dns/dnsmessage: allocation free DNS message parsing and building

Parsing and building can now be done 100% allocation free for most
types. Non-name variable-length fields such as TXT records still
require allocations. Building with compression still causes allocations
due to the use of a map. Both parsing and building will perform
allocations in error paths.

Updates golang/go#16218
