Detailed Description

Instances of known_function are registered with the known_function_manager
when the analyzer starts.

The known_function_manager has responsibility for determining which
known_function instance (if any) is relevant at a call site, by checking
name or id, and by calling known_function::matches_call_types_p to ensure
that the known_function's preconditions hold (typically assumptions about
types e.g. that "has 3 args, and that arg 0 is of pointer type").

The known_function subclasses themselves have responsibility for
determining the outcome(s) of the call.
