i965: Replace OUT_RELOC_FENCED with OUT_RELOC.

On Gen4+, OUT_RELOC_FENCED is equivalent to OUT_RELOC; libdrm silently
ignores the fenced flag:

        /* We never use HW fences for rendering on 965+ */
        if (bufmgr_gem->gen >= 4)
                need_fence = false;

Thanks to Eric for noticing this.

egl_dri2: Remove the unused swap_interval member of dri2_egl_surface

The _EGLSurface struct which is embedded into dri2_egl_surface also contains a

dri megadriver_stub: add compatibility for older DRI loaders

To help the transition period when DRI loaders are being updated
to support the newer __driDriverExtensions_foo mechanism,
we populate __driDriverExtensions with the extensions returned
by __driDriverExtensions_foo during a library contructor
function.

We find the driver foo's name by using the dladdr function
which gives the path of the dynamic library's name that
was being loaded.

nv50: report 15 max inputs for fragment programs

First off, nv50_program only has 16 in/out varyings. However reporting
16 makes 'm' become 68 in nv50_fp_linkage_validate with the
varying-packing-simple piglit test. (Subverting the assert makes it
compile but fail.) With this patch, varying-packing-simple passes.

draw: fix vbuf caching of vertices with inject front face

Caching in the vbuf module meant that once a vertex has been
emitted it was cached, but it's possible for a vertex at the
same location to be emitted again, but this time with a different
front-face semantic. Caching was causing the first version of the
vertex to be emitted, which resulted in the renderer getting
incorrect front-face attributes. By reseting the vertex_id (which
is used for caching) we make sure that once a front-face info
has been injected the vertex will endup getting emitted.
