xf86: add helper functions to convert to from ScrnInfoPtr/ScreenPtr (v2)
These are just simple functions that we should start migrating drivers
to using.
The end goal is to remove xf86Screens and screenInfo from the ABI.
This includes a define XF86_HAS_SCRN_CONV that drivers can ifdef to provide
their own copies. I'll probably post a generic compat.h file for drivers later.
v2: add asserts.
