Commit 774a36851e fixed the NFS server so that it could handle
ERELOOKUP returns from VOP calls by redoing the operation/RPC.
However, for NFSv4.0, redoing an Open would increment
the open_owner's seqid multiple times, breaking the protocol.
This patch sets a new flag called ND_ERELOOKUP on the RPC when
a redo is in progress. Then the code that increments the seqid
avoids the seqid increment/check when the flag is set, since
it indicates this has already been done for the Open.
r367672 modified UFS such that certain VOPs, such as
VOP_CREATE() will intermittently return ERELOOKUP.
When this happens, the entire system call, or NFS
operation in the case of the NFS server, must be redone.
This patch adds that support to the NFS server by rolling
back the state of the NFS request arguments and NFS
reply arguments mbuf lists to the condition they were
in before the operation and then redoing the operation.

It's unclear how this hasn't failed many builds before now, since it should

[PowerPC] Do not emit HW loop when TLS var accessed in PHI of loop
exit
If any PHI nodes in loop exit blocks have incoming values from the
loop that are accesses of TLS variables with local dynamic or general
dynamic TLS model, the address will be computed inside the loop.
Since this includes a call to __tls_get_addr, this will in turn cause
the CTR loops verifier to complain. Disable CTR loops in such cases.

Previously having ficl/liblua in LIB32LIST with their respective option
turned OFF would be relatively harmless, as we wouldn't act on it unless we
were building the non-32 variant. As of ac5f382a9d, however, these are
now used for dependencies in some cases and must reflect what's actually
going to be built.
The change to kern_jail_set that was supposed to "also properly clean
up when attachment fails" didn't fix a memory leak but actually caused
a double free. Back that part out, and leave the part that manages
allprison_lock state.
Support for fractional seconds has become much more widespread since

The cpuset(2) tests should be run as root (require.user properly set) with
>= 3 cpus for maximum coverage. All tests that want to modify the cpuset
don't assume any particular cpu layout (i.e. the first cpu may not be 0, the
last may not be first + count) and the following scenarios are tested:
1.) newset: basic execute cpuset() to grab a new cpuset, make sure the
assigned cpuset then has a different ID.
2.) transient: create a new cpuset then assign the process its original
cpuset, ensuring that the one we created is now gone.
3.) deadlk: test assigning an anonymous mask, then resetting the process
base affinity with 1-cpu overlap w.r.t. the anonymous mask and with
0-cpu overlap w.r.t. the anonymous mask.
4.) jail_attach_newbase: process attaches to a jail with its own
cpuset+mask (e.g. cpuset -c -l 1,2 jail -c path=/ command=/bin/sh)
5.) jail_attach_newbase_plain: process attaches to a jail with its own
cpuset (e.g. cpuset -c jail -c path=/ command=/bin/sh)
6.) jail_attach_prevbase: process attaches to a jail with the containing
jail's root cpuset (e.g. jail -c path=/ command=/bin/sh)
7.) jail_attach_plain: process attaches to a jail with the containing jail's
root cpuset+mask.
8.) badparent: creates a new cpuset and modifies the anonymous thread mask,
then setid's back to the original and checks that cpuset_getid() returns

buildworld already runs the stand build in parallel[1], so make it easier to
identify ordering issues by properly establishing dependencies or adding
.WAIT where needed.
Everything in stand/ relies on libsa, either directly or indirectly, because
libsa build is where the stand headers get installed and it gets linked in
most places.
Interpreters depend on their libs, machine dirs usually depend on top-level
libs that are getting built and at least one of the interpreter flavors.
For i386, order btx/libi386/libfirewire before everything else using a
big-ol-.WAIT hammer. btx is the most common dependency, but the others are
used sporadically. This seems to be where the race reporting on the mailing
list is- AFAICT, the following sequence is happening:
1.) One of the loaders gets built based on stale btx/btxldr
2.) btx/btxldr gets rebuilt
3.) installworld triggers loader rebuild because btx was rebuilt after
This seems like the most plausible explanation, as they've verified system
time and timestamps.
While we're here, let's switch stand/ over to a completely parallel build so
we can work out these kinds of issues in isolation rather than in the middle
of a larger build.

An 8MB max stack size is quite limiting in today's world, and in-fact is
the *default* stack size for almost every other arch (including mips).
Raise the default to 4MB (should be pretty reasonable) and the max to 64MB.
NetBSD made a similar move back in 2015 and raised MAXDSIZ to 1856 at the
same time, so let's just roll that in as well. They later lowered it, but
eventually raised it back to 1856 in order to build rust.
This was noticed while looking at qemu-bsd-user's default stack sizes and
growth behavior (or lack thereof).

When a break-to-debugger is triggered, kdb will grab the console and vt(4)
will generally switch back to ttyv0. If one issues a continue from the
debugger, then kdb will ungrab the console and the system rolls on.
This change adds a perhaps minor feature: when we're down to grab == 0 and
if vt actually switched away to ttyv0, switch back to the tty it was
previously on before the console was grabbed.
The justification behind this is that a typical flow is to work in
!ttyv0 to avoid console spam while occasionally dropping to ddb to inspect
system state before returning. This could easily enough be tossed behind
a sysctl or something if it's not generally appreciated, but I anticipate
indifference.

Note that loader_conf_files may be specified in a loader.conf.d config
