This PR refactors the existing support for OPT options. It does the
following things:
o Changes all option data types to ensure their wire format is at most
65,535 octets long. This requires changing the signatures of some
creator functions. Their naming scheme and signatures are also changed
to follow the pattern established with record data.
o Renamed `UnknownOptData::from_octets` to `new` and return a result.
o Completely redesigns DNS cookie options, adding support for standard
server cookies introduced in RFC 9018.
o Change the type of `ExtendedError`’s text to `Str<Octs>` and change the
return type of `set_text` to `()`.
o Changed the type `TcpKeepalive`’s content to a newtype `IdleTimeout` to
make it easier to convert to and from durations.
o Changes Padding to just contain the padding octets and drop
`PaddingMode`. Instead, the methods on OptBuilder` should be used to
add padding.
This is a breaking change.
