CSS 2.1 @charset tests invalidated by Level 3

CSS Syntax Level 3 invalidates some @charset tests in the CSS 2.1 test
suite. It’s not good for anyone when people think that a Level 3
implementation is buggy when it correctly implements Level 3 but the
Level 2.1 test suite shows red. Therefore, please rescind the
following tests per
http://w3cmemes.tumblr.com/post/31865121758/the-joker-shares-his-approach-on-css2-1-issues

Tests that are invalid per Level 3 but still pass (i.e. green for a
different reason than the reason why they are supposed to be green):

http://test.csswg.org/suites/css2.1/20110323/html4/character-encoding-028.htm

The reasons why the above are now invalid:
 1) BOM now overrides HTTP
 2) BOM now overrides @charset
 3) Non-ASCII @charset no longer gets honored
 4) Bogus charset names now cause @charset to be ignored, not the
sheet to be discarded.

Tests whose validity was questionable to begin with:
