Summary:
Currently there is no any good reason for keeping ScopedDrmPointer;
providing our own deleter for QScopedPointer would make more sense.
Given that we already have type that acts as a scoped pointer for drm
objects we can improve it a bit and make simpler, e.g.
DrmScopedPointer<drmModeConnector> connector;
is much simpler than
ScopedDrmPointer<_drmModeConnector, &drmModeFreeConnector> connector;
