Subject: cpp conversion: fix One-Definition-Rule violations

Defining struct pj_opaque with different definitions is a violation
of the C++ One-Definition-Rule. When using link-time optimizations, this
could break badly.
The solution adopted here is to wrap those structures into a C++
anonymous namespace so they are considered different
