network: allow discoverer to reuse addresses
...
...and don't try to connect to the nodes we're already connected to.
Before this change we had a problem of discoverer throwing away good valid
addresses just because they are already known which lead to pool draining over
time (as address reuse was basically forbidden and getaddr may not get enough
new nodes).

network: enlarge address request queue
...
Queuing one message is not reliable enough, the peer that gets it can fail to
actually make a request, so make this queue a bit deeper to have a higher
chance of success.

network: handle errors and connection close more correctly
...
This makes writer side handle errors properly and fixes communication between
reader and writer goroutine to always correctly unregister the peer. This is
especially important for the case where error occurs before handshake
completes as in this case we don't even have goroutine in startProtocol()
running.

network: close connection on disconnect
...
If it's already closed, this won't hurt, but in the case of logical error it
saves us from leaking this connection (and potentially, peer).

storage: fix reading overlapping hash blocks from the DB
...
In the unlikely event of overlapping hash block written to the DB we might end
up with wrong hash list. That happened to me for some reason when synching
with the testnet leading to the following keys with respective values:
150000 -> 2000 hashes
152000 -> 2000 hashes
153999 -> 2000 hashes
Reading it hashes number 153999 and 154000 got the same values and the chain
couldn't sync correctly.

Same thing done in a2a8981979
