Add Murch’s inputs #208

Add inputs via set_cover_merge from upstream and active fuzzing to create new corpora then adding back the upstream inputs as usual.

It does not include p2p_headers_presync, so I presume you've excluded it manually for now to avoid hitting the timeout bug?

I probably last pulled Bitcoin Core over three weeks ago, due to working on my BIP proposal and then being on vacation. So, given the timing of #207, I would guess that I just didn’t have a version with that fuzz target yet.

git reflog says I was on 0725a374941355349bb4bc8a79dad1affb27d3b9.

Happy to merge this one, or wait longer. Just let me know what you prefer. On a quick glance it looks like the runtime is larger by 30%, so this should hopefully add some coverage.

I am adding some fuzzing for p2p_headers_presync and clusterlin_make_connected, then merging again.

Please don't add the p2p_headers_presync corpus it currently breaks the windows and macos ci.

Alright, did some light fuzzing on clusterlin_make_connected and p2p_headers_presync, threw away p2p_headers_presync, did a fresh merge with the results from last nights fuzzing, now I think it should be good to go.

Looks like there is a mild increase, but not too much:
