62626cbfec ensures that the GL render will not render a view's content
to the screen when the surface has requested a higher content-protection
level than the output currently offers.

When the HDCP MR was split into the core content-protection support in !83
and specific DRM support for HDCP in !48 (not yet landed), this opened a
hole where the DRM backend could promote a view to a hardware plane,
even if the output offered a lower protection level than the surface
wanted to enforce.

In the DRM backend, check the desired protection level, and refuse to
promote the view to a hardware plane if the output does not offer
sufficient protection. This will lead to presentation falling back to
the renderer, which may censor the content, reduce quality, etc.

5dd3e9996a backend-drm: drop gbm.h from c files
The header file is anyway included in drm-internal.h, we can safely
drop it from the c files.
