000bf81700 Default to "\n" for newlinestr instead of None 
If newlinestr is None, os.linesep is used, bu it is the third millennium
and we don’t need or want different line endings per-platform.

Fix for #2293: allow more than one lookahead glyph/class in contextual positioning with "value at end" (#2294) 
* add test that fails for #2293

* fixing #2293: rewrite of contextual positioning logic, ensure len(suffix) > 1 yields the correct result; checking more edge cases and raising errors inspired by makeotf

* test error cases

* only check when we actually have a value

* catch one more case that makeotf errors on and we didn't

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.

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.
