Merge boot0.s and boot0sio.s into boot0_512.s controlled by "#ifdef SIO".
Add Makefile magic to generate boot0.s and boot0sio.s from boot0_512.s.
The compile boot0 and boot0sio have unchanged MD5 checksums.

(patch for /sys/dev/pci/pci.c needed for that) since pci_get_progif
uses the saved value for progif, not the one stored after we may have
changed from legacy mode to native PCI mode.
jail, which is less restrictive but allows for more flexible
jail usage (for those who are willing to make the sacrifice).
The default is off, but allowing raw sockets within jails can
now be accomplished by tuning security.jail.allow_raw_sockets
to 1.
Turning this on will allow you to use things like ping(8)
or traceroute(8) from within a jail.
The patch being committed is not identical to the patch
in the PR. The committed version is more friendly to
APIs which pjd is working on, so it should integrate
into his work quite nicely. This change has also been
presented and addressed on the freebsd-hackers mailing
list.

libufs, which only works for Charlie root.
This change reverts the introduction of libufs and moves the
check into the kernel. Since the f_fstypename is the same
for both ufs and ufs2, we check fs_magic for presence of
ufs2 and copy "ufs2" explicitly instead.

possible while maintaining compatibility with the widest range of TCP stacks.
The algorithm is as follows:
---
For connections in the ESTABLISHED state, only resets with
sequence numbers exactly matching last_ack_sent will cause a reset,
all other segments will be silently dropped.
For connections in all other states, a reset anywhere in the window
will cause the connection to be reset. All other segments will be
silently dropped.
---
The necessity of accepting all in-window resets was discovered
by jayanth and jlemon, both of whom have seen TCP stacks that
will respond to FIN-ACK packets with resets not meeting the
strict last_ack_sent check.

1) In pci.c, we need to check the child device's state, not the parent
device's state.
2) In acpi_pci.c, we have to run the power state change after the acpi
method when the old_state is > new state, not the other way around.

1. rt_check() cleanup:
rt_check() is only necessary for some address families to gain access
to the corresponding arp entry, so call it only in/near the *resolve()
routines where it is actually used -- at the moment this is
arpresolve(), nd6_storelladdr() (the call is embedded here),
and atmresolve() (the call is just before atmresolve to reduce
the number of changes).
This change will make it a lot easier to decouple the arp table
from the routing table.
There is an extra call to rt_check() in if_iso88025subr.c to
determine the routing info length. I have left it alone for
the time being.
The interface of arpresolve() and nd6_storelladdr() now changes slightly:
+ the 'rtentry' parameter (really a hint from the upper level layer)
is now passed unchanged from *_output(), so it becomes the route
to the final destination and not to the gateway.
+ the routines will return 0 if resolution is possible, non-zero
otherwise.
+ arpresolve() returns EWOULDBLOCK in case the mbuf is being held
waiting for an arp reply -- in this case the error code is masked
in the caller so the upper layer protocol will not see a failure.
2. arpcom untangling
Where possible, use 'struct ifnet' instead of 'struct arpcom' variables,
and use the IFP2AC macro to access arpcom fields.
This mostly affects the netatalk code.

- Fix some comments; remove numerous superfluous or outdated ones.
- Correctly pass on the requesting device when handing requests up
to the parent bus.
- Use the complete device name, including unit number, to build the
IOMMU instance name.
- Inline a function that was only used once, and was trivial.
consistently with the rest of the code, use IFP2AC(ifp) to access
the arpcom structure given the ifp.
In this case also fix a difference in assumptions WRT the rest of
the net/ sources: it is not the 'struct *softc' that starts with a
'struct arpcom', but a 'struct arpcom' that starts with a
'struct ifnet'
