This adds more serialisation to the startup, ensuring that the
"startup" event runs after everything to do with the first recovery
(including the "recovered" event).
Given that it now takes longer to get to the "startup" state, the
initscript needs to wait until ctdbd gets to "first_recovery".

If one or more run states are specified then "ctdb runstate" succeeds
only if ctdbd is in one of those run states.
At the moment, if the "setup" event fails then the initscript succeeds
but ctdbd exits almost immediately. This behaviour isn't very
friendly.
The initscript now waits until ctdbd is in "startup" or "running" run
state via the use of "ctdb runstate startup running", meaning that ctdbd
has successfully passed the "setup" event.
The "setup" event code in 00.ctdb now waits until ctdbd is in the
"setup" run state before proceeding via the use of "ctdb runstate setup".

This really needs to be per-node. The rename is because nodes with
this tunable switched on should drop IPs if they become unhealthy (or
disabled in some other way).
* Add new flag NODE_FLAGS_NOIPHOST, only used in recovery daemon.
* Enhance set_ipflags_internal() and set_ipflags() to setup
NODE_FLAGS_NOIPHOST depending on setting of NoIPHostOnAllDisabled
and/or whether nodes are disabled/inactive.
* Replace can_node_servce_ip() with functions can_node_host_ip() and
can_node_takeover_ip(). These functions are the only ones that need
to look at NODE_FLAGS_NOIPTAKEOVER and NODE_FLAGS_NOIPHOST. They
can make the decision without looking at any other flags due to
previous setup.
* Remove explicit flag checking in IP allocation functions (including
unassign_unsuitable_ips()) and just call can_node_host_ip() and
can_node_takeover_ip() as appropriate.
* Update test code to handle CTDB_SET_NoIPHostOnAllDisabled.

Samba versions 3.6.x and older do not set the database priority.
This can cause deadlock between Samba and CTDB since the locking order
of database will be different. A hack was added for automatic promotion
of priority for specific databases to avoid deadlock. This code should
not be invoked with Samba version 4.x which correctly specifies the
priority for each database.

Stops the behaviour where unhealthy nodes can host IPs when there are
no healthy nodes. Set this to 1 when an immediate complete outage is
preferred when all nodes are unhealthy. The alternative

We dont strictly need to force clients to use CTDB_FETCH_WITH_HEADER instead of CTDB_FETCH when they ask for readonly records.
Have ctdbd internally remap this internally to FETCH_WITH_HEADER and map the reply back to CTDB_FETCH_FUNC or CTDB_FETCH_WITH_HEADER_FUNC based on what the client initially asked for.
This removes the need for the client to know about the CTDB_FETCH_WITH_HEADER_FUNC function and simplifies the client code.
Clients that do not care what the header after the request is can just continue using the old CTDB_FETCH_FUNC call and ctdbd will do all the difficult stuff.

These nodes can not become natgw master since they lack external network
connectivity.
These nodes are configured just the same way as for any other node with
NATGW, with the following two exceptions :
* we do NOT set CTDB_NATGW_PUBLIC_IFACE at all on these nodes.
since these ndoes lack external network we should not check the interface
for link.
* we must set CTDB_NATGW_SLAVE_ONLY=yes to flag that this is a node that
can not become natgw master.
