bhyve.8: Update and rearrange to improve readability
bhyve's man page is a very long block of text that has grown to
proportions that make it hard to read. In particular, the level of
nesting of various content means man can no longer render the text in a
user-friendly way.
To remedy this:
- move the -s argument documentation into a separate section and
reformat the various arguments so they are consistent
- add documentation on how to use the -o config.dump feature
- make the listing of various arguments more consistent
- consolidated duplicate listings of TPM backends
- add an example for the config.dump feature
- fix various formatting inconsistencies.

Revert "nfsd: Fix NFSv4.1/4.2 Claim_Deleg_Cur_FH"
This reverts commit f300335d9aebf2e99862bf783978bd44ede23550.
It turns out that the old code was correct and it was wireshark
that was broken and indicated that the RPC's XDR was bogus.

nfscl: Revert part of commit 196787f79e67
Commit 196787f79e67 erroneously assumed that the client code for

It was actually wireshark that was broken and indicated

bitset: Add ORNOT macros
Macros to ANDNOT a bitset currently exist, but there are no ORNOT

nfscl: Clear out a lot of cruft related to B_DIRECT
There is only one place in the unpatched sources where B_DIRECT is
set in the NFS client and this code is never executed. As such, this patch
removes this code that is never executed, since B_DIRECT should never
be set.
During a IETF testing event this week, I saw a crash in ncl_doio_directwrite(),
but this function is only called if B_DIRECT is set.
I cannot explain how ncl_doio_directwrite() got called, but once this patch
was applied to the sources, the crash did not recur. This is not surprising,
since this patch deleted the function.

unionfs_lookup(): fix wild accesses to vnode private data
There are a few spots in which unionfs_lookup() accesses unionfs vnode
private data without holding the corresponding vnode lock or interlock.

install: Always use a temporary file.
Previously, we would only use a temporary file if explicitly asked to
with the `-S` option, and even then, only if the target file already
existed. This meant that an outside observer looking for the target
file might see a partial file, and might see the file disappear and
then reappear.
With this patch, we always use a temporary file, ensuring atomicity.
The downside is slightly increased disk usage. The upside is never
having to worry about, for instance, cron jobs randomly failing if
they happen to run simultaneously with `make installworld`.
The `-S` option is retained, partly for compatibility, and partly
to control the use of `fsync(2)`, which has a non-negligible cost
(approximately 10% increase in wall time for `make installworld`).

Fix MNT_IGNORE for devfs, fdescfs and nullfs
The MNT_IGNORE flag can be used to mark certain filesystem mounts so
that utilities such as df(1) and mount(8) can filter out those mounts by
default. This can be used, for instance, to reduce the noise from
running container workloads inside jails which often have at least three
and sometimes as many as ten mounts per container.
The flag is supplied by the nmount(2) system call and is recorded so
that it can be reported by statfs(2). Unfortunately several filesystems
override the default behaviour and mask out the flag, defeating its
purpose. This change preserves the MNT_IGNORE flag for those filesystems
so that it can be reported correctly.

Support ARP for 802 networks

802.5 Token Ring, but we don't support those.)
This was accidentally removed along with FDDI support in commit
0437c8e3b198, presumably because comments implied it was used only by
FDDI or Token Ring.

linux: ignore setsockopt(IPV6_RECVERR)
Under Linux, the socket options IP_RECVERR and IPV6_RECVERR are used to
receive socket errors via a dedicated 'error queue' which can be
retrieved via recvmsg(). FreeBSD does not support this functionality.
For IPv4, the sysctl compat.linux.ignore_ip_recverr can be set to 1 to
silently ignore attempts to set IP_RECVERR and return success to the
application, which is wrong, but is required for (among other things)
a functional DNS client in recent versions of glibc.
Add support for ignoring IPV6_RECVERR, controlled by the same sysctl.
This fixes DNS in Linux when using IPv6 resolvers.
