[GSUB/GPOS] Remove context_length

The spec doesn't say contextual matching should be done this way,

Remove it.

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...

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.
