Previously alpha.security.ArrayBoundV2 produced very spartan bug
reports; this commit ensures that the relevant (and known) details are
reported to the user.
The logic for detecting bugs is not changed, after this commit the
checker will report the same set of issues, but with better messages.
To test the details of the message generation this commit adds a new
test file 'out-of-bounds-diagnostics.c'. Three of the testcases are
added with FIXME notes because they reveal shortcomings of the existing
modeling and bounds checking code. I will try to fix them in separate
follow-up commits.
The `stdin` declaration should be within `extern "C" {...}`, in C++
mode. In addition, it should be also marked `extern` in both C and
C++ modes.
I tightened the check to ensure we only accept `stdin` if both of these
match. However, from the Juliet test suite's perspective, this commit
should not matter.

This patch introduces the namespaces for the configured functions and
also enables the use of the member functions.
I added an optional Scope field for every configured function. Functions
without Scope match for every function regardless of the namespace.
Functions with Scope will match if the full name of the function starts
with the Scope.
Multiple functions can exist with the same name.
