Summary: Add some string utility functions, notably to format strings, get lengths, convert a string to a number. Those functions will be used in reports and flags (coming up next). They were mostly borrowed from sanitizer_common. Make use of the string length function in a couple places in the platform code that was checked in with inlined version of it. Add some tests.
