New vnnmap is constructed using the information from all the connected

The only place the outgoing connection needs to be stopped is when
there is a timeout when waiting for the connection to become writable.
Add a new function ctdb_tcp_node_connect_timeout() to handle this
case.
All of the other cases are attempts to establish a new outgoing
connection (initial attempt, retry after an error or disconnect, ...)
so drop stopping the connection in those cases.

ctdb_tcp_tnode_cb() is called when we receive data on the outgoing connection.
This can happen when we get an EOF on the connection because the other side as
closed. In this case data will be NULL.
It would also be called if we received data from the peer. In this case data
will not be NULL.
The latter case is a fatal error though and we already call
ctdb_tcp_stop_connection() for this case as well, which means even though the
node is not fully connected anymore, by not calling the node_dead() upcall
NODE_FLAGS_DISCONNECTED will not be set.

When "ctdb shutdown" is run with -n <N> it does not wait for the node
<N>'s ctdbd to go down but exits immediately. This means that the
local_daemons.sh shutdown command can find the PID file still present
and then attempt the shutdown, but the daemon can have exited between
the check and the shutdown. Although the test waits until the node is
disconnected, the transport is taken down just before the exit, so
this does not guarantee the daemon has exited.
A local shutdown command (no -n <N>) waits until the socket
disconnects and this happens *after* the PID file is gone, so this is
safe to use with the local_daemons.sh shutdown command.

Till now 50.samba script was based on RHEL versions <=6 where we didn't
have separate start up script for nmb and smbd used to start nmbd when
required. Now that nmbd has its own start up script named "nmb" it is
reasonable to have "nmb" as default value for CTDB_SERVICE_NMB inside

Separate functions are not needed for stopping/starting/restarting
individual nodes. The stop and start functions essentially just use
onnode, though for local daemons this is embedded in local_daemons.sh.
So, just provide one stop and one start function that takes an
optional nodespec, defaulting to all nodes.
Restarting becomes common.

If we can't bind the local end of an outgoing connection then
something has gone wrong. Retrying is better than failing into a
zombie state. The interface might come back up and/or the address my
be reconfigured.
While here, do the same thing for the other (potentially transient)
failures.
The unknown address family failure is special but just handle it via a
retry. Technically it can't happen because the node address parsing
can only return values with address family AF_INET or AF_INET6.

There is no sane way of keeping stdin open when using the shell to
background ctdbd in local_daemons.sh. Instead, have ctdbd fork when
not interactive and when test mode is enabled. become_daemon() can't
be used for this: if it forks then it also closes stdin.
For the interactive case, become_daemon() wasn't doing anything
special, so do nothing instead.
