b483c38593 block/transaction: add network magic into the hash
We make it explicit in the appropriate Block/Transaction structures, not via a
singleton as C# node does. I think this approach has a bit more potential and
allows better packages reuse for different purposes.

b7d2b659b4 network: get blocks directly from the chain for rebroadcasting
Simplify network<->consensus relations, also broadcast blocks received by
other means like RPC.

462022bbdd consensus: remove OnNewBlock(), use Blockchain subscription
Get new blocks directly from the Blockchain. It may lead to some duplications
(as we'll also receive our own blocks), but at the same time it's more
correct, because technically we can also get blocks via other means besides
network server like RPC (submitblock call). And it simplifies network server
at the same time.

45b8bdb51c core: fix bug in consensus
We should set MerkleRoot in approving block irrespective to

We have to set ConsensusData.PrimaryIndex field of Block, so this value
can be retrieved from consensus context.

2. Change validation rule for block: block without transactions is
valid.

65503aa9b4 core: add nonce field to transaction
1. Closes #840: added Nonce field to transaction.Transaction and
removed Nonce field from transaction.MinerTx

2. Added following methods to different tx types:
  - NewMinerTx()
  - NewMinerTxWithNonce(...)
  - NewEnrollmentTx(...)
  - NewIssueTx()
  - NewPublishTx(...)
  - NewRegisterTx(...)
  - NewStateTx(...)
in order to avoid code duplication when new transaction is created.

3. Commented out test cases where binary transaction/block are used.
These test cases marked with `TODO NEO3.0: Update binary` and need to be
updated.

4. Updated other tests

5. Added constant Nonce to GoveringTockenTx, UtilityTokenTx and genesis
block to avoid data variability. Also marked with TODO.

a903147b60 keys: rename Signature to GetScriptHash, make it return Uint160
Signature itself wasn't used at all and its name is very misleading, Uint160
script hash is way more useful.

eb11e5fb11 core: implement basic policying support, fix #370
Implement mempool and consensus block creation policies, almost the same as
SimplePolicy plugin for C# node provides with two caveats:
 * HighPriorityTxType is not configured and hardcoded to ClaimType
 * BlockedAccounts are not supported

Other than that it allows us to run successfuly as testnet CN, previously our
proposals were rejected because we were proposing blocks with oversized
transactions (that are rejected by PoolTx() now).

Mainnet and testnet configuration files are updated accordingly, but privnet
is left as is with no limits.

Configuration is currently attached to the Blockchain and so is the code that
does policying, it may be moved somewhere in the future, but it works for
now.

22f5667530 mempool: return fee along with tx when requesting tx

b9b77ac1be network: fix block relaying, don't spit out useless errors
We can only add one block of the given height and we have two competing
goroutines to do that --- consensus and block queue. Whomever adds the block
first shouldn't trigger an error in another one.

Fix block relaying for blocks added via the block queue also, previously one
consensus-generated blocks were broadcasted.

9ceefe17e2 consensus: check current chain height before processing timer
The chain may already be more current than our dBFT state (like when the node
has commited something at view 0, but all the other nodes changed view and
accepted something at view 1), so in this case we should reinit dBFT on new
height.

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
errors.

3d704a3a3a consensus: try to use previous proposal after ChangeView
When system and network pressure is high it can be beneficial
to use transactions which and were already proposed.
The assumption is that they will be in other node's memory pool
with more probability.

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.

7e371588a7 core/tx: remove one layer of indirection for scripts and inouts
It reduces heap pressure a little for these elements as we don't have to
allocate/free them individually. And they're directly tied to transactions or
block, not being shared or anything like that, so it makes little sense for
them to be pointer-based. It only makes building transactions a little easier,
but that's obviously a minor usecase.

8d4dd2d2e1 vm: move opcodes into their own package
This allows easier reuse of opcodes and in some cases allows to eliminate
dependencies on the whole vm package, like in compiler that only needs opcodes
and doesn't care about VM for any other purpose.

And yes, they're opcodes because an instruction is a whole thing with
operands, that's what context.Next() returns.
