Behdad Esfahbod 89b1906d99 [aat] More adjustment to ContextualSubtable 
See comment.

With this, MORX-20 passes if I turn --verify off.  Our unsafe-to-break
logic is currently broken in presence of end-of-text actions.  That's,
ugh, extra work to fix.  Let me try...

Bruce Mitchener e8859fca3e Enable use of atexit() on macOS and related platforms. 
The atexit() man page indicates that this is expected to behave
in the expected way on unloading of shared libraries.

Bruce Mitchener 148ca61075 [ot-layout] Fix nullptr dereference. 
If the `calloc` for `gsub_accels` or `gpos_accels` fails, then the
unlikely branch afterwards can be taken, which frees up the
`hb_ot_layout_t`, but since those fields can now be `nullptr`, then
we don't want to dereference them.

Bruce Mitchener 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.

bungeman 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.

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.
