Merge #11113: [net] Ignore getheaders requests for very old side blocks
eff4bd8 [test] P2P functional test for certain fingerprinting protections (Jim Posen)
a2be3b6 [net] Ignore getheaders requests for very old side blocks (Jim Posen)
Pull request description:
Sending a getheaders message with an empty locator and a stop hash is a request for a single header by hash. The node will respond with headers for blocks not in the main chain as well as those in the main chain. To avoid fingerprinting, the node should, however, ignore requests for headers on side branches that are too old. This replicates the logic that currently exists for `getdata` requests for blocks.
