    ips: add http fast pattern buffers

    These additional fast pattern buffers are supported:

    http_raw_uri http_raw_header http_stat_code http_stat_msg http_cookie http_method

    The current implementation handles them somewhat generically, so other
    inspectors can provide a method or a stat_code buffer too.  A future
    iteration will make these buffers extensible.

    ips: minimize port group construction for any-any and bidirectional rules

    ips: enable non-service rules when service is detected

    Do fast pattern searches for port groups after service groups.

    Also, search_engine.detect_raw_tcp is applied to rules w/ or w/o a fast
    pattern (previously, erroneously, only fast-pattern rules).  In addition,
    this no longer applies to flows w/o a service inspector.  Such flows act
    as if detect_raw_tcp is true regardless of setting.
