Forgotten testnet1 cherries (#475)

* Very quick peer banning endpoint, helps with #406
* Ping heights (#407)
* add height to ping/ping
* reformat output
* fix p2p test
* Fix orphan handling, not related to current head. Fixes #412
* Check before borrow, fixes #267
* Not finding an output commit in pos is an AlreadySpent
* Fix race condition, sending before conn is ready
* Explicit error for unknown pos of a forked block
* Remove config outdated tests. Fix #333
* Check ref and try before borrow, fix #400
* We do not want to sync with old peers anyway
* Hide cargo compiler warning for unused NoopAdapter and unused test code. Add TODOs
