Namespace management for static multi-database support

Now in libodb the odb::core namespace is split into odb::common (database-
independent stuff) and odb::core proper, which imports odb::common. Each
database runtime now defines odb::<db>::core namespace which also imports
odb::common and adds the database-specific bits. The overall idea is that
one can do using namespace odb::<db>::core just like for odb::core.
