    gccrs: libproc_macro: Add namespace to Ident
    
    Add a new Ident namespace to group Ident related enumeration and
    structures.
    
    libgrust/ChangeLog:
    
            * libproc_macro/ident.cc (Ident::make_ident): Add Ident
            namespace.
            * libproc_macro/ident.h (Ident__clone): Likewise.
