This change is some refactoring of Mark Johnston's changes in r329375
to fix the memory leak that I introduced in r328426. Instead of
trying to clear up the possible memory leak in all the clients, I
ensure that it gets cleaned up in the source (e.g., ffs_sbget ensures
that memory is always freed if it returns an error).
The original change in r328426 was a bit sparse in its description.
So I am expanding on its description here (thanks cem@ and rgrimes@
for your encouragement for my longer commit messages).
In preparation for adding check hashing to superblocks, r328426 is
a refactoring of the code to get the reading/writing of the superblock
into one place. Unlike the cylinder group reading/writing which
ends up in two places (ffs_getcg/ffs_geom_strategy in the kernel
and cgget/cgput in libufs), I have the core superblock functions
just in the kernel (ffs_sbfetch/ffs_sbput in ffs_subr.c which is
already imported into utilities like fsck_ffs as well as libufs to
implement sbget/sbput). The ffs_sbfetch and ffs_sbput functions
take a function pointer to do the actual I/O for which there are
four variants:
ffs_use_bread / ffs_use_bwrite for the in-kernel filesystem
g_use_g_read_data / g_use_g_write_data for kernel geom clients
ufs_use_sa_read for the standalone code (stand/libsa/ufs.c
but not stand/libsa/ufsread.c which is size constrained)
use_pread / use_pwrite for libufs
Uses of these interfaces are in the UFS filesystem, geoms journal &
label, libsa changes, and libufs. They also permeate out into the
filesystem utilities fsck_ffs, newfs, growfs, clri, dump, quotacheck,
fsirand, fstyp, and quot. Some of these utilities should probably be
converted to directly use libufs (like dumpfs was for example), but
there does not seem to be much win in doing so.

psm(4): Always initialize used values in debug print

Fully populating it with values in get_mouse_status() can fail due to

Additionally, nothing in API constrains 'len' to be >= 3. In practice,
every caller passes three, so perhaps that argument should just be removed.

dhclient violates RFC2131 when sending early DHCPREQUEST message to re-obtain old IP
When dhclient first starts, if an old IP address exists in the
dhclient.leases file, dhclient(8) sends early DHCPREQUEST message(s)

contain the old IP as a requested-IP-address option in the message
body (correct) but also use the old IP address as the packet's source
IP (incorrect).
RFC2131 sec 4.1 states:
DHCP messages broadcast by a client prior to that client obtaining
its IP address must have the source address field in the IP header

Allow physically non-contiguous chain frames allocation in mps(4)/mpr(4).
Chain frames required to satisfy all 2K of declared I/Os of 128KB each take

allocate as physically contiguous. This patch removes that physical
contiguousness requirement, leaving only virtual contiguousness. I was
thinking about other ways of allocation, but the less granular allocation
becomes, the bigger is the overhead and/or complexity, reaching about 100%
overhead if allocate each frame separately.
The patch also bumps the chain frames hard limit from 2K to 16K. It is more
than enough for the case of default REQ_FRAMES and MAXPHYS (the drivers will
allocate less than that automatically), while in case of increased MAXPHYS
it will control maximal memory usage.
