The DSCP_INVALID flag allowed callers to prevent socket-util from
modify the DSCP bits of newly created sockets. However, the two
really important callers (implementations of the controller and
manager tables) never used it. Furthermore, the other callers
would be fine always setting the DSCP bits to zero. This patch
removes the DSCP_INVALID option in an effort to simplify the code.

The changes allow the user to specify a separate dscp value for the
controller connection and the manager connection. The value will take
effect on resetting the connections. If no value is specified a default
value of 192 is chosen for each of the connections.

The vconn code is a relative fossil as OVS code goes. It was written
before we had really figured how code should fit together. Part of that
history is that it used poll_fd_callback() to register callbacks without
the assistance of other code. That isn't how the rest of OVS works now;
this code is the only remaining user of that function.
To make it more like the rest of the system, this code gets rid of the use
of poll_fd_callback(). It also adds vconn_run() and vconn_run_wait()
functions and calls to them from the places where they are now required.

This member is initialized, but nothing ever reads it, so get rid of it.

The in-band control code needs to know the IP and port of both ends of the
control connection. However, the vconn code was only reporting the local
address after the connection had already succeeded, which created a
chicken-and-egg problem. In practice we would fail to connect until the
switch went into fail-open, at which point the connection would go through.
Fortunately, we can get the local IP address right after we try to connect,
not just after the connection completes, so this commit changes the code
to do that.
This commit also breaks setting the remote IP and port into functions
separate from vconn_init(), which makes the code more readable.

Previously, rconn and vconn only allowed users to find out about the
remote IP address. This set of changes allows users to retrieve the
remote port, local IP, and local port used for the connection.
