add optional arg [aspacemgr] to v.info memory to show aspacemgr segments.

When investigating Valgrind out of memory situation,
it is useful to be able to output the list of segments of the
aspacemgr at any moment.
The GDB monitor command "v.info memory" has now an optional
argument allowing to output this list of segments
