A logic bug in remove_protocol() meant that it would remove (leak) all
structures in the list preceding the one intended for removal.

This check eliminates infinite loop of MTU change / link flap / lease verification / MTU change / link flap etc.
in case of some NIC drivers like em(4) or igb(4).
N.B.: obsolete u_int16_t is used in consistency with the rest of the file.

- add static in a number of places
- initialize __progname rather than rely on magical extern values
- use nitems() instead of manually spelling it out
- unshadow 'idi'
- teach 'error' that it is '__dead2'
- add missing 'break'
Mostly const-correctness fixes. There were also some variable-shadowing,
unused variable, and a couple of sockaddr type-correctness changes. I also had
trouble with cast-align warnings. I was able to prove that one of them was a
false positive. But ultimately I had to disable the warning program-wide to
deal with the others.

Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
dhclient(8) is failing during boot to connect to the syslog service, because
syslog daemon is started after dhclient(8). This can be reproduced by stooping
syslog daemon and ktrace the dhclient or use kern.trap_enotcap sysctl and boot
the machine. Using the Casper syslog service fix the problem.

The offending code has been dead ever since the import from OpenBSD in
r195805. OpenBSD later deleted that entire function.

the BIOCSETIF ioctl.
The kernel always copies an entire struct ifreq and IPv4 addresses will
always fit in an ifreq.
On systems with pointers larger than 64-bits, the computed size will be
less than the size of struct ifreq, potentially resulting in the kernel
attempting to copyin memory from outside the allocation.

Make dhclient set interface MTU if it was provided.
This version implements MTU setting in dhclient itself before it runs
dhclient-script.
