Now _NEW_PIXEL strictly indicates pixels transfer state changes.

This change avoids framebuffer state validation when any random bit of
pixel-transfer state is set.

DRI drivers updated too:  don't check _NEW_COLOR when updating framebuffer
state.  I think that was just copied from the Xlib driver because we care
about dither enable/disable state there.

Fix symbol list for mangled Mesa on Darwin.

When building mangled Mesa on Darwin, the exported symbols are
named `_mgluWhatever' instead of simply `_gluWhatever'.  When
using a list of exported symbols via the system ld's

this resulted in error messages about exporting symbols which do
not exist.

a wildcard so that the symbol list will match both the mangled and
non-mangled names, preventing the warning and actually exporting
the correct symbols in one shot.

return (0,0,0,1).  Instead of jumping through hoops in all the drivers

texel values.

GPU lockups when trying to sample from missing surfaces.  If a binding
table entry is NULL, it seems that sampling sometimes works, but not
always (lockup).
