Garret Rieger 3d534b146c [subset] convert subset input flags into bit flags. 
Store the flags in a bit set. Updates the public api to work with the bit set directly.

Khaled Hosny f6c67a5fcf [test] Open file in UTF-8 
It is 2021 and Python still does not default to UTF-8 on Windows!

Ben Wagner a78eb43c79 Construct user_data in hb_object 
hb_object's user_data is created lazily. The previous implementation of
hb_object_set_user_data created space for the user_data but did not
actually construct it. This means that hb_user_data_array_t's lock was
not constructed. If hb_mutex_t is backed by an implementation which
requires that it be constructed (not just zero initialized) then errors
will occur when taking the lock when setting the user data.

Change hb_object_set_user_data to construct the user_data in the created
space and hb_object_fini to call the destructor.

Khaled Hosny 278f44dcee [test] Speed-up subset tests by saving TTX dump 
Speed-up subset tests by saving TTX dump of expected output instead of
generating it each time the tests are run.

Cuts down meson test --suite=subset on my system from:
real	0m38.977s
user	1m12.024s
sys	0m10.547s

to:
real	0m22.291s
user	0m44.548s
sys	0m9.221s

Khaled Hosny 895162d6f3 [test] Account for mark zeroing in AOTS tests 
The AOTS are not written with the face that mark glyphs gets their

Behdad Esfahbod 2d54c34680 [subset/VarStore] Fix OOM in fuzzer test 
The test in question is the one added in c68a00b92e.
Culprit is that it's allocating lots of memory because of region_indices that
are out-of-range anyway. So, try to filter those out first.

Khaled Hosny ddf87ffb22 [test] Add generated tests for emoji clusters 
Fixes https://github.com/harfbuzz/harfbuzz/issues/3017

Uses AdobeBlank2.ttf from:

  https://github.com/adobe-fonts/adobe-blank-2

instead of a dummy empty font so that everything maps to GID 1 and
control code points are kept instead of being dropped because there is
not space glyph (otherwise we’d need to identify control code points
somehow when generating the expectations).

Garret Rieger acbd8b27dc [subset] temporarily disable COLRv1 subsetting. 
Currently COLRv1 spec is being changed so the subsetting implementation is out of sync. Disable subsetting by failing sanitization for COLRv1 tables and disable all colrv1 tests.

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!
