This matches Samba4's server_id.

This will allow this structure to be shared, and allow us to create a
common messaging system between all Samba processes. Samba4 uses the
task_id to indicate the different tasks within a single unix process.

in the early CTDB days, the RELEASE_IP message was defined
and some code was added to react on such a message to make
smbd exit if the IP address it was using for the server socket
is removed by CTDB.
Later, it was discovered that we need to stop smbd immediately
and logic was added to ctdb_conn to call release_ip() without
going through the messaging system.
So this code is not used and can be removed

Volker, Tridge and other clustering gurus, please check.
It is ok to get rid of ifdef CLUSTER_SUPPORT here, right ?
Why was unique_id not marshalled at all ?

Since commit 7022554, smbds share a printcap cache (printer_list.tdb),
therefore ordering of events between smbd processes is important when
updating printcap cache information. Consider the following two process
example:
1) smbd1 receives HUP or printcap cache time expiry
2) smbd1 checks whether pcap needs refresh, it does
3) smbd1 marks pcap as refreshed
4) smbd1 forks child1 to obtain cups printer info
5) smbd2 receives HUP or printcap cache time expiry
6) smbd2 checks whether pcap needs refresh, it does not (due to step 3)
7) smbd2 reloads printer shares prior to child1 completion (stale pcap)
8) child1 completion, pcap cache (printer_list.tdb) is updated by smbd1
9) smbd1 reloads printer shares based on new pcap information
In this case both smbd1 and smbd2 are reliant on the pcap update
performed on child1 completion.
The prior commit "reload shares after pcap cache fill" ensures that
smbd1 only reloads printer shares following pcap update, however smbd2
continues to present shares based on stale pcap data.
This commit addresses the above problem by driving pcap cache and
printer share updates from the parent smbd process.
1) smbd0 (parent) receives a HUP or printcap cache time expiry
2) smbd0 forks child0 to obtain cups printer info
3) child0 completion, pcap cache (printer_list.tdb) is updated by smbd0
4) smbd0 reloads printer shares
5) smbd0 notifies child smbds of pcap update via message_send_all()
6) child smbds read fresh pcap data and reload printer shares
This architecture has the additional advantage that only a single
process (the parent smbd) requests printer information from the printcap
backend.
Use time_mono in housekeeping functions As suggested by Björn Jacke.

This is supposed to improve the winbind reconnect time after an ip address
has been moved away from a box. Any kind of HA scenario will benefit from
this, because winbindd does not have to wait for the TCP timeout to kick in
when a local IP address has been dropped and DC replies are not received
anymore.

This pidl attribute avoids the need for this dummy function, which
helps s3compat.

This is the basis to implement global locks in ctdb without depending on a
shared file system. The initial goal is to make ctdb persistent transactions
deterministic without too many timeouts.

This just does a NULL RPC call through an existing NETLOGON connection. If
someone knows an operation that "just works" and does not return NOT_SUPPORTED,
please tell me :-)
