85630996b8 Fix buffer-overrun with Bengali reph positioning code 
This has no security implications whatsoever since we always keep
and extra element at the end of buffer, just in case.

a657f23ca3 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.

44f7d6ecde Guard against underflow when adjusting length (#421) 
* 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.

ffde3c9f9e 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.

+hb_ot_var_normalize_variations() and
+hb_ot_var_normalize_coords() instead.
