634e9483d3 transaction: unmarshal Witness properly
Both verification and invocation scripts need to
be unmarshaled from hex.
Also fix failing RPC tests: block contains non-pointer
`transaction.Witness` field and (*Witness).MarshalJSON method
is not called.

81d89cd502 core: fix SystemFee calculation for Invocation TXes
They have it specified right in the transaction. Unfortunately, this little
change rendered invalid our RPC test chain, but I think it became even better
after it, especially given that chain generation is a nice test by itself, so
it should be running as a regular test.

ae6edf0601 core: add a check for fractional gas in invocation TXes
It's not allowed in C# code and that's reasonable as it's a sysfee essentially

f747b39bc6 docs: update RPC server documentation, add missing methods
And drop doc.go from server package as it duplicates docs/rpc.md and has no

server is not really expected to be used by non-neo-go packages (contrary to
the client).

b461a6ab63 compiler: do not short-circuit in complex conditions
Current implementation of short-circuting is just plain wrong
as it uses `last` or `before-last` labels which meaning depend
on context. It doesn't even handle simple assignements like
`a := x == 1 && y == 2`.

This commit makes all jumps in such conditions local
and adds tests.

Closes #699, #700.

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.

The problem is that the select in putPacketIntoQueue() only works the way it
was intended to after the `close(p.done)`, but that happens only after
successful unregistration request send. Thus, do disconnects the other way
around, first unblock queueing and exit goroutines, then destroy the
connection (if it wasn't previously destroyed) and only after that signal to
the Server.

7ee8f9c5d8 network: fix networking stalls caused by stale peers
We can leak sending goroutines and stall broadcasts because of already gone
peers that happened to be cached by some s.Peers() user (more than 800 of
these can be seen in nodoka log along with (*Server).run blocking on
CMDGetAddr send):

9b03f968b1 core: fixe FreeGasLimit constraint
Lack of FreeGasLimit in privnet leads to gas limit exceeding in case of transactions with small amount of GAS to be used for invoke operation (< real cost of the transaction). Solution: Fixed constraint in case when FreeGasLimit == 0. So now we are able to perform transactions in privnet with FreeGasLimit = 0 for free.
