2ee1d9f555 [blob] Change null object memory mode to DUPLICATE 
We never rely on that being equal to readonly.  Just not being
writable.  Maybe not even that given that the object is inert.

In prep for next commit, using default null pool.

8bb97d2ce1 Revert back hb_bytes_t.cmp() to the scheme it was 
But fix UBSan complaint.

There's nothing in hb_bytes_t that guarantees lexical ordering, and
ordering by length first is much faster.

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.
