Pull request description:

  This is based on https://github.com/bitcoin/bitcoin/pull/18044#discussion_r450687076.

  A new type `GenTxid` is added to protocol.h, which represents a tagged txid-or-wtxid. The tx request logic is updated to use these instead of uint256s, permitting per-announcement distinguishing of txid/wtxid (instead of assuming that everything we want to request from a wtxid peer is wtx). Then the restriction of orphan-parent requesting to non-wtxid peers is lifted.

  Also document BIP339 in doc/bips.md.

    ACK 10b7a6d532 -- code review. Using gtxid to replace the is_txid_or_wtxid flag for the mempool functions is nice.
