1082338525 [shape-plan] Only use shape-plan key to initialize hb_ot_shape_plan_t 
Such that we don't accidentally use info not in the cache key.

f521a28b4a Embed hb_ot_shape_plan_t into hb_shape_plan_t 
No other shaper will need shape_plan_data, by definition.  So, remove
abstraction layer and always create hb_ot_shape_plan_t as part of
hb_shape_plan_t.

385f78b312 [aat] Remove deleted-glyhs after applying kerx/kern 
Finally:  Fixes https://github.com/harfbuzz/harfbuzz/issues/1356

Test case:
$ ./hb-shape GeezaPro.ttc -u U+0628,U+064A,U+064E,U+0651,U+0629
[u0629.final.tehMarbuta=4+713|u064e_u0651.shaddaFatha=1@0,-200+0|u064a.medial.yeh=1+656|u0628.initial.beh=0+656]

The mark positioning (kern table CrossStream kerning) only works if deleted
glyph (as result of ligation) is still in stream and pushed through the
state machine.

There's a few more but those are functions that need to be filled in.

ffe3478448 [aat] Allow enabling/disabling features 
Only works at entire-buffer range, not sub-ranges.

Test with:

$ hb-shape Zapfino.dfont Zapfino --features=-dlig
[Z=0+416|a=1@-21,0+264|p_f=2+433|i=4+181|n=5+261|o=6+250]

$ hb-shape Zapfino.dfont Zapfino --features=+dlig

So '--features=-trak' or 'font-feature-settings: 'trak' 0;' can prevent
applying of tracking if used.

is now.

a62f37d6fa Change vendor features from Harf/Buzz to HARF/BUZZ 
a01194aaf4 (commitcomment-30772041)

"The tag space of tags consisting of four uppercase letters (A-Z) with no punctuation,
spaces, or numbers, is reserved as a vendor space. Font vendors may use such tags to
identify private features."

a01194aaf4 Enable two OpenType features, 'Harf' and 'Buzz' 
One early, before script-specific features, one late, after.  Allows font
developers to detect us and behave differently if needed.
