Switch to Mesa master (pre 9.2) - Fix llvmpipe on big-endian and enable llvmpipe everywhere - Build vdpau drivers for r600/radeonsi/nouveau - Enable hardware floating-point texture support - Drop GLESv1, nothing's using it, let's not start

From 5bfa2890c634883260429e7360a3a0367ef47316 Mon Sep 17 00:00:00 2001
From: Adam Jackson <ajax@redhat.com>
Date: Wed, 1 May 2013 13:23:13 -0400
Subject: [PATCH] configure: --enable-texture-float={yes,no,hardware}
This enables building float-texture support for hardware drivers but not
software drivers.
This is obviously not upstreamable in its current form.
