Change Details

``` CNode and CConnman keep track of the active chain height when CNodes have been created, but apart from serializing the int once (when sending a version message), it is unused. So it can simply be removed in favor of a single int in PeerMan that can do the same. ``` Backport of core#20649. Depends on D10884. Ref T1696.
