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:: InputAscii::empty_field
+
+   :Type: :bro:type:`string`
+   :Attributes: :bro:attr:`&redef`
+   :Default: ``"(empty)"``
+
+   String to use for empty fields.
+
+.. bro:id:: InputAscii::fail_on_file_problem
+
+   :Type: :bro:type:`bool`
+   :Attributes: :bro:attr:`&redef`
+   :Default: ``F``
+
+   Fail on file read problems. If set to true, the ascii
+   input reader will fail when encountering any problems
+   while reading a file different from invalid lines.
+   Examples of such problems are permission problems, or
+   missing files.
+   When set to false, these problems will be ignored. This
+   has an especially big effect for the REREAD mode, which will
+   seamlessly recover from read errors when a file is
+   only temporarily inaccessible. For MANUAL or STREAM files,
+   errors will most likely still be fatal since no automatic
+   re-reading of the file is attempted.
+   Individual readers can use a different value using
+   the $config table.
+   fail_on_file_problem = T was the default behavior
+   until Bro 2.6.
+
+.. bro:id:: InputAscii::fail_on_invalid_lines
+
+   :Type: :bro:type:`bool`
+   :Attributes: :bro:attr:`&redef`
+   :Default: ``F``
+
+   Fail on invalid lines. If set to false, the ascii
+   input reader will jump over invalid lines, reporting
+   warnings in reporter.log. If set to true, errors in
+   input lines will be handled as fatal errors for the
+   reader thread; reading will abort immediately and
+   an error will be logged to reporter.log.
+   Individual readers can use a different value using
+   the $config table.
+   fail_on_invalid_lines = T was the default behavior
+   until Bro 2.6.
+
+.. bro:id:: InputAscii::separator
+
+   :Type: :bro:type:`string`
+   :Attributes: :bro:attr:`&redef`
+   :Default: ``"\x09"``
+
+   Separator between fields.
+   Please note that the separator has to be exactly one character long.
+
+.. bro:id:: InputAscii::set_separator
+
+   :Type: :bro:type:`string`
+   :Attributes: :bro:attr:`&redef`
+   :Default: ``","``
+
+   Separator between set and vector elements.
+   Please note that the separator has to be exactly one character long.
+
+.. bro:id:: InputAscii::unset_field
+
+   :Type: :bro:type:`string`
+   :Attributes: :bro:attr:`&redef`
+   :Default: ``"-"``
+
+   String to use for an unset &optional field.
