url: trim leading and trailing C0 control chars

Emulate the WHATWHG URL parse behavior of trimming leading and trailing
C0 control characters. This moves url.parse() slightly closer to
WHATWHG URL behavior. The current behavior is possibly insecure for some
uses. (The url.parse() API is marked as Legacy and the documentation
specifically says it has known bugs and insecure behaviors. Still this
change makes a lot of sense.)
