Nicholas J. Kain
5a38e49a81 Update get_option() to use the function from busybox's udhcp variant; 
it's much easier to read.  The original one is indecipherable, and thus
it is difficult to verify correctness.

Nicholas J. Kain
faa56bb616 Make change_listen_mode() create a new socket instantly rather than
