Ted Kremenek 0208793e41 Add most of the boilerplate support for scanf format string checking. This includes 
handling the parsing of scanf format strings and hooking the checking into Sema.
Most of this checking logic piggybacks on what was already there for checking printf format
strings, but the checking logic has been refactored to support both.

What is left to be done is to support argument type checking in format strings and of course
fix the usual tail of bugs that will follow.
