Uncompresses a DNS compressed name.

The containing DNS message is required because of the compressed encoding and reference suffixes present elsewhere in the packet.

If the name is less than dst_len characters long, the remainder of dst is terminated with \0 characters. Otherwise, dst is not terminated.

If dst_len is 0 dst can be NULL. Returns the uncompressed name length.
