* LayoutTests/TestExpectations:
* LayoutTests/imported/w3c/web-platform-tests/css/mediaqueries/negation-001.html:

Fix the test. The query

not ((unknown) or (monochrome))

evaluates using 3-valued Kleene logic to

-> not (unknown or false)
-> not unknown
-> unknown

which in media query context doesn't match. Firefox agrees.

* LayoutTests/imported/w3c/web-platform-tests/css/mediaqueries/test_media_queries-expected.txt:
* LayoutTests/imported/w3c/web-platform-tests/css/mediaqueries/test_media_queries.html:

Add more tests for 3-valued logic. Firefox passes all these too.

Also add a parsing test for an unknown function with extra whitespace.
