mesa/vbo: fix compile and replay of nodes ending in a FALLBACK
Where vbo save nodes are terminated with a call to DO_FALLBACK(), as in
the case of a recursive CallList which is itself within a Begin/End pair,
there two problems:
1) The display list node's primitive information was incorrect, stating
the cut-off prim had zero vertices
2) On replay, we would get confused by a primitive that started in a
node, but was terminated by individual opcodes.
This change fixes the first problem by correctly terminating the last
primitive on fallback, and the second by forcing the display list to
use the Loopback path, converting all nodes into immediate-mode rendering.
The loopback fix is a performance hit, but avoiding this would require
a fairly large rework of this code.

mesa/dlist: fixes and improvements for material caching
Only short-circuit material call if *all* statechanges from this call
are cached. Some material calls (eg with FRONT_AND_BACK) change more
than one piece of state -- need to check all of them before returning.
Also, Material calls are legal inside begin/end pairs, so don't need
to be as careful about begin/end state as with regular statechanges
(like ShadeModel) when caching. Take advantage of this and do better
caching.

i965: handle OPCODE_SWZ in the glsl path
glsl compiler will not generate OPCODE_SWZ, and as a first step it would
be translated away to a MOV anyway (why?), but later internally this opcode is
generated (for EXT_texture_swizzling).

Disable SGI_swap_control extension for DRI2
We currently don't have support for SGI_swap_control for direct
contexts with DRI2, so disable reporting the extension. Reporting
the extension, and then having glXSwapIntervalSGI() "succeed"
but do nothing can confuse applications.
