After removing collation for [a-z] ranges in r302512, mimic system

re-apply r299908: zfsctl_snapdir_lookup: clear VV_ROOT of snapshot's root
The change has been undone in r301275 on the assumption that it was no
longer required. But that was incorrect, because in this case (and only
in this case) the snapshot root vnode is looked up before z_parent is
fixed up.

Reduce the set of things on the disc1 image to those on the bootonly image.
Notably, this removes the toolchain from the CD-ROM image (it remains on DVD

META_MODE: Don't require filemon(4) for mergemaster(8)/etcupdate(8)
New .meta files will be created without filemon data, but any future build

Fix problems in the FQ-PIE AQM cleanup code that could leak memory or
cause a crash.
Because dummynet calls pie_cleanup() while holding a mutex, pie_cleanup()
is not able to use callout_drain() to make sure that all callouts are
finished before it returns, and callout_stop() is not sufficient to make
that guarantee. After pie_cleanup() returns, dummynet will free a
structure that any remaining callouts will want to access.
Fix these problems by allocating a separate structure to contain the
data used by the callouts. In pie_cleanup(), call callout_reset_sbt()
to replace the normal callout with a cleanup callout that does the cleanup
work for each sub-queue. The instance of the cleanup callout that
destroys the last flow will also free the extra allocated block of memory.
Protect the reference count manipulation in the cleanup callout with
DN_BH_WLOCK() to be consistent with all of the other usage of the reference
count where this lock is held by the dummynet code.

mkimg(1): minor cleanups with argument order in calloc(3).
Generally the first argument in calloc is supposed to stand for a count
and the second for a size. Try to make that consistent. While here,
attempt to make some use of the overflow detection capability in
calloc(3).
If the hypervisor version is smaller than 4.6.0. Xen commits 74fd00 and
70a3cb are required on the hypervisor side for this to be fixed, and those
are only included in 4.6.0, so stay on the safe side and disable MSI-X
interrupt migration on anything older than 4.6.0.
It should not cause major performance degradation unless a lot of MSI-X
interrupts are allocated.

For multi-channel devices, once the primary channel is closed,
a set of 'rescind' messages for sub-channels will be delivered
by Hypervisor. Sub-channel MUST be freed according to these
'rescind' messages; directly re-openning sub-channels in the
same fashion as the primary channel's re-opening does NOT work
at all.
After the primary channel is re-opened, requested # of sub-
channels will be delivered though 'channel offer' messages, and
this set of newly offered channels can be opened along side with
the primary channel.
This unbreaks the MTU setting for hn(4), which requires re-
openning all existsing channels upon MTU change.
Despite the implication (process has pending signals -> the current
thread marked for AST and has TDF_NEEDSIGCHK set) is not true due to
other thread might manipulate its signal blocking mask, it should still
hold for the single-threaded processes. Enable check for the condition
for single-threaded case, and replicate it from userret() to ast() as
well, where we check that ast indeed has no signal to deliver.
Note that the check is under DIAGNOSTIC, it is not enabled for INVARIANTS
but !DIAGNOSTIC since it imposes too heavy-weight locking for day-to-day
used debugging kernel.

hyperv/stor: Save the response status and xfer length properly.
The current command response handling discards status and xfer
length unconditionally, so that all of the commands would be
considered successful, even if errors happened. When errors
really happens, this causes all kinds of wiredness, since the
buffer will not be filled on the host side and sense data will
be ignored.
Most of the time, errors do not happen, however, error does
happen for the request sent immediately after the disk resizing.
Discarding the SCSI status (SCSI_STATUS_CHECK_COND) and sense
data (capacity changes) prevents the disk resizing from working
properly.
This commit saves the response status and xfer length properly
for later use.

bhnd(4): Add bus pass-aware discovery of platform devices (PMU,
NVRAM, ChipCommon, etc).
This extends the existing handling of NVRAM core discovery to support
locating additional devices that may be attached either directly as real
cores, or indirectly via ChipCommon (e.g. bhnd_pmu).
When attached as a SoC root bus (as opposed to a bridged WiFi device),
the platform devices may not be attached until later bus passes,
necessitating delayed discovery/initialization.

2) Reduce [Cc]flag loop to WCHAR_MAX, WINT_MAX here includes WEOF which is
