Behdad Esfahbod 1b7994cb3a [aat] Support feature ranges 
The hard way...

A bit uglier than I liked it to be, but is proper at least.

Behdad Esfahbod 24a4d397ba [aat] Allow disable feature ranges 
Fixes https://github.com/harfbuzz/harfbuzz/issues/4020

This is a hack.

To implement this properly we need to treat runs with different features
as independent runs for running the state machine, as the subtable flags
might be different. That would be a significant change to our internal
implementation.

Behdad Esfahbod 95df00aec1 Hide a few static methods 
Looks like static methods that do not get inlined end up exported.
We have a lot more.  Need to protect all at some point.  Wish there
was an easier way, like the visibility flag we pass that automatically
hides all inline methods.

Was exposed by check-symbols.sh when compiling on OS X 10.14 with:

$ make CPPFLAGS=-Oz CXXFLAGS=-flto=thin LDFLAGS=-lc++

Behdad Esfahbod 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.

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

Test with:

$ hb-shape Zapfino.dfont Zapfino
[Z_a_p_f_i_n_o=0+2333]

$ 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
[Z_a_p_f_i_n_o=0+2333]
