This patch implements the algorithm HTML5 describes for getting reflected unsigned attributes. From section 2.8.1:

"If a reflecting IDL attribute is an unsigned integer type (unsigned long) then, on getting, the content attribute must be parsed according to the rules for parsing non-negative integers, and if that is successful, and the value is in the range 0 to 2147483647 inclusive, the resulting value must be returned. If, on the other hand, it fails or returns an out of range value, or if the attribute is absent, the default value must be returned instead, or 0 if there is no default value."

Before anyone reviews this, it might be nice to let all the EWS bots do their thing before changing the review flag since I've only tested the code generation on the Mac.

The patch looks great; we also need a test that shows the actual behavior change in running JavaScript. Something in the LayoutTests directory. I’m going to say review- because that’s missing.

Thanks Darin. The new patch adds test cases for marquee's hspace and vspace properties, which are both reflected and unsigned.
