Steve Mokris 506a952ad2 Parse `extern "C"`, and use it to avoid FP reference warnings (#2234)
Previously, cppcheck discarded the `extern "C"` specifier.  This patch modifies cppcheck to parse each as a Scope in the symbol database, then uses that scope to avoid false positives when making recommendations about changing a function argument to be a reference (since variable references is a C++ feature, unavailable in C, and thus unavailable in `extern "C"`).

IOBYTE c32a568c1f fix #8965 ("(debug) Executable scope 'x' with unknown function." with rvalue parameter in method) (#2237)
I fixed the AST enough to pass testrunner but I don't believe it is
correct.

This code:

void Foo4(int&&b);

has this AST:

( 'void'
|-Foo4
`-&& 'bool'
  |-int
  `-b 'signed int'

but I don't believe && should have `bool`.
