Mesa 18.1.7 Released With Few Bug Fixes

Mesa 18.1.7 ships with the last two weeks worth of fixes in the Mesa stable space. But overall this isn't nearly as big as past Mesa 18.1 point releases. Mesa 18.1.7 has some minor fixes to R600 Gallium3D, Intel i965, RADV Vulkan driver fixes, the Doom workaround has been back-ported to RADV, and a variety of other fixes.'..
