[Yum] some refactoring...

[Vladimir Bormotov]

                Hi!

 now clientStuff.take_action() looks:
  
============== cut =========== 
 def take_action(cmds, nulist, uplist, newlist, obslist, tsInfo,
                 HeaderInfo, rpmDBInfo, obsdict):
    from yummain import usage

    _command = cmds.pop(0)

    if (conf.uid != 0) and \
       (_command in ['install', 'update', 'clean', 'upgrade', 'erase']):
      errorlog(0, _('You need to be root to perform these commands'))
      sys.exit(1)

    if _command == 'install':
        action_install(cmds, nulist, tsInfo, HeaderInfo, rpmDBInfo)
    elif _command == 'provides':
        action_provides(cmds, nulist, HeaderInfo, rpmDBInfo)
        sys.exit(0)
    elif _command == 'update':
        action_update(cmds, nulist, uplist, newlist, obslist, tsInfo,
                      HeaderInfo, rpmDBInfo)
    elif _command == 'upgrade':
        action_upgrade(cmds, nulist, uplist, obslist, tsInfo, HeaderInfo,
                       rpmDBInfo, obsdict)
    elif _command in ['erase', 'remove']:
        action_erase(cmds, tsInfo, rpmDBInfo)
    elif _command == 'list':
        action_list(cmds, nulist, uplist, newlist, HeaderInfo, rpmDBInfo)
        sys.exit(0)
    elif _command == 'info':
        action_info(cmds, nulist, uplist, newlist, HeaderInfo, rpmDBInfo)
        sys.exit(0)
    elif _command == 'clean':
        action_clean(cmds, HeaderInfo, rpmDBInfo)
        sys.exit(0)
    else:
        usage()
============== cut =========== 

 1. I just "extract" each action into separate function, named action_*
 2. List object can pop element, as result we pop command from cmds, once.
 
  each case modified like this:
  
    -    elif cmds[0] == 'info':
    -        cmds.remove(cmds[0])
    +    elif _command == 'info':
  
 I think, result very pretty ;)
