While doing this:
* Explicitly assign RPC program and version information in
_nfs_check_rpc_common(). This is more lines of code but is easier
to read.
* Don't print the options when starting a service. Trying to print it
makes the code messy for little benefit.
Update the eventscript unit testing code and a Ganesha test to
reflect this.

That is, output that goes through background_with_logging() just gets
"&" prepended to each line. This is cleaner than having the tests
grovel through logs.

Update the missing IP test to wait until restarts are complete.
Otherwise a service restart can collide with the following monitor
event and cause chaos.
Also, do not disable 10.interface until it matters. Disabling it too
early can cause even more chaos if something goes wrong with the
monitor step.

When creating missing databases either locally or remotely, recovery
master calls ctdb_ctrl_createdb(). Recovery master always passes 0
for tdb_flags. For volatile databases, if TDB_INCOMPATIBLE_HASH is not
specified, then they will be attached without using jenkins hash causing
database corruption.

Currently queue buffer size is realloc'd every time we need to extend the
buffer. Small increments can cause memory fragmentation. Instead always
extend buffer in multiples of 4K. This should reduce multiple talloc_realloc
calls when there are lots of packets in the socket buffer.
Also, if queue buffer has grown larger than 64K, throw away the buffer once
all the requests in the queue have been processed. That way queue does not
hold on to large buffers.

If there are multiple lock helper processes waiting for the same record, then
it will cause a thundering herd when that record has been unlocked. So avoid
scheduling lock contexts for the same record. This will also mean that
multiple requests will get queued up behind the same lock context and can be
processed quickly once the lock has been obtained.

This avoids issuing multiple "ctdb killtcp" commands to terminate tcp
connections, one per connection. This will considerably reduce the
time when there is a large number of tcp connections. This also makes
it possible to avoid calling "ctdb killtcp" when there are no connections.

test infrastructure to support.

The timeout information printed by ctdbd is less than useful because
it refers to the cumulative time taken by the eventscripts run so far.
Adding scriptstatus output indicates where time was actually spent.
Since there is now quite a bit of output, serialise the calls to this

A missing interface is at least as bad as an interface with a link
that is down so should have a similar effect.
This couldn't be done previously because orphaned interfaces used to
be listed for monitoring. This was worked around in 10.interface in
commit 49b2d1bd9554461ed8edbfc21e777c0eca9e1443 and fixed in ctdbd in
commit cc1a3ae911d3fee8b87fda5de5ab6d9499d7510a.
If $CTDB_PARTIALLY_ONLINE_INTERFACES="yes" then monitoring won't
actually fail but the interface is still marked as down.
While we're touching this code, use "ip link" instead of "ip addr".
It is marginally cheaper but not enough for a separate patch. ;-)
