e12ed08bd5 ctdb: Centralize ctdb_version_string
Whenever the current git hash changes, we recompile ctdb.c and
ctdb_daemon.c. As both have quite a few warnings with -Wall, this
makes it quite difficult to see the real warnings that pop up during
development. Centralize the ctdb_version_string to just a single file
without warnings.

dcc1eaf542 ctdb-common: Add sock_client abstraction
This sets up boilerplate required for a client code connecting to a

9a9e3423d8 waf: disable-python - fix ctdb configuration
When ctdb is built in standalone mode, it turned off the python
requirement for submodules by setting Options.options.disable_python
to True before checking for its own (non-optional) python support.

Ad ctdb does not need python for itself or any of the submodules
it is built against, the safest solution seems to be to allow
the python and python-headers checks to not find python.

One change in behaviour is to actually copy the known IPs per node
instead of just assigning the pointer.  When this is used by
fake_ctdbd the resulting structure will be used to keep state for
individual nodes, so data for nodes needs to be independent.

Also, drop some asserts in the factored code and do (slightly) better
error handling.
