Fixes:
[cast] redundant cast
[rawtypes] found raw type
[serial] serializable class has no definition of serialVersionUID
Also suppress warning: auxiliary class TargetLanguageBase in ./inherit_target_language.java should not be accessed from outside its own source file
The strings from the Octave array are returned in a temporary
std::string object so we need to make a copy of them or else the
final string ends up replicated as all elements.
Unfortunately argcargvtest.i was only checking the final element's
value, so fix it to test both the elements as a regression test for
this, and to catch any similar issues with other target languages.
