Fixing compile time errors irt (, e => as e, print(), ocat now 0o not 0) exception handling for Python 3 (#3851)

Browse source 
* Fixing compile time errors irt a) exception handling for Python 3 in util, also: b) problem octal usage (fixed) and c) print json_dump -> print(json_dump(xyz) ... et al

* This code was not Python 2.4 compliant. Octal codes and exception handling is now working with Py 2.4, 2.6, & 3.5.

* Fixing formating (or rather reverting an non 2.4 compatible change). Works in compile & runtime checking.

* a) revert to use print sys.stderr not fail_json; b) fixed var name in exception

* Python 3 compatible print (print >>sys.stderr will generate a TypeError - now uses sys.stderr.write instead).
