In the control request, database id which is a 32-bit integer is sent
on wire as a 64-bit integer rather than a 32-bit integer. If we
convert the database id to 64-bit integer before sending, the order of
32-bits with database id will vary depending on the endian-ness.
Instead send the database id as first 32-bits and zeros as next 32-bits.

When using non-standard test subdirectories, the current code can fail
to find the test bin directory and stupidly just adds /bin to PATH.
Switch to using CTDB_TESTS_ARE_INSTALLED along with some sanity checks
to determine the mode of operation.
With this change, test directories can now be created as
subdirectories of arbitrary component directories. Tests can then be
run directly, either by specifying the subdirectory or individual test
cases.
Integration into the top-level tests/ directory is then done via a
symbolic link, which enables 2 things:
* Ability to run a directory of test cases from top level by simply
specifying the link name.
* Ease of installation - the installation code just works with the
symbolic link.

This causes any tracked connections for the IP address to be lost.
When doing a takeip, the server sends a tickle ACK to the client, the
client responds with a valid ACK and the server's TCP stack responds
with a reset because the connection does not exist. However, in the
updateip, case the connection *does* exist, so the tickle *does not*
cause the connection to be reset.
ctdb_announce_vnn_iface() clears the list of tracked TCP connections
while sending the tickle ACKs. So, if there are no reconnects as in
the takeip case, then the list of connections is simply lost.
The "updateip" event in the 10.interface event script already sends
gratuitous ARPs and tickles connections in both directions. This
ensures that traffic continues after packets may have been dropped
when the script temporarily blocks traffic to the IP address.
All of this means that the call to ctdb_announce_vnn_iface() can just
be deleted.

Currently, every lock helper will log a message if it cannot get a lock.
This can spam the logs and overwhelm syslog if there are hundreds of
lock helpers waiting for contended record.
Instead keep track of the record for which we have already logged once
with specific timeout interval. If we get timeout interval larger than
the previously logged interval, then log again once. This will reduce
the amount of logs for contended records to a single log entry per 10
seconds per record.

When thousands of connections are being killed the logs are flooded
with information about connections that should be killed. When some
connections are not killed then the number not killed is printed.
This is the wrong way around! When debugging "fail-back" problems, it
is important to know details of connections that were *not* killed.
It is almost never important to know the full list of all connections
that were *supposed* to be killed.
Instead, print a summary showing how many connections of the total
were killed. If any were not killed then print a list of remaining
connections.
