i965: fix problem with constant out of bounds access (v3)
Okay I now understand why Frank would want to run away, this is
my attempt at fixing the CVE out of bounds access to constants
outside the range. This attempt converts any illegal constants
to constant 0 as per the GL spec, and is undefined behaviour.
A future patch should add some debug for users to find this out,
but this needs to be backported to stable branches.
CVE-2013-1872
v2: drop the last hunk which was a separate fix (now in master).
hopefully fix the indentations.
v3: don't fail piglit, the whole 8/16 dispatch stuff was over
my head, and I spent a while figuring it out, but this one is
definitely safe, one piglit pass extra on my Ironlake.
NOTE: This is a candidate for stable branches.

configure.ac: Build dricommon for gallium swrast
When building dri-swrast, use gallium_check_st to set HAVE_COMMON_DRI.
Commit 07f2dee7 added setting of HAVE_COMMON_DRI in gallium_check_st.
But the dri-swrast case did not use gallium_check_st.
So dri/common was still not built.
v2: set HAVE_COMMON_DRI=yes instead of using gallium_check_st
NOTE: This is a candidate for the 9.1 branch.
(Depends on 7de78ce5 and 07f2dee)

configure.ac: Build dricommon for DRI gallium drivers
Commit 67ef7559 added an || test "x$enable_dri" check in an attempt to
get the DRI common bits built in some necessary cases. That change was
inappropriate as it made these common DRI pieces be built
unconditionally, so some builds were broken.
Subsequently, commit 998d975e3 change the "|| test" to a "-a"
conjunction within the existing test invocation. This made the '-a
"x$enable_dri" = xyes' clause have no effect, (as it was inside an
enclosing test for the same condition). So the new breakage from
commit 67ef7559 was addressed, but the original problems were
regressed.
The immediately preceding commit removed the redundant condition.
Now, finally this commit fixes the original problem as described in
the commit message of 67ef7559: this code should be compiled when
using the DRI state tracker. In order to do so, the HAVE_*_DRI
conditionals must be moved after the last assignment of HAVE_COMMON_DRI.
