Rewritten Exception class. Throw exception object, not its pointer and
catch by reference, so that remove problematic delete operator for
catched exception.

* test/*: All files throwing/catching exception.
Renamed argument from 'errno' to 'err', since errno is confused
with
errno defined in errno.h.
