Because of how breadn -> bufstrategy -> g_vfs_strategy are currently
implemented, bread on devvp always expects DEV_BSIZE block size.
Thus, devvp bo_bsize must always be DEV_BSIZE irrespective of media
properties or filesystem implementation details.

Rather than remove it for all architectures (which was a botch in
r205845), remove it only for arm and mips until that can be sorted out.

to support various storage boxes which really aren't active-active.
We only write the label on the *first* provider. For all other providers
we just "add" the disk. This also allows for an "add" verb.
A usage implication is that you should specificy the currently active
storage path as the first provider.
Note that this does not add RDAC-like functionality, but better allows for
autovolumefailover configurations (additional checkins elsewhere will support
this).

o Don't build vpo and syscons on mips or arm either
o Add a section for mips and arm breakages, and document why.
This is easier than opting in on all the other architectures:
# no BUS_SPACE_UNSPECIFIED: bce, bwi, bwn, mfi, mpt, siba_bwn
# No barrier instruction support (specific to this driver): sym
# no uart_cpu_$MACHINE_ARCH: uart
(mips has, by inspection, the same issues as arm, so ditto for it)

This patch has two fixes for potential kernel panics (one wrong
index, one access to the wrong lock) and two fixes to wrong logic
in a conditional. The potential panics are also on stable/8,
so I am going to MFC the fix quickly.
- Repeating events which span multiple years (because of -A, -B or
just the three days before the end of the year).
- Support for lunar events (full moon, new moon) and solar events
(equinox and solstice, chinese new year). Because of this, the
options -U (UTC offset) and -l (longitude) are available to
compensate if reality doesn't match the calculated values.

A nice thing about POSIX 2008 is that it finally standardizes a way to
obtain file access/modification/change times in sub-second precision,
namely using struct timespec, which we already have for a very long
time. Unfortunately POSIX uses different names.
This commit adds compatibility macros, so existing code should still
build properly. Also change all source code in the kernel to work
without any of the compatibility macros. This makes it all a less
ambiguous.
I am also renaming st_birthtime to st_birthtim, even though it was a
local extension anyway. It seems Cygwin also has a st_birthtim.
parser. This merge does not change any API and should not break any
native or thirdparty applications.
Changes include:
* Merge multiple report ID support and other improvements from kernel
HID parser.
* Ignore rid argument in hid_start_parser, parse all the report items since
we now support multiple report ID.
* Skip report ID byte in hid_get_data() and set report ID byte in
hid_set_data(), if report ID is non-zero.
* Reimplement hid_get_report_id: instead get report id from uhid device
(which is always 0), try parsing the report descriptor and return the
first report ID encountered.

o Switch to ITANIUM2 has the cpu. This has absolutely no effect
on the code, but makes for a better example.
o Drop COMPAT_FREEBSD6. We're tier 2, so you're supposed to run
8-stable or newer.
o Add PREEMPTION. It works now.
o Remove HWPMC_HOOKS. We don't have support for hwpmc yet.
o Add a bunch of new devices: atapist, hptiop, amr, ips, twa, igb,
ixgbe, ae, age, alc, ale, bce, bfe, et, jme, msk, nge, sk, ste,
stge, tx, vge, axe, rue, udav, fwip, and all USB serial.
o Remove "legacy" devices: le, vx, dc, pcn, rl, sis.

to give default behaviour. Remove <machine/nexusvar.h> as well,
because there's nothing in it that's being used.
- add some new hardware support for 82599
- Big change to interrupt architecture, it now
uses a queue which contains an RX/TX pair as
the recipient of the interrupt. This will reduce
overall system interrupts/msix usage.
- Improved RX mbuf handling: the old get_buf routine
is no longer synchronized with rxeof, this allows
the elimination of packet discards due to mbuf
allocation failure.
- Much simplified and improved AIM code, it now
happens in the queue interrupt context and takes
into account both the traffic on the RX AND TX
side.
- variety of small tweaks, like ring size, that have
been seen as performance improvements.
- Thanks to those that provided feedback or suggested
changes, I hope I've caught all of them.
