This change does the following for the scripts that run up through
FILESYSTEMS (the default early_late_divider):
1. Move sysctl to run first
2. Move as many BEFOREs to REQUIREs as possible.
3. Minor effect, move hostid_save from right before mdconfig to right
after.
A lot of the early scripts make use of sysctl one way or another so
running this first makes a lot of sense given that system-critical
values are often placed in sysctl.conf. (More details in original log.)
In addition to the changes from this revision, tweak a few other rcorder

A problem with respect to data read through the buffer cache for both
NFS clients was reported to freebsd-fs@ under the subject "NFS
corruption in recent HEAD" on Nov. 26, 2011. This problem occurred when
a TCP mounted root fs was changed to using UDP. I believe that this
problem was caused by the change in mnt_stat.f_iosize that occurred
because rsize was decreased to the maximum supported by UDP. This
patch fixes the problem by using v_bufobj.bo_bsize instead of f_iosize,
since the latter is set to f_iosize when the vnode is allocated, but
does not change for a given vnode when f_iosize changes.
In case ntp cannot resolve a hostname on startup it will queue the entry
for resolving by a child process that, upon success, will add the entry
to the config of the running running parent process.
Unfortunately there are a couple of bugs with this, fixed in various
later versions of upstream in potentially different ways due to other
code changes:
1) Upon server [-46] <FQDN> the [-46] are used as FQDN for later resolving
which does not work. Make sure we always pass the name (or IP there).
2) The intermediate file to carry the information to the child process
does not know about -4/-6 restrictions, so that a dual-stacked host
could resolve to an IPv6 address but that might be unreachable (see
r223626) leading to no working synchronization ignoring a IPv4 record.
Thus alter the intermediate format to also pass the address family
(AF_UNSPEC (default), AF_INET or AF_INET6) to the child process
depending on -4 or -6.
3) Make the child process to parse the new intermediate file format and
save the address family for getaddrinfo() hints flags.
4) Change child to always reload resolv.conf calling res_init() before
trying to resolve names. This will pick up resolv.conf changes or
new resolv.confs should they have not existed or been empty or
unusable on ntp startup. This fix is more conditional in upstream
versions but given FreeBSD has res_init there is no need for the
configure logic as well.

Given that sun4u uses sparc64/sparc64/ofw_machdep.c, use the sparc64
<machine/ofw_machdep.h> here also. This isn't exactly a clean approach
though as ofw_machdep.h also includes some prototypes for functions
that aren't actually shared between both architectures but just happen
to have the same interface. Given that the sun4v support actually is
dead and this is just to allow things to continue to compile it should
be okay though.
Hide IPv6 next header parsing warnings under the verbose sysctl
so people can possibly disable it when their consoles are flooded,
or enabled it for debugging.
If we detect an IPv6 fragment header and it is not the first fragment,
then terminate the loop as we will not find any further headers and
for short fragments this could otherwise lead to a pullup error
discarding the fragment.

PR: kern/145733
ipfw internally checks for offset == 0 to determine whether the
packet is a/the first fragment or not. For IPv6 we have added the
"more fragments" flag as well to be able to determine on whether
there will be more as we do not have the fragment header avaialble
for logging, while for IPv4 this information can be derived directly
from the IPv4 header. This allowed fragmented packets to bypass
normal rules as proper masking was not done when checking offset.
Split variables to not need masking for IPv6 to avoid further errors.
After r225032 fix logging in a similar way masking the the IPv6
more fragments flag off so that offset == 0 checks work properly.

While not explicitly allowed by RFC 2460, in case there is no
translation technology involved (and that section is suggested to
be removed by Errata 2843), single packet fragments do not harm.
There is another errata and further drafts under discussion to clarify
on these kinds of packets.
Meanwhile add a sysctl to allow disabling this behaviour again.
We will treat single packet fragment (a fragment header added
when not needed) as if there was no fragment header.
