792a958d6c [feaLib] Implement parser for multiple substitutions (GSUB LookupType 2) 
Actually building the GSUB table is not implemented yet, since this
will probably need changes to otTables.

86004df3b0 [feaLib] Reject script dflt and language DFLT 
These are invalid casing variants of the frequently used
`script DFLT` and `language dflt`. Adobe's makeotf tool
does a similar check.

20392fb491 [feaLib] Fix test failures caused by an earlier bug fix 
An earlier change made sure that language tags would always be
four characters in length, even when ending in whitespace.
This made a few test cases in parser_test.py fail. By accident,
I had only run builder_test (instead of all unittest in fonttools)
before committing that change.

6140a4ec2b [feaLib] Build ScriptList subtable 
Also, fixed a bug that caused language tags to be sometimes stripped.
Added an assertion to verify that language tags are always 4 chars.

102c0e0e56 [feaLib] Handle languagesystem, script and languaguage statements

"languagesystem DFLT dflt;" must be the first languagesystem

b54c04f1d4 [feaLib] Enforce language "dflt" for script "DFLT" 
Also add ';' to some langaugesystem test cases. This makes the
snippets syntactically valid. The parser is still expected to
reject them for other reasons, just as before this change.

9ddd313577 [feaLib] Merged LexerError and ParserError 
This simplifies the public API to the library.  For clients, it does
not matter which exact component was detecting an error.  And we will
soon have more components; there would be little point in declaring
CompilerError, TableBuilderError, and so forth.

f38cc9f821 Write XML for alternate glyphs (GSUB lookup type 3) in deterministic order 
Before this change, the XML output for GSUB lookups of type 3
was not deterministic; multiple runs of TTX on the same font
could therefore emit the alternates in a different order.

Since alternate glyphs are sets, this change makes no semantic
difference to the output. However, a deterministic ordering
is needed for tests that compare GSUB tables in TTX format.

07458f62dd Support non-BMP characters for synthetic glyph names 
When a font supplies no glyph names in its 'post' table, fontTools
builds synthetic glyph names by reversing the 'cmap' table.
After this change, the library looks at all 'cmap' subtables for
Unicode, irrespective of format or platform. For example, glyph #4
in NotoSansOldItalic-Regular.ttf gets now named "u10300" instead of
"glyph00004".

Moved the code for building a reversed 'cmap' table into the cmap class,
for easier testing.

80966aa7e3 Revert "[travis] compile Brotli using build_ext --libraries=stdc++ on pypy3" 
This reverts commit 76dbfef6d4bb11eb4c796f26ebebe1045b6dbbf8.

We don't support pypy3 anymore, until it's updated to 3.3, which shouldn't need
this fix.

89f0c0ce7f Speed up hdmx loading by using custom glyphnamed-list 
The data-structure can be used in more places, but it's most beneficial in
this table since hdmx tables can have tens of ppem's, each having a dictionary
keyed by glyphnames...
