general cleanup of the API. The entire API now consists of two functions
similar to the pre-KSE API. The suser() function takes a thread pointer
as its only argument. The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0. The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

- Make sure the interface is UP and RUNNING in fddi_input().
- Reorder and comment packet tests in fddi_input().
- Call if_attach() in fddi_ifattach().
- Test for a valid return from ifaddr_byindex().
- Use struct fddi_header where appropriate.
- Use bcopy() rather than memcpy().
- Use FDDI_ADDR_LEN macro instead of ETHER_ADDR_LEN macro.
- Add loadable module support.
- Use FDDI_ADDR_LEN rather than a magic number or a sizeof().
- Hide distracting sizeof() behind FDDI_HDR_LEN macro.
- Don't use sizeof(struct llc) in areas where we mean LLC_SNAPFRAMELEN.

that causes a machine to panic when the kernel PPP / DEFLATE code is used.
1.11 moved a ZFREE to a point after the structural members were clobbered
by stores into a union'd structure.
This commit fixes the bug and adds a big whopping comment to make sure
the code isn't 'cleaned up' again :-)
Ian Dowse came up with the same patch independantly 68 seconds before I
did, talk about Karma!
I would also like to thank Eugene Grosbein for marathon work in tracking the
problem down by udpating his -stable based on date over and over again
to close in on the commit that caused his crashes.

To enable. Just like ipfw(8) bridging, only input packets are filtered
in the bridge. Filtering works just like in the IP layer, ipf(8)
first, then ipfw(8). And just like in the IP layer, both are
independent, one need not be run to use the other. (Note: This will
not work in, but doesn't break, the bridge.ko module. The ipl.ko
module would need to be fixed before that is worth worrying about.)

currently supported for backwards compatability, but will probably be

New locks are:
- pgrpsess_lock which locks the whole pgrps and sessions,
- pg_mtx which protects the pgrp members, and
- s_mtx which protects the session members.
Please refer to sys/proc.h for the coverage of these locks.
Changes on the pgrp/session interface:
- pgfind() needs the pgrpsess_lock held.
- The caller of enterpgrp() is responsible to allocate a new pgrp and
session.
- Call enterthispgrp() in order to enter an existing pgrp.
- pgsignal() requires a pgrp lock held.

might try and keep using the old address until their arp table
entry times out and the address is refreshed.
Maybe this ought to be done for INET6 addresses as well but i have
no idea how to do it. It should be pretty straightforward though.

o Remove unused __uint16_swap_uint32() from i386's <machine/endian.h>.
o Remove prototypes for non-existent bswapXX() functions.
o Include <machine/endian.h> in <arpa/inet.h> to define the
POSIX-required ntohl() family of functions.
o Do similar things to expose the ntohl() family in libstand, <netinet/in.h>,
and <sys/param.h>.
o Prepend underscores to the ntohl() family to help deal with
complexities associated with having MD (asm and inline) versions, and
having to prevent exposure of these functions in other headers that
happen to make use of endian-specific defines.
o Create weak aliases to the canonical function name to help deal with
third-party software forgetting to include an appropriate header.
o Remove some now unneeded pollution from <sys/types.h>.
o Add missing <arpa/inet.h> includes in userland.
