This allows respecting -nostdinc, -nostdinc++ and -nostdlib before
making the decision to add in -isystem, etc. The -isystem flags
are problematic for building lib/libc++ and lib/libcxxrt which wants
to only use its own headers.
More information the need of these flags can be found at
https://gcc.gnu.org/ml/gcc/2016-03/msg00219.html
This also reverts r300873.

This is the same as the main build logic. GCC with a cross-compiler
requires using -isystem to =/usr/include to get the search order
correct.

Always create loopback routes on every fib, for both IPv4 and IPv6
etc/rc.d/routing
Create loopback IPv4 and IPv6 routes on every fib at boot. Revert
278302; now that all FIBs have IPv6 loopback routes, the
"route add -reject" commands won't fail.
tests/etc/rc.d/routing_test.sh
Greatly simplify static_ipv6_loopback_route_for_each_fib. It was
written under the assumption that loopback routes would be added to
a given fib by the kernel as soon as an interface is configured on
that fib. However, the logic can be much simpler now that we simply
add loopback routes to all fibs at boot. This also removes the need
to run the test as root, removes the restriction that
net.add_addr_allfibs=0, and removes the need to configure fibs in
kyua.conf.
Also, add a test case for IPv4 loopback routes

ZFS's configuration needs to be updated whenever the physical path for a
device changes, but not when a new device is introduced. This is because new
devices necessarily cause config updates, but only if they are actually
accepted into the pool.

Split vdev_geom_set_physpath out of vdev_geom_attrchanged. When
setting the vdev's physical path, only request a config update if
the physical path has changed. Don't request it when opening a
device for the first time, because the config sync will happen
anyway upstack.

Strip leading spaces off of a SCSI disk's reported serial number
when populating the CAM serial number. This affects the output of
"diskinfo -v" and the names of /dev/diskid/DISK-* device nodes,
among other things.
SPC5r05 says that the Product Serial Number field from the Unit
Serial Number VPD page is right-aligned. So any leading spaces are
not part of the actual serial number. Most devices don't left-pad
their serial numbers, but some do. In particular, the SN VPD page
that an LSI HBA emulates for a SATA drive contains enough
left-padding to fill a 20-byte field.

Add a note to UPDATING, because some users may have to update

of this function some day. In the meantime, there is code that contains
calls to this function (so the decl is needed), but have runtime checks to
avoid calling it in the non-INTRNG case.

indicate that threads are waiting for free pages to become available and
(2) to indicate whether a wakeup call has been sent to the page daemon.
The trouble is that a single flag cannot really serve both purposes, because
we have two distinct targets for when to wakeup threads waiting for free
pages versus when the page daemon has completed its work. In particular,
the flag will be cleared by vm_page_free() before the page daemon has met
its target, and this can lead to the OOM killer being invoked prematurely.
To address this problem, a new flag "vm_pageout_wanted" is introduced.

Both cd and xprt will be non-NULL after their respective malloc(9) wrappers are
called (mem_alloc and svc_xprt_alloc, which calls mem_alloc) as mem_alloc
always gets called with M_WAITOK|M_ZERO today. Thus, testing for them being
non-NULL is incorrect -- it misleads Coverity and it misleads the reader.
Remove some unnecessary NULL initializations as a follow up to help solidify
the fact that these pointers will be initialized properly in sys/rpc/.. with
the interfaces the way they are currently.
