move octave_config_features function out of header file

* oct-conf-features.h: New file.
* module.mk: Generate octave-conf-features.cc instead of
oct-conf-features.h.
* toplev.cc (Foctave_config_info): Call octave::config::features.
* config-features.sh: Adapt to use of namespace.  Make internal data
static and initialized only once.
