1740916ede [draw] Remove check for no-op 
This is unnecessary overhead. Up to rasterizers to handle this.  Plus,
this throws off point-numbers in uses that rely on it.

Disabled one test that broke with this.

067f90a820 [subset] Fix for fuzzer timeout. 
Fixes https://oss-fuzz.com/testcase-detail/5549945449480192

In prune_langsys: move LangSys visited check up before any work is done for a LangSys. In this particular case the compare() method is responsible for the majority of the time spent and wasn't being guarded with a visisted check.

69d8f27c69 [meson] Require 0.55.0 
We implicitly require it for building ragel subproject. This new version
requirement should satisfied in both Fedora 33 and Debian bullseye, and
not be too cutting edge for us.

f51b48c8e7 [subset] Fix fuzzer found memory leak. 
Happens because an insert into a map with an invalid key reports successful, but this causes the set being inserted to be lost.

c0f3af91b8 [subset] speed up add_gid_and_children and adjust op limit. 
Fix for fuzzer timeout: https://oss-fuzz.com/testcase-detail/5001604901240832.

- Operation limit is per glyph, so 100,000 should still be far more than needed.
- Switches from for(...) to while(...) loop for iteration. for(...) calls it.end() which in this case triggers a complete iteration.
- Cache CompositeGlyph size in the iterator to avoid needing to recalculate it.

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.
