commit f9739f8f57cc64d6d9025f42e5c59ecfe4635817
Author: Ken Gaillot <kgaillot@redhat.com>
Date:   Mon May 7 13:17:14 2018 -0500

Fix: libcrmservice: find absolute paths when used with "service:"
    
    Previously, "service:" would work correctly only when specified with a path
    relative to the LSB init directory. Now, it also works when the agent type is
    an absolute path.
    
    This also refactors the relevant code into new functions in services_lsb.c.
