Pull up following revision(s) (requested by riastradh in ticket #795):
sys/dev/dksubr.c: revision 1.112
sys/arch/xen/xen/xbd_xenbus.c: revision 1.95
sys/dev/scsipi/sd.c: revision 1.328
sys/dev/dkvar.h: revision 1.32
sys/dev/ld.c: revision 1.109
sys/dev/cgd.c: revision 1.120
sys/dev/raidframe/rf_netbsdkintf.c: revision 1.380
sys/dev/ata/wd.c: revision 1.458
Add a flag to dk_dump for virtual disk devices.
If a disk is backed by a physical medium other than itself, such as
cgd(4), then it passes DK_DUMP_RECURSIVE to disable the recursion
detection for dk_dump.
If, however, a device represents a physical medium on its own, such
as wd(4), then it passes 0 instead.
With this, I can now dump to dk on cgd on dk on wd.
