24264cb7f8 [subset] Fix chaos handling to be more inclusive 
If a contextual lookup recurses twice on the same index, that index
most be marked chaotic for the second recursion.

Also, when a non-1-to-1 recursion happens, only mark glyph locations
after current to be chaotic, not everything.

I believe this fixes a bug that before we were not inclusive enough.
Now we might have introduced more false positives, but we are at least
correct.

22ffbba4b7 [subset] Further narrow down cur_glyphs in recursive contextuals 
Improves NotoNastaliqDraft closure_glyphs() time from 60s to 50s.

This was originally introduced in 1d4fa13b4.  I'm fairly confident
new code is correct.

c4d0400004 [subset] Speed up closure_glyphs() a bit 
Was taking nine minutes on NotoNastaliqUrdu font.
With these changes it takes only(1) one minute now.

More coming.

de66a6466c [subset] Add --desubroutinize 
This seems to both make the font smaller for small subsets, and works
around a bug in our CFF hint stripping logic.

So, if you are passing --no-hinting, do pass --desubroutinize.

4447a76c33 [subset] If DSIG is to be retained, drop all signatures 
Now DSIG can be retained by passing --drop-tables-=DSIG.
The embedded signatures will be dropped but empty table
retained.

590c8777a6 [subset] Add --ignore-missing-glyphs and --no-ignore-missing-unicodes 
Move glyph checking into the subsetter.  Also fix --gids.  Previous
patch's implementation was wrong as it was picking up glyphs from
sorted glyph-name list, NOT the glyph order!
