Reviewed by Anders.

• changed deleteAllValues so it can work on "const" collections Deleting the values affects the values, not the pointers in the collection, so it's legitimate to do it to a const collection, and a case of that actually came up in the XPath code.

• wtf/HashMap.h: (WTF::deleteAllPairSeconds): Use const iterators. (WTF::deleteAllValues): Take const HashMap reference as a parameter.
• wtf/HashSet.h: (WTF::deleteAllValues): Take const HashSet reference as a parameter, and use const iterators.
• wtf/Vector.h: (WTF::deleteAllValues): Take const Vector reference as a parameter.

• added more functions that are present in <math.h> on some platforms, but not on others; moved here from various files in WebCore

• wtf/MathExtras.h: (isinf): Added. (isnan): Added. (lround): Added. (lroundf): Tweaked. (round): Added. (roundf): Tweaked. (signbit): Added.
