I forgot to check in these changes for a long time. This adds

* kern/rescue.c (pupa_rescue_cmd_rmmod): Call pupa_dl_unload, if
possible.
* kern/dl.c (pupa_dl_ref): Refer dependending modules
recursively.

Don't call pupa_dl_unload implicitly, because PUPA can crash if
a module is unloaded before one depending on that module is
unloaded.
(pupa_dl_unload): Unload depending modules explicitly,
if possible.

the size of the conventional memory and that of so-called upper
memory (before the first memory hole).
Instead of adding each found region to free memory, use
add_mem_region and add them after removing overlaps.
Also, add only 1/4 of the upper memory to free memory. The rest
is used for loading OS images. Maybe this is ad hoc, but this
makes it much easier to relocate OS images when booting.
