5dc6d9207778c51c10c16fac4b3663bc7905bafc test: make BIP157 messages default-constructible (MESSAGEMAP compatibility) (Sebastian Falbesoner) 71e4cfefe765c58937b3fd3125782ca8407315d2 test: p2p: add missing BIP157 message types to MESSAGEMAP (Sebastian Falbesoner) Pull request description: The script [message-capture-parser.py](https://github.com/bitcoin/bitcoin/blob/master/contrib/message-capture/message-capture-parser.py) currently doesn't support parsing the BIP157 messages `getcfilters`, `getcfheaders` and `getcfcheckpt`, e.g. ``` $ ./contrib/message-capture/message-capture-parser.py msgs_recv.dat ... WARNING - Unrecognized message type b'getcfcheckpt' in /home/thestack/bitcoin/msgs_recv.dat ... ``` This PR fixes this by adding the missing message type mappings to the [`MESSAGEMAP`](225e5b57b2/test/functional/test_framework/p2p.py (L95-L127)) in the test framework and add default-constructors for the corresponding `msg_`... classes. Without the second commit, the following error message would occur: ``` File "/home/thestack/bitcoin/./contrib/message-capture/message-capture-parser.py", line 141, in process_file msg = MESSAGEMAP[msgtype]() TypeError: __init__() missing 2 required positional arguments: 'filter_type' and 'stop_hash' ``` ACKs for top commit: dunxen: tACK [5dc6d92](5dc6d92077) Tree-SHA512: d656c4d38a856373f01d7c293ae7d2b27378a9fc248048ebf2a64725ef8b498b3ddf4f420704abdb20d0c68ca548f1777602c5e73b66821a20c97ae618f1d63f
