7b84c536c1 In MarkBase attachment, only attach to first of a MultipleSubst sequence 
This is apparently what Uniscribe does.  Test case is:

  SEEN FATHA TEH ALEF

with Arabic Typesetting.  Originally reported by Khaled Hosny.

ed2f1363a3 Fix substitution glyph class propagation 
The old code was doing nothing.

Still got to find an example font+string that makes this matter, but
need this for fixing synthetic GDEF anyway.

5df809b655 [GSUB/GPOS] Remove context_length 
The spec doesn't say contextual matching should be done this way,
and AOTS doesn't do it either.  It was inherited from old HarfBuzz.
Remove it.

5f131d3226 [GSUB/GPOS/Indic] Apply GSUB/GPOS within syllables only 
This does not apply to the context matchings.

This regresses tests right now.  And we are not sure whether this is
the right thing to do for GPOS.  But we'll figure out.

41ae674f68 Don't create hb_apply_context_t per glyph! 
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...

651e8dd79e 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.
