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.
