Several bug fixes:

Several bug fixes:

1. In osrfRouterRun(): eliminate the counting of sockets.  Rely
on the traversal of the class list to cover all the active
sockets.  Otherwise we would enter an infinite loop if we had just
deleted a class with an active socket.

2. In osrfRouterClassHandleIncoming(): in the case of an error
message that we can't reroute to a different node, do a continue
instead of a return.  Otherwise we delay any further messages that
may be enqueued for the same class, and possibly skip them entirely.

Also, in the same scenario: free the message before continuing, in
order to avoid a memory leak, and clear the transaction id for the
logging routines.

3. In osrfRouterClassHandleBounce(): remove the dead node when it is the
last one left for its class.  Remove the class as well, since it is
no longer usable.  We had been leaving the dead node around, for no
good reason.
