Log:
  Allow cap_rights_{set,clear,is_set} to be called with no arguments.
  
  In the CloudABI code I sometimes call into cap_rights_* without
  providing any arguments. Though one could argue that this doesn't make
  sense, in this specific case it's hard to avoid, as the rights that
  should be tested against are forwarded by a couple of wrapper macros.
