[Pki-devel] [Patch] Alternative CLI password methods (revised 20140807)

Please review the attached patch (revised) which implements alternative CLI password methods to address the following PKI TRAC ticket: * PKI TRAC Ticket #555 - Other ways to specify CLI password <https://fedorahosted.org/pki/ticket/555> This revised patch attempts to address most of the comments to the previous patch including: * made numerous man page changes * camelCased method names * changed the password routine to utilize the '=' delimiter rather than the ':' delimiter (more appropriate for Java) * consolidated the two password file routines into a single routine which supports 'token=password' format (as well as documenting and providing man page examples for how to utilize this style of file with a simple password) * removed all warning messages from the password routine * utilized suggestions to improve the password routine including replacing the use of the StringUtils.split() method with the String.split() method using a regex * rewrote password routine to handle passwords that contained the delimiter as a part of the password * ditched 'DRM' * removed consolidated error messages and exited immediately * removed the '-y' option * moved password prompting under the control of the pki CLI program for both basic and client authentication * removed previous changes to URI/URL * removed previous changes to subsystem type * added mutual exclusive test for "-n" (client authentication) vs. "-u" (basic authentication) options * added mutual dependency tests as needed
