[Indic] For old-style Indic tables, move Halant around
...
In old-style Indic OT standards, the post-base Halants are moved after
their base. Emulate that by moving first post-base Halant to
post-last-consonant.
Brings test-shape-complex failures down from 88 to 54. Getting there!

[Indic] Apply Indic features

Nothing complete, but does something for now. Specifically:
no Ra handling right now, and no ZWJ/ZWNJ.
Number of failing shape-complex tests goes from 174 down to 125.
Next: reorder matras.

Start cleaning up buffer var allocation
...
I've messed up a lot of stuff recently, different parts of the
shaping process are stumbling on eachother's toes because
manually tracking what's in which buffer var is hard. I'm
going to add some internal API to track those such that mistakes
are discovered as soon as they are introduced.
