io: move size calculator there
...
It's mostly used for Serializable and in other cases where one needs to
estimate binary-encoded size of the stucture. This also simplifies future
removal of the Size() from Serializable.

io: move BinReader/BinWriter there, redo Serializable with it
...
The logic here is that we'll have all binary encoding/decoding done via our io
package, which simplifies error handling. This functionality doesn't belong to
util, so it's moved.
This also expands BufBinWriter with Reset() method to fit the needs of core
package.

This one fixes #390 and some connected problems. After this patchset the node reconnects to some other nodes if anything goes wrong and it better senses when something goes wrong. It also fixes some block handling problems based on the testnet connection experience.

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).

Queuing one message is not reliable enough, the peer that gets it can fail to

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.

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.
