V6 address Samuel's comments on v5 (including the ones I missed 
in v4 whoops). I also added some missing error checks for
buffer storage and made a few other tidy-up that I noticed.

There is now so a very basic piglit api error test [1] which
depends on a gl.xml update which is stuck in moderation.
