eb4ec61b8b network: register connected addr in handleVersionCmd() 
Prevent useless attempts to connect to this peer if the peer has already made
a connection to us.

9eafec0d1d network: introduce peer-to-peer message queue 
This one is designed to give more priority to direct nodes communication, that
is that their messaging would have more priority than generic broadcasts. It
should improve consensus process under TX pressure and allow to handle
pings in time (preventing disconnects).

72e4eb7172 network: fix wrong NewPing() parameters 
They have the opposite order, height first and nonce second. It was done wrong
in 4e6ed902 and never fixed since. Fixes sending wrong peer state leading to
useless getheaders messages (and disconnects when the other side is lagging
behind).

b79abd1e27 network: detect duplicate connections before handshake completes 
We can have more than one connection attempt in progress and not yet completed
the handshake, so if there is a Version already received we should look it.

b1b660c779 rpc: fix getaccountstate/getunspents for unknown addresses 
Returning error string as a result (not an error) is utterly wrong, but C#
implementation just returns a zero balance for unknown addresses, so we should
follow that.

390bf58f97 consensus: use our implementations of Recovery* messages 
While decoding payload, local implementations of Recovery*
messages were used, but when creating RecoveryMessage inside dBFT
library default NewRecoveryMessage was invoked. This lead to parsing

06c3fbe455 network: rework ping sends, fix overpinging 
Our node was too pingy because of wrong timer setups (that divided timeout
Duration by time.Second), it also was wrong in its time calculations (using
UTC time to calculate intervals). At the same time missing block is a
server-wide problem, so it's better solved with server-wide protocol loop.

2c4ace022e network/config: redesign ping timeout handling a bit 
1) Make timeout a timeout, don't do magic ping counts.
2) Drop additional timer from the main peer's protocol loop, create it
   dynamically and make it disconnect the peer.
3) Don't expose the ping counter to the outside, handle more logic inside the
   Peer.

Relates to #430.

62092c703d network: use local timestamp to decide when to ping 
We don't and we won't have synchronized clocks in the network so the only
timestamp that we can compare our local time with is the one made
ourselves. What this ping mechanism is used for is to recover from missing the
block broadcast, thus it's appropriate for it to trigger after X seconds of
the local time since the last block received.

a8252ecc05 network: remove wrong ping condition 
In reality it will never be true exactly in the case where we want this ping
mechanism to work --- when the node failed to get a block from the net. It
won't get the header either and thus its block height will be equal to header
height. The only moment when this condition is met is when the node does
initial synchronization and this synchronization works just fine without any
pings.

b5b05a969c keys: make NEP2Decrypt return a PrivateKey rather than WIF 
There is no point in encoding the output of this function in a WIF format,
most of the users actually want the real key and those who need a WIF can
easily get if from the key (and it's simpler than getting the key from the
WIF).

It also fixes a severe bug in NEP2Decrypt, base58 decoding errors were not
processed correctly.

9c79684516 storage: panic on error in boltdb.Seek 
Error in Seek means something is terribly wrong (e.g. db was not opened) and
error drop is not the right thing to do, because caller
will continue working with the wrong view.

ddad9ac9a3 hash: simplify merkle tree error handling

can remove error value return from this function and simplify NewMerkleTree().

bf84e1f2fb core: cache top block 
Turns out, our dApps use it a lot and we were going to the DB to get it which
is a useless waste of time. Technically we could also remove blockHeight here,
but not doing it at the moment as it's more involved.

It eliminates this time waste from the pprof graph, but doesn't change 1.4M ->
1.5M 100K mainnet block import test case in any noticeable way.

094c8474b7 compiler: move tests from vm/tests 
These don't belong to VM as they compile some Go code and run it in a VM. One
may call them integration tests, but I prefer to attribute them to
compiler. Moving these tests into pkg/compiler also allows to properly count
the compiler coverage they add:

-ok     github.com/CityOfZion/neo-go/pkg/compiler       (cached)        coverage: 69.7% of statements
+ok     github.com/CityOfZion/neo-go/pkg/compiler       (cached)        coverage: 84.2% of statements

This change also fixes `contant` typo and removes fake packages exposed to the
public by moving foo/bar/foobar into the testdata directory.
