libsyntax: accept only whitespace with the PATTERN_WHITE_SPACE property

Browse source 
This aligns with unicode recommendations and should be stable for all future
unicode releases. See http://unicode.org/reports/tr31/#R3.

This renames `libsyntax::lexer::is_whitespace` to `is_pattern_whitespace`
so potentially breaks users of libsyntax.
