Subject: Convert driCreateScreen and driDestroyScreen to function pointers.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a1ea6f6198d80f716936a308cfab235f18a014e1;p=mesa.git

Convert driCreateScreen and driDestroyScreen to function pointers.

We avoid leaking the symbols and will be able to replace them with
DRI2 implementation later on.
