The GCC developers separated out the configure header between libU77 and
libI77 and FreeBSD didn't keep up with the change. So now this header needs
to be a superset of both sublib's configuration specification.
Notably this commit causes ftruncate(), fseeko(), and ftello() to be used.

rarpd clobbered any AF_INET information already configured for a given
interface name, so interfaces with more than one IP address made rarpd
listen only for the last address out of all IP aliases.
I changed this, so that AF_LINK information is always collected first
(to ensure the interface name gets its link-layer address associated),
but while looking for AF_INET addresses, the configuration is cloned
if there has already been one IP address seen for that interface name.
Thus, rarpd now effectively listens on all subnets.

it checked for rt == NULL after dereferencing the pointer).
We never check for those events elsewhere, so probably these checks
might go away here as well.
Slightly simplify (and document) the logic for memory allocation
in rt_setgate().
The rest is mostly style changes -- replace 0 with NULL where appropriate,
remove the macro SA() that was only used once, remove some useless
debugging code in rt_fixchange, explain some odd-looking casts.
implementation taken directly from OpenBSD.
I've resisted committing this for quite some time because of concern over
TIME_WAIT recycling breakage (sequential allocation ensures that there is a
long time before ports are recycled), but recent testing has shown me that
my fears were unwarranted.
TIME_WAIT recycling cases I was able to generate with http testing tools.
In short, as the old algorithm relied on ticks to create the time offset
component of an ISN, two connections with the exact same host, port pair
that were generated between timer ticks would have the exact same sequence
number. As a result, the second connection would fail to pass the TIME_WAIT
check on the server side, and the SYN would never be acknowledged.
I've "fixed" this by adding random positive increments to the time component
between clock ticks so that ISNs will *always* be increasing, no matter how
quickly the port is recycled.
Except in such contrived benchmarking situations, this problem should never
come up in normal usage... until networks get faster.
No MFC planned, 4.x is missing other optimizations that are needed to even
create the situation in which such quick port recycling will occur.
- Merge support for numeric keys 1-5 from boot0.s
- Fix _PRTEND for the case of more than 2 sectors.
- Move the code to set the drive number up before we try to load in the rest
of boot0 off of the disk.
- Expand the OS name table to recognize more windows partitions and rename
the NT entry to 'Windows NT/XP'.

figure out why this is happening later.

This will quiet down the bootverbose case when using an ACU which
does brute force discovery of the physical and logical devices.
