Michael Davidsaver 0c61ac0833 stack traces with any exception class ...

Define THROW_EXCEPTION(E) which takes an exception class instance,
and uses it to construct an instance of a class which is a subclass
of E and ExceptionMixin.  The original instance is discarded, and
the newly constructed sub-class is thrown.  Equivalent to
"throw E;".

Define THROW_EXCEPTION2(ETYPE,MSG) which takes an exception class
type, and argument.  Directly constructs a ExceptionMixin sub-class
with the given message argument.  Equivalent to
"throw ETYPE(MSG);".

Define PRINT_EXCEPTION2(E, FP) If E is a instance of a sub-class of
ExceptionMixin then write information to FP (FILE*).

Define SHOW_EXCEPTION(E) If E is a instance of a sub-class of
ExceptionMixin then return a std::string with information.
