Make it an error to include non-top-level headers

Users should #include <hb.h> (or hb-ft.h, hb-glib.h, etc), but
never things like hb-shape.h directly. This makes it easier to
refactor headers later on without breaking compatibility.

[hangul] Apply *jmo features to all Hangul chars

This is what old HB does. Morever, fixes rendering with Win8 malgun

but Win8 version works as expected, like Uniscribe, with this change.

I couldn't measure significant performance gains out of this; maybe
about 5% (with one million Malayalam strings). Still, not bad.
But reminds me that optimizing this codebase without profiling first
is simply not going to work. Oh well...

Add simple Hangul shaper that recomposes Jamo when feasible
...
Previously, we were NOT actually recomposing Hangul Jamo. We do now.
The two lines in:
test/shaping/texts/in-tree/shaper-default/script-hangul/misc/misc.txt
Now render the same with the UnDotum.ttf font. Previously the second
linle was rendering boxes.
We can also start applying OpenType Jamo features later. At this time,
I have no idea how the 'ljmo', 'vjmo', 'tjmo' features are supposed to
work. Maybe someone can explain them to me?
