Behdad Esfahbod 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.

Behdad Esfahbod 18c06e189b [Indic] Add Uniscribe bug feature for dotted circle
For dotted-circle independent clusters, Uniscribe does no Reph shaping
for the exact sequence Ra+Halant+25CC.  Which also is the only possible
sequence with 25CC at the end.

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