From: Martin Wilck <mwilck@xxxxxxxx>
Split libmultipath into two libraries: libmpathutil contains
generic utilities that don't relate to device-mapper or multipath
specifically. libmultipath retains multipath-specific code.
The reason for this change is that we'll create a small client program
that takes over the role of "multipath -k", the interactive client.
This way multipathd doesn't need to link against libreadline any more.
The client only needs functionality from libmpathutil, which doesn't
contain code that isn't compliant with GPL-3.0, and can thus be linked
to libreadline without conflicts.
The new library contains weak implementations of {get,put}_multipath_config,
which are meant to be superseded by libmultipath's implementation.
In the interactive client, these functions aren't needed.
As we now have an ABI between libmpathutil and libmultipath, the ABI
must be extended by adding functions from libmpathutil that are used
internally by libmultipath.

+ * - externally visible data structures changed in incompatible ways
+ * (like offsets of previously existing struct members)
+ * In this case, the new version doesn't inherit the previous versions,
+ * because the new library doesn't provide the full previous ABI any more.
+ * All predecessors are merged into the new version.
+ *
+ * * Bump $MINOR for compatible changes, like adding symbols.
