merge-script 6f6b2bbde2 Merge bitcoin/bitcoin#35808: fuzz: reset connman state in p2p targets 
d29b22d078 fuzz: reset connman state in p2p targets (Hao Xu)

Pull request description:

  Resets `ConnmanTestMsg` at the start of each input in `cmpctblock` and `p2p_handshake`, matching the other reused-connman fuzz targets and preventing sticky `CConnman` state from leaking between corpus inputs.

  Before this, deterministic-fuzz-coverage showed single inputs were stable, but all-input directory runs were not:

  ```diff
  cmpctblock, src/net.cpp:4172
  - Branch (4172:9): [True: 1.21k, False: 33.0k]
  + Branch (4172:9): [True: 613, False: 33.6k]
  - Branch (4172:72): [True: 901, False: 311]
  + Branch (4172:72): [True: 497, False: 116]
  ```

  ```diff
  p2p_handshake, src/net.cpp:4172
  - Branch (4172:9): [True: 98, False: 1.67k]
  + Branch (4172:9): [True: 743, False: 1.03k]
  - Branch (4172:72): [True: 90, False: 8]
  + Branch (4172:72): [True: 612, False: 131]
  ```

  With the resets, `deterministic-fuzz-coverage` passed for both `cmpctblock` and `p2p_handshake`.
