Always set the magic sequence when we write, rather than trusting the
previously read boot code to do so.
Use explicit encoding/decoding of little endian disk image.
Remove a comment which was OBE.
Change the test vector for "fdisk -I" to reflect that there is a magic
sequence in the result now.
Add test case for "fdisk" which reads the image back.
At least for the two test-cases this program now gives the same result
on sparc64 as on i386. The lack of an installed /boot/mbr on sparc64
raises an (un)interesting question.
doesn't have a process group, which can occur if you're working with
a custom init that doesn't set up a full tty context. Rather than
refusing to reboot, ignore ESRCH from the kill attempt in reboot(8).

This fulfills the host requirements for userland support by
way of the setsockopt() IP_EVIL_INTENT message.
There are three sysctl tunables provided to govern system behavior.
net.inet.ip.rfc3514:
Enables support for rfc3514. As this is an
Informational RFC and support is not yet widespread
this option is disabled by default.
net.inet.ip.hear_no_evil
If set the host will discard all received evil packets.
net.inet.ip.speak_no_evil
If set the host will discard all transmitted evil packets.
The IP statistics counter 'ips_evil' (available via 'netstat') provides
information on the number of 'evil' packets recieved.
For reference, the '-E' option to 'ping' has been provided to demonstrate
and test the implementation.
- Correct some problems with packet construction.

My previous changes tried to mess around with 'datalen' instead of
modifying 'phdr_len'.
I'm including this nice ASCII diagram (from Maxim) to further clarify things
in CVS history.

when WARNS was increased recently, but __printf0like() has been
temporarily disabled for 8 months.
Fixed related style bugs (disordered declaraction and silly type for
maxpayload -- assume 16-bit ints like the rest of ping.c).
- Use it in atacontrol(8) when listing ATA devices instead of
stopping at the first ENXIO received.
This makes atacontrol list work on my sparc64 where the two ATA
channels I have are numbered 2 and 3.

This is aimed at creating floppies during cross-releases.
For different endianness machines, a tool like bswapfs(8)
is necessary to make the generated floppies readable on
the target machine. While here, fixed unaligned access
on Alphas.
Tested on: i386, alpha
