[analyzer] Modernize CStringChecker to use CallDescriptions.

Authored by NoQ on May 28 2019, 4:47 PM.



This uses the new CDF_MaybeBuiltin flag to handle C library functions. It's mostly a refactoring pass, but it does fix a bug in handling memset() when it expands to __builtin___memset_chk() because the latter has one more argument and memset() handling code was trying to match the exact number of arguments.
