Also uncommented a bunch of PSBT functional tests (had to add a fee output
to one transaction, update `find_output` to skip CT outputs, and change two
constant checks at the end of the commented-out section).
fa8489a155 test: Add test for BIP30 duplicate tx (MarcoFalke)
77770d95e2 test: Properly serialize BIP34 coinbase height (MarcoFalke)
Pull request description:
This adds a test for BIP30 to check that duplicate txs can exist in the blockchain given the first one was completely spent when the second one is added. (Requested by ajtowns in https://github.com/bitcoin/bitcoin/pull/16333#issuecomment-508604071)
We can not add a test that a later duplicate tx overwrites a previous one, because BIP30 is always enforced on regtest. If someone feels strongly about such a test, some Bitcoin Core code would have to be modified, which can be done in a follow up pull request.
Also, add a commit to fix the BIP34 test failures reported in https://github.com/bitcoin/bitcoin/pull/14633#issue-227712540

Pull request description:
This is required for various work in progress:
* testchains #8994
* signet #16411
* some of my locally written tests
While it will be unused in the master branch as of now, it will make all of those pull requests shorter. Thus review for non-regtest tests can focus on the actual changes and not some test framework changes.

bead32e31e Add release notes for DEFAULT_BLOOM change (Matt Corallo)
f27309f55c Move DEFAULT_PEERBLOOMFILTERS from validation.h to net_processing.h (Matt Corallo)
5efcb77283 Disable bloom filtering by default. (Matt Corallo)
Pull request description:
BIP 37 bloom filters have been well-known to be a significant DoS
target for some time. However, in order to provide continuity for
SPV clients relying on it, the NODE_BLOOM service flag was added,
and left as a default, to ensure sufficient nodes exist with such a
flag.
NODE_BLOOM is, at this point, well-established and, as long as
there exist 0.18 nodes with default config (which I'd anticipate
will be true for many years), will be available from some peers. By
that time, the continued slowdown of BIP 37-based filtering will
likely have rendered it useless (though this is already largely the
case). Further, BIP 37 was deliberately never updated to support
witness-based filtering as newer wallets are expected to migrate to
some yet-to-be-network-exposed filters.

fa1d766717 tests: Make msg_block a witness block (MarcoFalke)
fa52eb55c9 test: Remove True argument to CBlock::serialize (MarcoFalke)
Pull request description:
Unnamed arguments are confusing as to what they mean without looking up the function signature.
Since segwit is active by default in regtest, and all blocks are serialized with witness (#15664), remove the argument `with_witness=True` from all calls to `CBlock::serialize` and `BlockTransactions::serialize`.

I also moved some RPC methods that were not at the end of the file with
the other ELEMENTS RPC methods. This makes the diff on my machine look
crazy. Let's hope GitHub has more intelligent diffs..
