0f8f71d5ec [feaLib.lexer] modify make_lexer_ factory to take a 'file_or_path' argument 
if 'file_or_path' is a file object keep it open, otherwise read the data from
the path and then close it.

7eed24725f Allow include statements not terminated by a semicolon 
The lexer passes the semicolon to the parser, which will read over it.

6e291cf705 [feaLib] Fix parsing float numbers 
Numbers with integral parts >= 10 were incorrectly parsed as integers as
next_char always pointed to the second number not the decimal point.

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.

5270a978a9 [feaLib] Support hexadecimal numbers 
The OpenType Feature File specification does not specify hex numbers
as explicit token type, but they appear several times in the examples
given by the spec.

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.
