Name selectors should delegate to document.getElementsByName

[sil]

The selector $("*[@name=foo]") should delegate to document.getElementsByName("foo"), since getElementsByName is natively implemented and therefore faster. (This assumes that you can recognise this selector type fast enough that it's worth checking for it to do the delegation, of course.)

I did a quick benchmark, the page had 533 elements, 7 of them matched the name. The call was

$('[name=foo]');

Both patches break "selector module: attributes" test 19. and 20., related to :not()

Modification, skips not's

Somewhat shorter, skips not's

I made a few attempts but it just fails when doing :not. I restricted it to only positive filters, see if this passes, I g2g, I'll try to test this myself :)

Fixed in [5343].

document.getElementsByName can only retrieve elements in the document tree. see #2787

Right, reverted at [5460], good catch.
