The existing ELF image activator requires the brandinfo to provide such
a string unconditionally, even if the executable format in question
doesn't use this type of branding. Skip matching when it's a null
pointer.

I think this message is not very useful for end user. Also its formatting
does not match other messages printed at that time. Those who really need
this information can always find it in `camcontrol negotiate daX -v`.

This way we can avoid blocking the whole queue in the low memory
situations. It's better to sacrifice some I/O performance by not doing
the aggregation than to add an indefinite wait for more memory.

This is done so that the thread state changes during the switch
are not confused with the thread state changes reported when the thread
spins on a lock.
Here is an example, three consecutive entries for the same thread (from top to
bottom):
KTRGRAPH group:"thread", id:"zio_write_intr_3 tid 100260", state:"sleep", attributes: prio:84, wmesg:"-", lockname:"(null)"
KTRGRAPH group:"thread", id:"zio_write_intr_3 tid 100260", state:"spinning", attributes: lockname:"sched lock 1"
KTRGRAPH group:"thread", id:"zio_write_intr_3 tid 100260", state:"running", attributes: none
The above trace could leave an impression that the final state of
the thread was "running".
After this change the sleep state will be reported after the "spinning"
and "running" states reported for the sched lock.

Newbus handles multiple equally named device classes without problems,
so there is no reason to use slightly cryptic "<foo>_shdci" for them.
In contrast, the driver module name must be unique, so "<foo>_shdci"
is the right name for it.

matches static binaries.
Interpretation of the 'static' there is that the binary must not
specify an interpreter. In particular, shared objects are matched by
the brand if BI_CAN_EXEC_DYN is also set.
This improves precision of the brand matching, which should eliminate
surprises due to brand ordering.
Revert r315701.

Prevent possible races in the pf_unload() / pf_purge_thread() shutdown
code. Lock the pf_purge_thread() with the new pf_end_lock to prevent
these races.
Use a shared/exclusive lock, as we need to also acquire another sx lock
(VNET_LIST_RLOCK). It's fine for both pf_purge_thread() and pf_unload()
to sleep,

Similar to the change for sendmsg(), create a pointer size independent
implementation of recvmsg() and let cloudabi32 and cloudabi64 call into
it. In case userspace requests one or more file descriptors, call
kern_recvit() in such a way that we get the control message headers in
an mbuf. Iterate over all of the headers and copy the file descriptors
to userspace.
CloudABI executables are statically linked and don't have an
interpreter. Setting the interpreter path to NULL used to work
previously, but r314851 introduced code that checks the string
unconditionally. Running CloudABI executables now causes a null pointer
dereference.
Looking at the rest of imgact_elf.c, it seems various other codepaths
already leaned on the fact that the interpreter path is set. Let's just
go ahead and pick an obviously incorrect interpreter path to appease
imgact_elf.c.

Reduce the potential amount of code duplication between cloudabi32 and
cloudabi64 by creating a cloudabi_sock_recv() utility function. The
cloudabi32 and cloudabi64 modules will then only contain code to convert
the iovecs to the native pointer size.
In cloudabi_sock_recv(), we can now construct an SCM_RIGHTS cmsghdr in
an mbuf and pass that on to kern_sendit().
This will provide a slightly better smoking gun than just stating
"can't remove non-dynamic nodes!" when calling sysctl_ctx_free(9)
and sysctl_remove_{name,oid}(9) with a non-dynamic (likely
static) sysctl.

Because of integer types, the timeout calculation result was limited to
INT_MAX / (1000 * hz) seconds. For systems with hz=10000, this is only 215
seconds. Perform the calculation with 64-bit math to allow sleeping for the
full INT_MAX / hz interval (215000 seconds on such hz=10000 systems).

We must ensure there's space for the terminating null in the temporary
buffer in imgact_binmisc_populate_interp().
Note that there's no buffer overflow here because xbe->xbe_interpreter's
length and null termination is checked in imgact_binmisc_add_entry()
before imgact_binmisc_populate_interp() is called. However, the latter
should correctly enforce its own bounds.

Let firmware do its best first, and if it can't, try software recovery.
I would remove software timeout handler completely, but found bunch of
complains on command timeout on sparc64 mailing list few years ago, so
better be safe in case of interrupt loss.
