[Indic] Apply Indic features
...
Find the base consonant and apply basic Indic features accordingly.
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.

Add prefer_decomposed() complex-shaper callback

This allows the Indic shaper to request decomposed characters. This will
handle split matra for free. Other shapers prefer precomposed
characters.

Let shapers decide when to apply ccmp and locl

Instead of always applying those two features before the complex shaper,
let the complex shaper decide whether they should be applied first.
Also add stub for Indic's final_reordering().

[Indic] Start an Indic shaper
...
Nothing functional in there yet.
So far, we're parsing IndicSyllabicCategory.txt and IndicMatraCategory.txt
fils from Unicode Character Database and store them in an array to be used
by the shaper. Also hooked up the shaper, but it does not do anything
right now.
