[ot] Keep substituted Default_Ignorables ( #2886 )
...
Don’t replace Default_Ignorables with zero-width space if they are
substituted or multiplied, not just when ligated.
After this change, HarfBuzz output matches that of Uniscribe and
CoreText for the new tests.

Fix djgpp complains by tweaking templates ( #1579 )
...
For some reasons djgpp doesn't understand "unsigned int" can be same
with one of uint*_t anyway so lets do that for it explicitly.
Just to note, our CI's djgpp is based GCC 7.2.0 and isn't old.

[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.
