Fix an obvious bug from r186196 shadowing a variable, not correctly
appending the new mbuf to the chain reference but possibly causing an mbuf
nextpkt loop leading to a memory used after handoff (or having been freed)
and leaking an mbuf here.

Pass the fibnum where we need filtering of the message on the
rtsock allowing routing daemons to filter routing updates on an
rtsock per FIB.
Adjust raw_input() and split it into wrapper and a new function
taking an optional callback argument even though we only have one
consumer [1] to keep the hackish flags local to rtsock.c.

Unbreak no-ip and no-inet6 module builds with ipfw. For now continue to
build the ip_fw_pfil.c hooks and ipfw even in case of no-ip under the
assumption that the private L2 hook (which hopefully eventually will be a
pfil hook as well) can still be useful.

simultaneously with modifying other bits is undefined and may cause hangs.
The race should be handled in some other way, but for now just get back.

When script(1) reads EOF from input it starts spinning on zero-byte
reads eating 100% CPU. Fix this by skipping select on STDIN after
reading EOF -- permanently if STDIN is not terminal and for one second
if it is.
Also after reading EOF from STDIN we have to pass it to the program
being scripted. The previous approach was to write zero bytes into the
pseudo-terminal. This does not work because zero-byte write does not
have any effect on read. Fix this by sending VEOF instead.

This update eliminates a lock-order reversal warning discovered
whle tracking down the system hang reported in kern/160662 and
corrected in revision 225806 (MFC'ed as 225850). The LOR is not
the cause of the system hang and indeed cannot cause an actual
deadlock. However, it can be easily eliminated by defering the
acquisition of a buflock until after all the vnode locks have
been acquired.
As journaled soft updates first appeared in 9.0, this will be the
only MFC of this change.

- MFC r225778:
- Add missing interdependencies to kerberos libraries. Some of the
kerberos libraries were not linked properly (missing dependencies),
which causes 3rd party applications linking to fail when --as-needed
ld flag is used. I also added the --no-undefined ld(1) flag to make
sure that there're no missing dependencies.
When a status pointer is passed in mfi_dcmd_command does not return an
errno (if the ioctl is successful), so move the test for NO_HW_PRESENT
outside of the error case. This should fix incorrect reporting for
systems with a dead or no battery.
Additionally, handle error codes other than NO_HW_PRESENT by omitting
the battery capacity display. LSI's supercap-based parts (CV series)
report their data using the same interface as battery-based parts,
except that they do not include the capacity stats (state of charge,
cumulative charge cycles, etc.)
