Hey Jakub.

Here's a way to start in on this.

This does two things:

1) adds default visibility attributes to 
namespace std
namespace std::tr1
namespace __gnu_cxx

2) adds hidden visibility attributes to
namespace __gnu_internal

There are a couple of things I want to do in addition to this, but these can be
added in later. (Such as move as much __gnu_internal into anonymous namespaces,
consolidate various internal namespaces into anonymous namespaces or
__gnu_internal, relocation tuning, consolidation of visibility schemes between
libsupc++ and libstdc++). 

Testing on so_7 with namespace associations is in progress.

tested x86/linux
tested x86/linux CXXFLAGS="-fvisibility=hidden" (fails)
