Bug Description

There is a bugfix in 10.3.1 that will fix dma-buf handling in i915. So we would like to see the newest minor release of mesa, which is 10.3.1 This will fix: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1275398 and basically enable i915 devices to run mir.

[Impact]

 * The bug leads to crashes in unity8 on i915 and to crashes or 'black buffers' on mir clients.

 * This is not a request for back porting but a request to pick the next minor bugfix release of mesa.

[Test Case]

 * Install mir-demos on a intel atom netbook or a pentium d system
 * sudo mir_demo_server_basic --vt 2 --file /tmp/mir_socket
 * sudo chmod 666 /tmp/mir_socket
 * mir_demo_client_egltriangle -m /tmp/mir_socket
 * then vt switch to vt 1
 Expected: Animation
 Observed: Crashing or just showing a black buffer

[Regression Potential]

 * Instead of immediately crashing unity8s desktop session it will make the primary client of unity8: unity8-dash fail to start due to insufficient GL support on the mesa driver - but that is a different error.

 * 10.3.1 introduces the bespoke i915 bug fix, and further driver local fixes to nouveau for the kepler ir, shutdown leak fixes for radeon and a division by zero fix for llvmpipe. A fix to glsl that first manifested in i965. Apart from that build system cleanups for building mesa for android and detecting LLVM.
 * the fix to glsl has impact on i965
 * fixes for intel are local to i915 and will not cause regression
 * fixes to radeon should only touch shutdown code
 * fixes to nouveau should be local to kepler gpus

[Other Info]

 * The switch to this mesa release will not enable mir. But it will not enable unity8 on pentium D and atom, but it will be a step towards that

Removed mention of eglplasma and changed it to egltriangle. I think eglplasma has separate bugs that prevent it from working on i915.
