diskless problems

[Danny Braniss]

while the subject is being revived, there are some changes/additions I
made to libstand/bootp.c, it exports all the dhcp tags so that
they are available to rc.diskless? or rc.d/initdiskless via kenv
check out

these are a bit date, but the uptodated stuff is actively being used here,
so if there is some interest i could update it.
