The inter-node message format belongs into messages_ctdb, not into the
generic ctdb connection layer

If it returns true the passed ip address matched and we
let a nested ctdb operation fail with NT_STATUS_ADDRESS_CLOSED.

This will avoid panic calls when smbd and winbind is started in cluster
mode before ctdb is functional. It still logs something sane at debug
level 0, but it does not panic and core anymore.

Because revoking read-only copies of records is expensive, we only
want ctdbd to do it for high-turnover records. A basic heuristic is
that if we don't find a local copy of the record, don't ask for a
read-only copy.
The fetch itself will cause ctdbd to migrate the record, so eventually
we will have a local copy. Next time it gets migrated away, we'll
call ctdbd_fetch() with local_copy = true.

This should be a lot quicker than PROCESS_EXISTS followed by looking at
serverid.tdb

We change all the headers and wscript files to use tdb_compat; this
means we have one place to decide whether to use TDB1 or TDB2.

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.
We need to use CTDB_CONTROL_TCP_CLIENT instead of CTDB_CONTROL_TCP_ADD.
CTDB_CONTROL_TCP_CLIENT has support for 2 modes in newer ctdb versions:
- with struct ctdb_control_tcp it only supports ipv4.
- with struct ctdb_control_tcp_addr it supports ipv4 and ipv6.
You need new header files which defines struct ctdb_control_tcp_addr,
but at runtime it should be fine to work against older
ctdb versions (<= 1.0.68).

bugs in various places whilst doing this (places that assumed
BOOL == int). I also need to fix the Samba4 pidl generation
(next checkin).

I'm 100% certain I've forgotten to merge something, but the main code
should be in. It's mainly in dbwrap_ctdb.c, ctdbd_conn.c and
messages_ctdbd.c.
There should be no changes to the non-cluster case, it does survive make
test on my laptop.
It survives some very basic tests with ctdbd enables, I did not do the
full test suite for clusters yet.
Phew...
