intent); besides being reable now, this fixes (several!) bugs in
timeout calculation, which caused nbssn_rselect() to return
prematurely
put the timeout in separate variable declared on top, so that it's clear
where the value comes from
don't adjust timeout in smb_nbst_connect() - this made the timeout
too short if connect happened to be fast
(XXX perhaps reevaluate this later and put back in some other form)
bump NB_SNDQ/NB_RCVQ to 64k, and actually use the defines to set
snd/rcv buffer sizes
use #define for the snd/rcv timeo
some whitespace/KNF fixes
