changes for wait_for_getheaders to include hash_list #22312

Address #18614

Modified wait_for_getheaders to include block hash in the verification.

The following function calls of wait_for_getheaders will be changed.

• self.helper_peer.wait_for_getheaders(timeout=timeout) - (in feature_block.py)
• peer.wait_for_getheaders(timeout=5) - (in mining_basic.py)
• self.wait_for_getheaders() - (in p2p_segwit.py)
• Few more in p2p_sendheaders.py

I have only implemented how a modified version of wait_for_getheaders will look like. I had a brief overview of the get headers bitcoin coin protocol documentation. I am trying to understand terms like block locator

Are my changes the right way to approach this issue?

Closing the draft. I will send a PR with a better change later!
