    st/mesa: initialize all program constants and UBO limits
    Also simplify UBO support checking.
    NOTE: This is a candidate for the 9.1 branch.

mesa: fc25956badb8e1932cc19d8c97b4be16e92dfc65 (master 10.2.0-devel)

arb_uniform_buffer_object-maxuniformblocksize fs passes on softpipe now but still fails on llvmpipe.

Seems to work here now.
