nanobsd. implement support for NanoBSD touching a file (and possibly
recording that fact) as well as replacing a directory with a symlink.
Also specify the default uname and gname for files and use that as a
/set command at the top of the generated METALOG file.
iscsi's shutdown_pre_sync prio was SHUTDOWN_PRI_FIRST which caused it to
run before other high priority handlers such as filesystems e.g. ZFS.
This meant the iscsi sessions where removed before the ZFS geom consumer
was closed, resulting in a panic from g_access calls on debug kernels
due to negative acr.
Instead use the same as the old iscsi_initiator SHUTDOWN_PRI_DEFAULT-1
which allows it to run before dashutdown etc but after filesystems.

On vm_page_rename failure, fix a missing object unlock and a double free of
a page.
First remove the old page, then rename into other page into first_object,
then free the old page. This avoids the problem on rename failure. This is
a little ugly but seems to be the most straightforward solution.
Tested with:
$ sysctl debug.fail_point.uma_zalloc_arg="1%return"
$ kyua test -k /usr/tests/sys/Kyuafile

Typical TLBs have 40-512 entries available. At some point, iterating
every single page in a requested invalidation range and issuing invlpg
on it is more expensive than flushing the TLB and allowing it to reload
on demand.
Broadwell CPUs have 1536 L2 TLB entries, so I've picked the arbitrary
number 4096 entries as a hueristic at which point we flush TLB rather
than invalidating every single potential page.

It was allowed before, but make it very explicit it is allowed now. And
prefer 'bool' to older types that were used for the same purpose -- int and
boolean_t.
Like with the C99 fixed-width types, use common sense when changing old

No igor regressions.

LLE structure is mostly unchanged during its lifecycle.
To be more specific, there are 2 things relevant for fast path
lookup code:
1) link-level address change. Since r286722, these updates are performed
under AFDATA WLOCK.
2) Some sort of feedback indicating that this particular entry is used so
we re-send arp request to perform reachability verification instead of
expiring entry. The only signal that is needed from fast path is something
like binary yes/no.
The latter is solved by the following changes:
1) introduce special r_skip_req field which is read lockless by fast path,
but updated under (new) req_mutex mutex. If this field is non-zero, then
fast path will acquire lock and set it back to 0.
2) introduce simple state machine: incomplete->reachable<->verify->deleted.
Before that we implicitely had incomplete->reachable->deleted state machine,
with V_arpt_keep between "reachable" and "deleted". Verification was performed
in runtime 5 seconds before V_arpt_keep expire.
This is changed to "change state to verify 5 seconds before V_arpt_keep,
set r_skip_req to non-zero value and check it every second". If the value
is zero - then send arp verification probe.
These changes do not introduce any signifficant control plane overhead:
typically lle callout timer would fire 1 time more each V_arpt_keep (1200s)
for used lles and up to arp_maxtries (5) for dead lles.
As a result, all packets towards "reachable" lle are handled by fast path without
acquiring lle read lock.
Additional "req_mutex" is needed because callout / arpresolve_slow() or eventhandler
might keep LLE lock for signifficant amount of time, which might not be feasible
for fast path locking (e.g. having rmlock as ether AFDATA or lltable own lock).

supported, revert to flushing only non-global entries, i.e. to the
pre-r291688 state. There is no need to flush global TLB entries,
since only global entries created during the previous iterations of
the loop could exist at this moment.
