79eaa196dc s3:smbd: disconnect the all client connections if a ctdb public ip dropped
For now we keep it simple and any disconnect on a connection that
used a ctdb public address, will disconnect all other remaining
connections.

8b8c5c4154 s3:smbd: force multi-channel to be turned off without FreeBSD/Linux support
For now it's safer to disable multi-channel without having support
for TIOCOUTQ/FIONWRITE on tcp sockets.

Using a fixed retransmission timeout (rto) of 1 second would be ok,
but we better require kernel support for requesting for unacked bytes
in the kernel send queue.

"force:server multi channel support = yes" can be used to overwrite
the compile time restriction (mainly for testing).

3cd775af05 s3:smbd: add infrastructure to wait for TCP acks
This will be the core of the logic that allows
us to retry break notifications.

When we start the "pending break cycle" we ask for
the current retransmission timemout (rto) on the TCP connection
and remember how many unacked bytes are in the kernel's
send queue. Each time we send bytes into the kernel
we add them to the unacked bytes.
We use a timer using the rto interval in order
to check the amount of unacked bytes again.
The provides send_queu_entry.ack.req will be completed
with tevent_req_done() when everything is completely acked,
tevent_req_nterror(NT_STATUS_IO_TIMEOUT) when
send_queu_entry.ack.timeout is expired or
tevent_req_nterror(connection_error) when the connection
gets disconnected.

It works with support from the FreeBSD and Linux kernels.
For other platforms we just have a fixed rto of 1 second.
And pretend all bytes are acked when we recheck after 1 second.
So only a connection error could trigger tevent_req_nterror(),
but there's no timeout. A follow up commit will most likely
disable support for multi-channel if we don't have kernel support.

54bd3a46c8 s3:smbd: add smbd_server_disconnect_client[_ex]()
With multichannel things may not happen only on one connection.
We may need to disconnect all connections of a client, when something
bad happens.

The first users of this will be the lease/oplock break code,
if they are not able allocate memory or something similar
we need to bail out.

Having a special smbXsrv_client based function is better than
calling exit_server*() directly.

In memory of get_valid_user_struct() and functionally equivalent it only returns
the session if session setup was successfully completed and
session->global->auth_session_info is valid.

This function is similar to smbXsrv_session_local_lookup() and it's wrappers,
but it doesn't implement the state checks of those. get_valid_smbXsrv_session()
is NOT meant to be called to validate the session wire-id of incoming SMB
requests, it MUST only be used in later internal processing where the session
wire-id has already been validated.
