some nameserver proposal bits:

unwind.8: point to resolvd(8) for autoconf sources
unwind.conf.5: order preferred list by order of preference
resolvd.8: reformat to read better
route.8: no need to discuss unwind in the nameserver command
umb.4 + sppp.4: note the sending of nameserver proposals

the umb/sppp text is from claudio
tobhe confirmed iked sending proposals when configured to do so

much assistance and ok: florian claudio
