I forgot to check in these changes for a long time. This adds
incomplete support for VGA console, and this is still very
buggy. Also, a lot of consideration is required for I18N,

possible.
* kern/dl.c (pupa_dl_ref): Refer dependending modules
recursively.
(pupa_dl_unref): Unrefer depending 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.

(pupa_machine_init): Set PUPA_LOWER_MEM and PUPA_UPPER_MEM to
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.

correctly.

Don't follow symbolic links.
Fix the path-constructing code.
* util/i386/pc/biosdisk.c [__linux__] (BLKFLSBUF): New macro.
(pupa_util_biosdisk_open) [__linux__]: Get the size of a device
by a BLKGETSIZE ioctl first, because block devices don't fill
the member st_mode of the structure stat on Linux.
[__linux__] (linux_find_partition): Use a temporary buffer
REAL_DEV for the working space. Copy it to DEV before returning.
(open_device) [__linux__]: Call ioctl with BLKFLSBUF to make the
buffer cache consistent.
