Behdad Esfahbod a9a607d360 [variations] Support multiple axes with same tag, aka HOI
The axes in fvar are in arbitrary order, NOT sorted. Hence have to
lsearch all entries.

Khaled Hosny 71a6296620 [tests] Make record-test.sh work with .otf files
It hard-codes the file extension, but fonttools sunset will use .otf for
CFF fonts, so hard-code the output file from subset as well.

Garret Rieger bc06af977f [subset] speed up feature collection when tags are specified.
Precompute a feature index filter to avoid needing to iterate the feature tag list for each encountered feature index. For this particular fuzzer case speeds up feature collection from 50s to 2s.

Behdad Esfahbod bdfed8f113 [blob] Add failing versions of create API
Fixes https://github.com/harfbuzz/harfbuzz/issues/2567

New API:
+hb_blob_create_or_fail()
+hb_blob_create_from_file_or_fail()

Use these in util/ to distinguish empty file from not-found file.
Only err on the latter.
