os: macro for marking struct fields xserver-internal 

Several drivers still accessing internal struct field they shouldn't,
eg. directly calling or manipulating low level proc vectors, while
there are higher level functions for that.

Introducing a macro for marking struct fields internal, so the compiler
spits out a deprecation warning when those are accessed by drivers
directly.
