commit 7d8b59139a5adeaed3f72b4e5e4749a13a77300b

    services: Export 'service-extension' procedures.
    * gnu/services.scm: Export service-extension-target and
    service-extension-compute.  This allows for greater extensiblity of services
    by enabling service extensions to be wrapped.  For example, the parameters
    passed to the compute function can be modified, or the return value of the
    compute function can be modified.
