rc.d/routing: Silence errors for loopback routes
_loopback entry in `static_routes` ensures a loopback route
exists in all routing tables.
However, loopback routes may already be added by the kernel.
Therefore, re-adding them triggers an `EEXIST` error on every boot.
This change suppresses those harmless errors.

tests: Add pjdfstest integration
Use ATF to wrap the new reimplementation of pjdfstest that came out of
GSOC 2022, now available in the ports tree as filesystems/pjdfstest.
So far I added tests for UFS (with several different option
combinations), tmpfs and ZFS, plus ZFS+nullfs. All of these create a
memory disk, initialize the filesystem, and point the pjdfstest
executable at it.
In the future it would be good to add tests for at least NFS and p9fs.

uart: Add support for the Intel XScale controller
The ns8250 driver avoids clearing IER bit 0x10 to account for the
split "receiver time-out interrupt enable" bit, but it never sets
it in `ier_rxbits` even though a comment in `ns8250_init` implies so.
Fix this by setting `IER_RXTMOUT` if we've matched an XScale uart.

sockets: plumb SO_PASSRIGHTS into *sockopt(2)
This is a little different than the others in that it's not valid for
anything but unix(4) sockets. New cases were added that jump into the
more standard case out of a light preference for not taking advantage of
case FALLTHROUGH with the additional logic- it doesn't scale very well
for new cases added that might be slightly special, so we might as well
just add the labels up-front.

socket: remove tautological condition in so_unsplice()
so2rele was introduced in 1000cc4a0d3 and it was necessary there, but
the cleanup in a837d1fe49e0255 rendered it redundant if our own KASSERT
is to be believed: we've asserted that `so2->so_splice_back == sp` and
`sp` has been dereferenced above, so there's no condition left where
we shouldn't release the socket reference at the end. Indeed, the
change in so_splice() to NULL out sp->dst removes that possible state of
a partially constructed splice: if sp->dst is set, it has been ref'd.

unix: implement basic SO_PASSRIGHTS functionality
With exception to sockopt functionality, implement the so_options flag
in unix(4) itself. The general argument for the flag is that SCM_RIGHTS
can be used maliciously for, e.g., a DoS that the receiving side can't
avoid if it is expecting other control messages.
This option gives the receiver a way to disable SCM_RIGHTS on the
sender-side, surfacing an EPERM to them instead. This seems to match
the semantics that Linux offers.
If an SCM_RIGHTS was already sent before we disabled SO_PASSRIGHTS, then
a subsequent recvmsg(2) will silently discard any in-flight files. This
has the downside of punting a file with the potential to hang over to
the deferred-close task, but perhaps usage of the option would
discourage folks from attempting to take advantage of that possibility
anyways.
Various manpages updated to describe the new behavior.

stand: Bulk operations on each gfxfb_blt if shadow buffer enabled
Previously, gfxfb_blt flushed the framebuffer on every call. Since a
single drawing operation may invoke gfxfb_blt multiple times, this can
result in unnecessary flushes.
Instead, write updates to the shadow buffer (when present) and mark the
affected area as dirty. Flushing is deferred so multiple gfxfb_blt calls
can be coalesced into a single update. As before, only the dirty region
is flushed.
This fixes the slow bootloader problem in some platforms.

virtual_oss(8): Properly cleanup cuse(3)virtual_oss(8) does not currently keep track of the cuse(3) it creates,
nor does it destroy any of them on exit, except for the control device.
This is harmless if virtual_oss(8) is killed after all audio streams
have been shut down, but if it's killed during I/O, the process hangs
and/or goes into uninterruptible sleep state.
To fix this, have pointers to all cuse(3) devices, and explicitly
destroy them on exit. Also make sure we don't leak memory in
dup_profile().

nfs_nfsdserv.c: Fix setting of birthtime for some ZFS pools
Some ZFS pools do not support va_birthtime and will return
EINVAL when a VOP_SETATTR() of it is attempted. The MacOS
NFSv4 client sets va_birthtime (TimeCreate) in the same
Setattr with ctime/mtime and other attributes after a new
file is created. The EINVAL failure leaves these new files
messed up (mode == 0).
This patch pretends the setting of TimeCreate succeeded if
ctime/mtime were also set in the same Setattr RPC, which
resolves the problem for the MacOS client.
If this fix is not sufficient, a new pathconf name to detect
if a file system supports birthtime may be needed.

arm64: Add an initial GICv5 ITS driver
Add a driver to support the GICv5 interrupt translation service (ITS).
The ITS is responsible to handling ITS events & translating them to an
interrupt to be delivered to the interrupt routing service (IRS).
An example event is a MSI or MSI-X is delivered. The ITS will generate
an LPI depending on which device sent the interrupt and the value the
device wrote.
This is a similar concept to the GICv3 ITS, however the implementation
details are different so it needs a new driver.
