Ok, so how about we fix the privates stuff so that drivers can allocate
per-screen private data by sticking a DevPrivateKeyRec inside their
screen private structure? And then we make it so you can allocate
per-screen private data after the server starts, but not other kinds?
I think that'll be pretty straightforward, shouldn't cause performance
regressions in drivers as they generally have a pointer to their screen
private where they're currently using privates.
With that, changing clients to use the serverClient mechanism for
privates (a pointer instead of a directly allocated chunk), and also
using that same scheme for glyphs and we should be able to make this work.
