e132741b2c [feaLib] Parse languagesystem in the same way as all other statements 
In the new version, the parse_languagesystem_() function returns
an ast.LanguageSystemStatement, which then gets appended to the
current list of statements by the caller. Before this change,
the parse_languagesystem_() function would always append the
newly parsed statement to the list of top-level statements.
In practice, it does not matter because `languagesystem` is
only valid at the top level, but there is no good reason why
the parser method would have to be different from all other
constructs.

6d7540ecac [feaLib] Move block parsing to a separate method 
We will soon support additional blocks beyond `feature`,
and keeping this refactoring separate from new functionality
makes it easier for code reviewers to follow the changes.

4bcdc60ca8 [feaLib] Remove write() methods 
For now, it looks like we won't need them for anything; removing this
code makes the codebase a little bit less complicated.

08d01bb24d [feaLib] Parse substitution rules for LookupTypes 1 and 3

ac700b0af5 Support FILENAME tokens when lexing OpenType feature files 
When the lexer encounters the "include" keyword, it now enters
a special mode for scanning file names.  After having scanned over
the file name, the lexer goes back to normal.  The exact format
of file name strings is not defined by the OpenType feature file
specification, so we accept any character that is not a closing
parenthesis.

612d2122ad Store file path in Lexer 
This simplifies the implementation of the parser for
OpenType feature files, since it can now just keep
token locations returned by the lexer.  Before this
change, the parser had to un-pack the location tuples
and build new tuples that included the file path.
