swrast: Remove the classic swrast DRI driver
Following up from the classic swrast OSMesa removal in favor of llvmpipe/softpipe, remove the classic swrast DRI driver. It's unused by any distribution -- debian was the last holdout until this week, which had it enabled instead of softpipe on obscure platforms (non-LLVM and hurd). Now that debian has switched, remove the driver so nobody can accidentally enable it again. Fixes: #325, #324, #322, #321, #319, #318, #317, #315, #313, #311, #310, #306, #305, #304, #302, #301, #300, #299, #298, #297, #293, #289 Reviewed-by: Eric Anholt <eric@anholt.net> (commit message rewritten) Reviewed-by: Matt Turner <mattst88@gmail.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/8069>
