[RFC] [PATCH] i965: better ClientWaitSync

[Ben Widawsky <ben@bwidawsk.net>]

Use the new libdrm functionality to actually do timed waits on the sync
object.

This patch is missing the configure.ac update to check for the correct
libdrm supporting this function. As of now, libdrm has not yet received
the version bump. That's mostly why this patch is "RFC"

Since intel_client_wait_sync function previously had no way of reporting
back the errors/timeouts, and I do not have a good test case anyway,
I've decided to not worry about this also.
