5bda068773 dbwrap_ctdb: only fetch a read-only copy if we had a record already. 
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.

99f2177e8f s3-ctdb: Make use of CTDB_CONTROL_CHECK_SRVIDS 
This should be a lot quicker than PROCESS_EXISTS followed by looking at

0e4c358e27 tdb_compat.h: divert every tdb build and includes to tdb_compat 
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.

4c1c3f2549 s3: Implement global locks in a g_lock tdb 
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.

dc6edf1ab4 s3:cluster: fix ctdb ipv6 support 
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).

465176b7e2 s3:cluster: register the client connection via CTDB_CONTROL_TCP_ADD 
This means we correctly pass IPv6 addresses too.
(CTDB_CONTROL_TCP_CLIENT was IPv4 only)

30191d1a57 RIP BOOL. Convert BOOL -> bool. I found a few interesting 
bugs in various places whilst doing this (places that assumed
BOOL == int). I also need to fix the Samba4 pidl generation
(next checkin).

de565785f5 r23410: Merge the core of the cluster code. 
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...
