Garret Rieger 918193ebf9 [subset] fix a class of fuzzer timeouts caused by large shared coverage tables. 
More acurately estimates the op count for CoverageFormat2 tables as the population size instead of the size in bytes.

Garret Rieger ddd0f7f40b [subset] Add a test for CFF2 instancing. 
Adds option to disable the fonttools comparison check in the test. This is needed since CFF2 instancing is not yet supported in fonttools.

Qunxin Liu af1e605be2 [instancer] bug fix 
It's possible that length of all_points equals to 4 for non-empty
glyphs: a composite glyph which contains only one child glyph that is
empty.

Behdad Esfahbod 64fa5cd482 [GPOS] Fix assert fail introduced recently 
Was introduced in 8708b9e081.

If these lookups are recursed to from (Chain)Context out-of-order,
it was possible that last_base > buffer->idx, in which case we
were attaching marks to a base after them... and an assertion
was failing fortunately.

Andres Salomon 0bbc9d5256 [fonts] move OFL-1.1 license to a higher directory 
There's a bunch of font directories inside of test/ for which the vast
majority of fonts are licensed under the SIL open font license. We currently
have a COPYING file in test/shape/data/in-house/COPYING that says that most
of the fonts are OFL-1.1, but that doesn't apply to the fonts in, say,
test/api/fonts/ or test/fuzzing/fonts/. Since there are so many OFL-1.1
fonts all over test, let's move the COPYING file to the top-level test/
directory.

Andres Salomon c622c6b883 [font] update the license url for TestGVAREight.ttf 
The url in the exif data incorrectly links to a proprietary license. However,
permission was granted for distribution under Apache-2 as part of another project,
so link to that project's license instead.

fixes #4062

Qunxin Liu 27f72f0deb [instancer] avoid double free for compiled glyph bytes 
also increase the HB_GLYF_MAX_POINTS limit to 20000 cause the test file has a
