[Qemu-devel] [PULL 1/5] ui: use libexpoxy

[Gerd Hoffmann]

libepoxy does the opengl extension handling for us.

It also is helpful for trouble-shooting as it prints nice error messages
instead of silently failing or segfaulting in case we do something
wrong, like using gl commands not supported by the current context.
