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:id:: skip_http_entity_data
+
+   :Type: :bro:type:`function` (c: :bro:type:`connection`, is_orig: :bro:type:`bool`) : :bro:type:`any`
+
+   Skips the data of the HTTP entity.
+   
+
+   :c: The HTTP connection.
+   
+
+   :is_orig: If true, the client data is skipped, and the server data otherwise.

+
+.. bro:id:: unescape_URI
+
+   :Type: :bro:type:`function` (URI: :bro:type:`string`) : :bro:type:`string`
+
+   Unescapes all characters in a URI (decode every ``%xx`` group).
+   
+
+   :URI: The URI to unescape.
+   
+
+   :returns: The unescaped URI with all ``%xx`` groups decoded.
+   
+   .. note::
+   
+        Unescaping reserved characters may cause loss of information.
+        :rfc:`2396`: A URI is always in an "escaped" form, since escaping or
+        unescaping a completed URI might change its semantics.  Normally, the
+        only time escape encodings can safely be made is when the URI is
+        being created from its component parts.
