Improved navigation of /cvmfs in the Parrot-CVMFS driver.
It now shows the list of filesystems that can be configured.
Along the way, cleaned up the debug output of the driver
to be more consistent with other Parrot drivers.
Comment clarifying the use of remove_unready_workers().
Support for inode monitoring.
Added -Z port-file to catalog_server.

Monitor inotify support
Only set CCTOOLS_TEST_LOG if unset.
Add missing h and i options.
Added -R resource display functionality to work_queue_status
Only show the CVMFS multiple-repository text once, otherwise
the user is overwhelmed.
Updated the work_queue_status man page to include -R explanation.
Fold do_keepalive_check() and remove_unready_workers() into one function and
refactor their code and organization. With this change, we iterate through the
worker table only once for both functions.
