7db9ba6ef6 [feaLib] Allow anonymous glyphclass in LookupFlags 
Almost everywhere else when a glyph class name is accepted, anonymous
glyph classes are also accepted. This is rather inconsistent and
inconvenient.

Move feature builders to otlLib 
Refactors feaLib, moving code which builds OpenType lookups into otlLib. Note that this changes feaLib's concept of `location` from a tuple to an object.

[feaLib] Introduce includeDir on Parser and IncludingLexer (#1973) 
This makes the directory to search for included files explicit.

Also use Python 3's FileNotFoundError to catch non-existant files instead of a workaround for Python 2.

[feaLib] Support multiple lookups per glyph position (#1905) 
This allows for more than one "lookup ..." chaining statements at each glyph position in a chaining contextual substitution or positioning rule: e.g.

    sub a b c' lookup lookup1 lookup lookup2 d;

The corresponding change in the Adobe OpenType Feature File Specification (and implementation in makeotf) happened in adobe-type-tools/afdko#1132.

d24fd71934 [feaLib] Fix building chained alt substitutions 
Support was added in db49f20d6b2629e1ba25c4afd3fb60817387f3d6, but there
was only a parser test and no builder test, fix the build and add a
builder test based on the existing parser one.

4526e164f1 [feaLib] Check lookup index in chaining lookups 
Raise if lookup_index is None, which would happen only of the lookup

259e586f5d [feaLib] Ignore superfluous script statements 
Setting script that is the same as current language system should make
no effect. This is not documented in the spec, but it is what makeotf
does. This as the effect of preserving lookupflag when set before such a
script statement.

[feaLib] Check that glyph names referenced in the feature file are part of the glyph set (#1828) 
This checks that glyph names that appear in a feature file are actually
in the glyph set provided in glyphNames. If the set is empty, no check
is done. This preempts a KeyError later during saving of a TTFont object
and makes this case much more easily catchable.

Closes #1723.

ef2742593c Compare realpath against realpath 
On Windows, tests may be run in the user's temp directory, so the previous code
may compare C:\Users\nikolaus.waxweiler\ against C:\Users\NIKOLA~1.WAX\.

22bfc305ee [feaLib] fix mixed single/multiple substitutions 
If the single substitution involved a glyph class, we were incorrectly
using only the first glyph in the class.

Broken since ec6ff821f0e72022d7aec8794b6bb589d8f81808, apparently no one
else uses this feature!
