This is part of the progressive clean up.

The first step was to create new standalone abstractions that helped
implement parallel database recovery.  Next step was to clean up the
includes to avoid unnecessary cross-dependencies between all parts of ctdb
client/server code.

Eventually I want to replace the old client code with new client API
wherever possible. This includes ctdb tool and all of the test binaries.
We cannot get rid of the older client code completely just yet since it is
very much used in the child processes created by ctdb daemon (including
recovery daemon).  That will go away only when we separate various
daemons.  As you would have noticed Martin is working on separating cluster
operations and IP allocation from recovery daemon.

To be able to re-implement ctdb tool using new client API, I need to be
re-use some of the existing code defined in ctdb-system subsystem.  This
set of patches will help to get rid of more inter-dependencies between
various (build) subsystems and make them standalone.  I have already
re-implemented ctdb tool using new client API and working on getting tests
to work with the new tool.
