libafscp: a library for "clientless" operations

libafscp provides the ability to accomplish many of the functions of an AFS
client without a running afsd cache manager.  It is being introduced into
the OpenAFS source tree in order to improve the capabilities of several
utilities but may have additional benefits for testing clients and servers
and for use on platforms which do not have afsd support.
