[PATCH 1/3] Use unique_xmalloc_ptr in interp

[Tom Tromey <tromey@adacore.com>]

This changes interp::m_name to be a unique_xmalloc_ptr, removing some
manual memory management.  It also cleans up the initialization of the
'inited' member, and moves the 'private:' and 'public:' keywords to
their proper spots.
