Use memcpy for all little-endian architectures, sys/kern/md5c.c indicates
this should be safe for all currently supported LE archs.
Change the Encode and Decode functions for other archs to use le32toh()
and htole32() functions instead of explicit byte shuffling.
On sparc64 this gives md5(1) about 8% speed increase.
packet forwarding state ("annotations") during ip processing.
The code is considerably cleaner now.
The variables removed by this change are:
ip_divert_cookie used by divert sockets
ip_fw_fwd_addr used for transparent ip redirection
last_pkt used by dynamic pipes in dummynet
Removal of the first two has been done by carrying the annotations
into volatile structs prepended to the mbuf chains, and adding
appropriate code to add/remove annotations in the routines which
make use of them, i.e. ip_input(), ip_output(), tcp_input(),
bdg_forward(), ether_demux(), ether_output_frame(), div_output().
On passing, remove a bug in divert handling of fragmented packet.
Now it is the fragment at offset 0 which sets the divert status of
the whole packet, whereas formerly it was the last incoming fragment
to decide.
Removal of last_pkt required a change in the interface of ip_fw_chk()
and dummynet_io(). On passing, use the same mechanism for dummynet
annotations and for divert/forward annotations.
option IPFIREWALL_FORWARD is effectively useless, the code to
implement it is very small and is now in by default to avoid the
obfuscation of conditionally compiled code.
NOTES:
* there is at least one global variable left, sro_fwd, in ip_output().
I am not sure if/how this can be removed.
* I have deliberately avoided gratuitous style changes in this commit
to avoid cluttering the diffs. Minor stule cleanup will likely be
necessary
* this commit only focused on the IP layer. I am sure there is a
number of global variables used in the TCP and maybe UDP stack.
* despite the number of files touched, there are absolutely no API's
or data structures changed by this commit (except the interfaces of
ip_fw_chk() and dummynet_io(), which are internal anyways), so
an MFC is quite safe and unintrusive (and desirable, given the
improved readability of the code).
MFC after: 10 days
is appropriate to avoid using typeof/__typeof__. It is worth noting that
SWAP() is only ever used to swap pointer values so 'void *' assumptions would
have been acceptable, but I'd gladly pay you tuesday for a cheeseburger^W
cleaner interface today.

o Also, in vnode_pager_alloc(), remove an unnecessary re-initialization
of struct vm_object::flags and move a statement that is duplicated
in both branches of an if-else.

While I'm at it, make sure UFS_EXTATTR is not spelt FFS_EXTATTR.

instead add the newline when the pattern space is printed. Make the `G' and
`H' commands add a newline to the space before the data, remove bogus
addition of newline from `x' command.

Gcc 3.1's -O0 and -O1 actually optimized alignment for space, but we feel
it should optimize alignment for time like Gcc 2.95 used to. Optimization
for space should give 1-byte alignment on i386's, but doesn't quite.
xmalloc() and xrealloc() and the mixed usage of xmalloc in some .c's from
libiberty.a and other .c's from libreadline.so produces an unusable binary
on the Alpha.
While I am here, preventatively move other libs in the link order.

Updated release notes: libpcap-0.7.1, tcpdump-3.7.1.
Also do some markup fixes to recently-added items so that they don't
try to use entities for manpages that have been removed, in the spirit
of rev. 1.359.
