64122b5a44 [subset] don't visit lookup if covered glyph set has failed. 
If covered glyph set is in error then the same lookup can be recursed into repeatedly potentially causing a fuzzer timeout. Fixes: https://oss-fuzz.com/testcase-detail/5416421032067072.

c35d786397 [subset] never drop the 'pref' feature. 
Never ever drop feature 'pref', even if it's empty. Harfbuzz uses it to choose the shaper for Khmer.

56ca435787 [subset] fix for collect_features and remove_redundant_lamngsys 
previously remove_redundant_sys () is missing in harfbuzz, after
redundant langsys removal, some features are removed as well in
prune_features() in fonttools. This change is trying to get the same
result between harfbuzz and fonttools.

190b7a98f8 [subset] Update PairPosFormat2 subsetting to match fontTools updated subsetting (https://github.com/fonttools/fonttools/pull/2221) 
- subset class def 1 against the coverage table.
- Don't re-use class 0 in class def 2.
- Ignore class 0 glyphs for the purposes of determing format 1 vs format 2 encoding for ClassDef.

Add an additional test case which demonstrates these issues.

[ot] Keep substituted Default_Ignorables (#2886) 
Don’t replace Default_Ignorables with zero-width space if they are
substituted or multiplied, not just when ligated.

After this change, HarfBuzz output matches that of Uniscribe and
CoreText for the new tests.

was not merging clusters if something from before base and after base

554aaa0c5d [build] Fix make distcheck 
A regression from 7b77ce0507.
It was caught by the CI build in the PR, but apparently we are now used
to CI failures that they are effectively ignored.

Also, yay for multiple build systems.

Currently the fuzzer can create arbitarily long inputs which once big enough will trigger a timeout.
