In python 3.12, "in" for enums tests values as well, so something like "12345 in dns.rdatatype.RdataType" will now return True. This broke some logic guarding against registering a known-but-unimplmemented type code point with a class that didn't have the right name. We now just give up on this test as it will never be a real problem. We change a few related tests to be more sensible.
The NSEC3 next name field is defined as base32 with no padding, but the code was doing base32 decoding with padding. This wouldn't have any effect in the normal case, since the only defined NSEC3 hashing algorithm is SHA1, and that generates a 160 bit hash that doesn't require padding when encoded in base32. This change removes generated padding after encode, rejects padded input on decode, and adds necessary padding for decode.
* Add basic DDR support.
Also removes some lint about "section = section" being a no-op.
* IntEnum improvements. This changes make() to always return an instance of the subclass, creating one on the fly if the value is not known, and updates the typ registration code to deal with this. It also adds typing annotations to make(). * Add missing int check. Some older versions of python weren't rejecting non-int values. * Fix int check. Raise TypeError for non-int, not ValueError, to make tests happy. * Annotate to_text/from_text. * Remove many the_ prefixed variables. These were needed in the past to work around typing issues.
* Improve get_rrset/find_rrset API. This allows most of the parameters to be specified as strings, matching the interface for dns.message.make_query(). * Remove unneeded "the_section". There's no need to use a separate internal variable for the section; mypy doesn't complain about reuse.
