Subject: {st,targets}/dri: use static/dynamic pipe-loader
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=23fb11455b4;p=mesa.git

{st,targets}/dri: use static/dynamic pipe-loader

Covert DRI to use only the pipe-loader interface.

With drisw_create_screen and kms_swrast_create_screen replaced by their
pipe-loader equivalent, we can now drop them.
