Remove broxygen Sphinx integration

The broxygen-generated files now live in the git repo, have tests
that check that they are up-to-date, and a script to re-generate
them on-demand.

+================================================
+.. bro:namespace:: DPD
+
+This script enables logging of packet segment data when a protocol
+parsing violation is encountered.  The amount of data from the
+packet logged is set by the :bro:see:`DPD::packet_segment_size` variable.
+A caveat to logging packet data is that in some cases, the packet may
+not be the packet that actually caused the protocol violation.
