I'm wondering if we want "namespaces" to mean "linker namespaces".  I
can imagine someone adding a command to iterate over the
DW_TAG_namespace entries in the available DWARF info and then print
things regarding those entries.  That too could be a good (possibly
better) candidate for a GDB "info namespaces" command.

What I'm suggesting here is that we might want to add a qualifier to
the command and related names, i.e. that the new command be named
"info linker-namespaces" instead of just "info namespaces".  Likewise,
add qualifiers for _active_namespaces and _current_namespaces.
