AttributeAffectsStyle belongs next to HasStateDependentStyle on
nsIStyleRuleProcessor rather than on nsIStyleSheet.  While doing this, the
nsCSSStyleSheet implementation could be simplified and converted from
nsHashtable to pldhash.

This is work in progress.  It compiles, but I haven't tested it yet.

Attached file testcase
I used this testcase and a |printf| right after the change in
nsCSSFrameConstructor.cpp to verify that the changes are doing what I expected.
 (I got |affects==0| for the first and fourth buttons and |affects==1| for the
second and third.)

Everything seems to work just fine.

How about a clearEntry callback to fix the array leak, too? :-)

Odd indentation....

I know you just copied that refcounting, but could we make that an nsCOMPtr? 
And maybe even fix the place you copied from?

(we should really have a decent way to not have all this identical-looking
code... most of this file is screaming "Macro!" at me... but that's a battle
for another day).

Nice simplification of the attr hash stuff....
