Remove SMB_time and SMB_date record types

This makes a change to the record for smb1-negotiate-response as well.
Times and dates are two 2-byte sections, not three. Switch the parsing
to just use two uint16s, and pass those into the lanman time conversion
function.

+
+  * cluster/zeromq: Fix Cluster::subscribe() block if not initialized (Arne Welzel, Corelight)
+
+    If Cluster::init() hasn't been invoked yet, Cluster::subscribe() with the
+    ZeroMQ backend would block because the main_inproc socket didn't
+    yet have a connection from the child thread. Prevent this by connecting
+    the main and child socket pair at construction time.
+
+    This will queue the subscriptions and start processing them once the
+    child thread has started.
