/* Extending the Ceph Dissector.
 *
 * Hello, this is a quick overview of the insertion points in the Ceph dissector
 * it is assumed that you know how dissectors work in general (if not please
 * read 'doc/README.dissector' and related documents).
 *
 * If you have any questions feel free to contact Kevin <kevincox@kevincox.ca>.
 *
 * ## Adding a MSGR Tag
 *
 * To add a MSGR tag you must update the switch statements inside both
 * `c_dissect_msgr()` to actually dissect the data and `c_pdu_end()` to
 * calculate the length of the data.
 *
 * ## Adding a New Message.
 *
 * To add a new message type you simply create a new function
 * `c_dissect_msg_{name}()` with the same signature as the others.  Please
 * insert your function in order of the tag value like the others.
 *
 * Then you simply add it into the switch in `c_dissect_msg()` (also in the
 * correct order).  Your message will then be dissected when encountered.
 *
 * ## Supporting new encodings.
 *
 * ### Message Encodings.
 *
 * The encoding version of messages is available in `data->head.ver` and the
 * code should be modified to conditionally decode the new version of the
 * message.
 *
 * ### Data Type Encodings.
 *
 * Data types encoded using Ceph's `ENCODE_START()` macro can be decoded by
 * using `c_dissect_encoded()` to extract the version and length.  You can
 * then conditionally decode using the version.
 *
 * Please rely on the length returned by `c_dissect_encoded()` to ensure future
 * compatibility.

      Worst case is the message contains a byte that we think is a
      message.  In this case we will interpret garbage from there
      creating bogus items in the dissection results.  After we
