[cu2qu/ufo] return set of modified glyph names from fonts_to_quadratic 
In ufo2ft preProcessor, we need to know which specific glyphs were actually modified (converted to quadratic), in order to do other things while processing filters, not simply if the fonts were modified as a whole; thus, here I changed fonts_to_quadratic to return the set of modified glyph names instead of just True/False. The change is backward compatible because code that checks whether the returned value is True/False will continue to work since bool(set) is True for non-empty set, False for empty ones.

don't sort product of liga components to keep declaration order 
technically we are tweaking the original example from the spec but it keeps the spirit, so that the product of glyph classes produces the same representation in the font as if the sequences were manually enumerated (while keeping the declaration order)

2616ab959c feaLib: Drop glyph and class names length limit 
These were implemented to follow FEA spec, but makeotf does not seem to
have a name length limit any more (or it has a very large one, I tested
a 600-character name and it was accepted).

[featureVars] Re-use FeatureVariationRecord's when possible 
If a FeatureVariationRecord with the same ConditionTable exists re-use
it and append FeatureTableSubstitutionRecord’s.

Without this, in the following feature code only the first lookup will
be applied since there will be two FeatureVariationRecord with the same
ConditionTable, so the first will be matched and the other will be
skipped:

    conditionset test {
        wght 600 1000;
        wdth 150 200;
    } test;

    variation ccmp test {
        sub e by a;
    } ccmp;

    variation rlig test {
        sub b by c;
    } rlig;

With this change only one FeatureVariationRecord will be created with
two FeatureTableSubstitutionRecord’s.

2c07619344 [otlLib] make ClassDefBuilder class order match varLib.mergers 
see https://github.com/fonttools/fonttools/blob/c3d876/Lib/fontTools/misc/classifyTools.py#L77

i.e. we want (large classes first, then lexicographic order on the glyphs); previously otlLib was sorting by the _reverse_ of (small classes first, then glyphs lexicographic order) -- effectively comparing the reverse of the glyph sets of classes of the same size.

Fixes https://github.com/fonttools/fonttools/issues/3321

note the ttx dump of previously built fonts may change but there won't be any functional changes.
