Move dissectors to epan/dissectors directory.

Also move ncp222.py, x11-fields, process-x11-fields.pl,
make-reg-dotc, and make-reg-dotc.py.

Adjust #include lines in files that include packet-*.h
files.

+ *
+ * The Wellfleet Breath of Life (BOFL) protocol is used as a line sensing
+ * protocol on:
+ *
+ * - Ethernet LANs to detect transmitter jams.
+ * - Synchronous lines running WFLT STD protocols to determine if the line
+ *   is up.
+ * - Dial backup PPP lines.
+ *
+ * The frame format of Wellfleet BOFL is shown following the Ethernet header
+ * in the following illustration:
+ *
+ *  Destination   Source    8102    PDU   Sequence   Padding
+ *       6           6        2      4       4       n bytes
