Behdad Esfahbod 0ded6a70c8 [subset] Fix another fuzzer issue 
Addition could overflow on 32bit arch.

Khaled Hosny c65e1e0842 [test] Run AOTS cmap tests with ot font functions only 
We are not interested in testing FreeType cmap support.

Fixes most format 4 tests. The remaining test seems to be peculiar, and
I can’t find any cmap implementation that produces the expected output.

Khaled Hosny 8396c523b6 [test] Add AOTS cmap tests 
Uses https://github.com/adobe-type-tools/aots/pull/3

Related to https://github.com/unicode-org/text-rendering-tests/issues/70

We don’t support format 4 or 8, so these tests are disabled. We support
format 4 but most of the tests are failing, investigating.

Khaled Hosny 50379fbb15 [util] Don’t split text at new lines in batch mode 
In batch mode (which is used for testing) we are probably not interested
in splitting text into lines as we could have split the string into
different tests. This fixes a bunch of AOTS tests that use newlines as
input.

Khaled Hosny 92b85749f2 [util] Strip quotes when parsing features 
When running in batch mode, the quotes are not stripped by the shell and
end up in the feature string. This breaks one of the AOTS tests.

Alternatively, we can remove the quotes from the test files, not sure
which is less hacky, though!

If size was > INT_MAX, then the out-of-room check was failing to perform
as intended.
