This will allow end-users to move the binaries to different locations
after they've been built without having to rebuild the binaries with
the new paths

This allows to avoid extra network traffic when copying files on NTFS iSCSI
disks within one storage host by drag'n'dropping them in Windows Explorer
of Windows 8/2012. It should also accelerate Hyper-V VM operations, etc.

r262867 was described as fixing socket buffer checks for SOCK_SEQPACKET,
but also changed one of the SOCK_DGRAM code paths to use the new
sbappendaddr_nospacecheck_locked() function. This lead to SOCK_DGRAM
bypassing socket buffer limits.
bridges in strange ways, either rendering them unable to detect
insertion and removal events, or possibly unable to read from the
device behind the bridge.
This fixes at least one laptop, a Toshiba Tecra M5 with a Texas
Instruments PCxx12 (d=0x8039 v=0c104c) bridge. The very similar
Tecra M9 has the same bridge, but worked fine without this change.
The bridge chip has no I/O port BAR, and there is nothing in the spec
to suggest I/O decoding should be enabled; however enabling it fixes
the issue. Add an XXX comment to this effect.

We continue to use pmap_enter() for that. For unwiring virtual pages, we
now use pmap_unwire(), which unwires a range of virtual addresses instead
of a single virtual page.

expect (require) data on stdin. The effect of this is that, when
backgrounded, $! returns the pid of an Xdialog(1) instance instead of
an sh(1) instance -- the difference being a later kill of $! will reach
the Xdialog(1) instance whereas without the exec the kill succeeds on
the sh(1) instance leaving Xdialog(1) open.
It could be claimed that two things were reasonable protected by
Giant. One is vfsconf list links, which is converted to the new
dedicated sx vfsconf_sx. Another is vfsconf.vfc_refcount, which is
now updated with atomics.
Note that vfc_refcount still has the same races now as it has under
the Giant, the unload of filesystem modules can happen while the
module is still in use.

In dnode_children_t, use C99's "[]" idiom for declaring the variable
sized array dnc_children at the end of the structure.
This prevents the compiler from mistakenly optimizing away accesses
beyond the array's defined size.
