Blacklist another instance of Padauk ( #419 )
...
In https://crbug.com/681813 another instance of Padauk was identified
triggering collapsed glyphs. Blacklist this version by patching
hb-ot-layout.cc to print out gdef, gsub, and gpos table length, then
adding those to the list of blacklisted versions.

* Guard against underflow when adjusting length
With the fuzz-testcase in mozilla bug 1295299, we end up with a recursed lookup that removes 3 items, when `match_positions[idx]` is 0, which results in (unsigned) `end` wrapping to a huge value.
Making `end` a signed int is probably the simplest route to a fix.
Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1295299 .
* Add testcase for #421 .

hb-font: Fix a potentially undefined use of memcmp() ( #413 )
...
While it’s fine to call memcmp(x, 0, 0) in practice, the C99 standard
explicitly says that this is not allowed: even if the length is zero,
the pointer arguments must be valid.
