[ISC-Bugs #20265] [ISC-Bugs #20259] minor cleanup
[ISC-Bugs #20263] add text describing some default values
[ISC-Bugs #20193] single quotes at the start of a line indicate a control
line to nroff, escape them if we actually want a quote.
[ISC-Bugs #18916] sync the pointer to web pages amongst the different docs
Hopefully James does, so he can replace these with the nroff.
I just used:
memcpy(ipaddrstring->value, &convaddr.s_addr, 4);
for the byte order thingy. I'm hoping this is right. inet_pton will
spit out the address in network byte order, and Ted says that
dhcpctl_set_value is expecting it in network byte order, also.
