JS_GetStringCharsAndLength was removed, use
JS_Get{Latin1,TwoByte}StringCharsAndLength instead.
Actually handle strings in both the Latin1 and TwoByte cases since we
need to.
This saves some space when serializing and also when running as they are
stored that way in the vm.
Also handle the error case.
Patch by leper.
