From draft update to USE.

This makes USE feature-complete as far as the Indic-like features
are concerned.

The spec wrongly has "H" where "HN" is meant.

Grammar from the spec!

Initial setup of gtk-doc. Straight forward setup following the gtk-doc
instructions. Ignore some troublesome types in src/hb-gobject.h. To
build use "./autogen.sh --enable-gtk-doc" then "make". Docs are in
harfbuzz/docs/reference/html/index.html.

Adds check-valgrind among other modes.  We do not run under gtester by
default anymore.
