databases so when we restart and begin syncing, we re-download and
push those rolled back blocks (fixes bug introduced in
a5071f2568).
Fix logging of incorrect block numbers in p2p log.
Delayed node is much like witness_node, except it doesn't have support
for block productuion (thus cannot be a witness) and it is not intended
to use the P2P network. The delayed node requires a trusted node it can
connect to via RPC and download blocks from. The delayed node will only
download blocks from the trusted node if those blocks have received a
configurable number of confirmations.
This commit effectively resolves#237
