vmd(8): implement zero-copy operations on virtqueues.
The original virtio device implementation relied on allocating a
buffer on heap, copying the virtqueue from the guest, mutating the
copy, and then overwriting the virtqueue in the guest.
While the approach worked, it was both complex and added extra
overhead. On older hardware, switching to the zero-copy approach
can show a noticeable performance improvement for vionet devices.
An added benefit is this diff also reduces the amount of code in
vmd, which is always a welcome change.
In addition, change to talking about the queue pfn and not "address"
as the virtio-pci spec has drivers provide a 32-bit value representing
the physical page number of the location in guest memory, not the
linear address.

To allow the kernel to be loaded at arbitrary physical addresses (and

use stoeplitz to generate a hash/flowid for state keys.
the hash will be used to partition work in pf and pfsync in the
future, and right now it is used as the first comparison in the rb
tree state lookup.
using stoeplitz means that pf will hash traffic the same way that
hardware using a stoeplitz key will hash incoming traffic on rings.
stoeplitz is also used by the tcp stack to generate a flow id, which
is used to pick which transmit ring is used on nics with multiple
queues too. using the same algorithm throughout the stack encourages
affinity of packets to rings and softnet threads the whole way
through.
using the hash as the first comparison in the state rb tree comparison
should encourage faster traversal of the state tree by having all
the address/port bits summarised into the single hash value. however,

Invalidate ugen(4) knote lists after device detach
This prevents the kernel from crashing when a ugen(4) device is detached

rework the synchronisation around suspend/resume.
the idea is that access to vmm from userland is gated by the vmm_softc
sc_status field, and then accounted for by the refcnt. you take a read
lock to check the gate, and if it is open then you can take a reference
and do your thing. once you've finished the work then you rele the
refcnt on the way out of the ioctl handler.
the suspend code takes a write lock to close the sc_status gate,
and then uses refcnt_finalise to wait for things in the ioctl handler
to get out.
on resume, the code takes the write lock, sets the refcnt up again for
userland to use, and then opens the gate.

move pf_state_item and pf_state_key structs from pfvar.h to pfvar_priv.h.
both of these are kernel private data structures and do not need
to be visible to userland. moving them to pfvar_priv.h makes this
explicit, and makes it leass scary to tweak them in the future.
