    This is a very basic class and does not represent all possible fields
    in an avc message. Currently the fields are:
       scontext - context for the source (process) that generated the message
       tcontext - context for the target
       tclass - object class for the target (only one)
       comm - the process name
       exe - the on-disc binary
       path - the path of the target
       access - list of accesses that were allowed or denied
       denial - boolean indicating whether this was a denial (True) or granted
          (False) message.

    An example audit message generated from the audit daemon looks like (line breaks
    added):
       'type=AVC msg=audit(1155568085.407:10877): avc:  denied  { search } for

ed�ZRS(s�Parser for audit messages.

    This class parses audit messages and stores them according to their message
    type. This is not a general purpose audit message parser - it only extracts
    selinux related messages.

    Each audit messages are stored in one of four lists:
       avc_msgs - avc denial or granted messages. Messages are stored in
          AVCMessage objects.
       comput_sid_messages - invalid sid messages. Messages are stored in
          ComputSidMessage objects.
       invalid_msgs - selinux related messages that are not valid. Messages
          are stored in InvalidMessageObjects.
       policy_load_messages - policy load messages. Messages are stored in
          PolicyLoadMessage objects.

    These lists will be reset when a policy load message is seen if
    AuditParser.last_load_only is set to true. It is assumed that messages
    are fed to the parser in chronological order - time stamps are not
    parsed.
