0c66043a92 [coretext] Fix memory leaks. 
In `reference_table`, if the data is empty and we return early,
we still need to release the data object.

In `hb_coretext_shape`, there two edge cases where an early
return should release the attributed string.

e89df6e1ae [aat] Limit number of DontAdvance transitions 
Remove the faulty loop-detection logic. Use max-ops for breaking
out of infinite loops or heavy work.

85be365ed9 Use KernSubTableFormat2::rightClassTable 
Issue originally reported at http://cppfiles.com/chromium.txt .

This fixes what appears to be a copy - paste issue which causes both
KernSubTableFormat2::rightClassTable and the 'right' argument to
KernSubTableFormat2::get_kerning to go unused.

c8f2a4f5b9 hb-common.cc: Hatran script is right-to-left (#714) 
"Hatran is written from right to left horizontally"

http://www.unicode.org/L2/L2012/12312-n4324-hatran.pdf

This ancient script was added with Unicode 8.0.

Also this spreadsheet (referenced in an inline comment in the
source code) has it as RTL: http://goo.gl/x9ilM

949f6af289 Disallow sanitize recursing into Extension subtables multiple times 
Fixes https://oss-fuzz.com/v2/testcase-detail/5216838347653120
which is a stack overflow, not by way of infinite recursion, just
being deep.  That's disallowed anyway, so catch it as it happens,
not afterwards.
