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`.

9f9db39041 QA/mininode: Send all headers upfront in send_blocks_and_test to avoid sending an unconnected one (Luke Dashjr)
Pull request description:
While this doesn't currently trigger any problems, the network protocol does expect headers to be sent connectable in normal circumstances, and if too many are sent out of order will disconnect the peer.

This adds methods to the test framework that can be called by just `self.sync_*()`.
This avoids having to import the underlying util method. Also, in the default case, where all nodes are synced this avoid having to pass `self.nodes` explicitly.
So the effective changes are:

8f5d9431a Add regtests for HTTP status codes. (Daniel Kraft)
Pull request description:
This adds explicit tests for the returned HTTP status codes to `interface_rpc.py` (for error cases) and the HTTP JSON-RPC client in general for success.
#15381 brought up discussion about the HTTP status codes in general, and the general opinion was that the current choice may not be ideal but should not be changed to preserve compatibility with existing JSON-RPC clients. Thus it makes sense to actually test the current status to ensure this desired compatibility is not broken accidentally.

fab0d85802 qa: Remove mocktime unless required (MarcoFalke)
Pull request description:
When starting a test, we are always in IBD because the timestamps on cached blocks are in the past. Usually, we solve that by generating a block at the beginning of the test.
That is clumsy and might even lead to other problems such as #15360 and https://github.com/bitcoin/bitcoin/issues/14446#issuecomment-461926598
So fix that by getting rid of mocktime and always refreshing the last block of the cache when starting the test framework.
Should fix#14446
