0cfae925d2e31a7d7613a6fb60aa58b38ec2b61e nbd/server: refactor negotiation functions parameters
Instead of passing currently negotiating option and its length to
many of negotiation functions let's just store them on NBDClient
struct to be state-variables of negotiation phase.
This unifies semantics of negotiation functions and allows
tracking changes of remaining option length in future patches.
Asssert that optlen is back to 0 after negotiation (including
old-style connections which don't negotiate), although we need
more patches before we can assert optlen is 0 between options
during negotiation.
