The patch looks good to me, it makes AIGLX behave properly wrt
advertised extensions.  Only comment is that for now, GLX_EXT_tfp is
entirely implemented in glxdri.c and thus always available, so the 'N'
should be changed to 'Y' instead.  Even when we later on gain driver
support for this, we will still keep the generic implementation
around, so 'Y' makes sense now and later.

On a side note, I'd really like to get rid of all the unsued swap
barrier stub code.  Any objections?  We can add it back in a way that
sits better with the new structure of the GLX module if we need it.
