f9f1fe03b2 core: refactor native call 
1. `System.Contract.CallNative` expects version on stack.
2. Actual method is determined based on current
   instruction pointer.
3. Native hashes don't longer depend on NEF checksum.

ac527650eb native: add Ledger contract, fix #1696 
But don't change the way we process/store transactions and blocks. Effectively
it's just an interface for smart contracts that replaces old syscalls.

Transaction definition is moved temporarily to runtime package and Block
definition is removed (till we solve #1691 properly).

43e4d3af88 oracle: integrate module in core and RPC 
1. Initialization is performed via `Blockchain` methods.
2. Native Oracle contract updates list of oracle nodes
  and in-fly requests in `PostPersist`.
3. RPC uses Oracle module directly.

2f8e7e4d33 native: fix getvalidators to match C# implementation 
ValidatorsCount is not initialized at block 0 with C# node (the first voter
initializes it) and until that initialization happens the standby validators
list is being returned as is without sorting.

Fixes state mismatch for the key ffffffff0e00000000000000000000000000000001 in
the first blocks.

It also affects tests as now the first validator is different and it receives
the network fees.

1081791c68 core: fix contract manifest unpacking in System.Contract.Create 
It's just JSON, io.Serializable is only used for DB storage where the length
should be obtained from the stream. Fixes:

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.

5fe8287fbb rpc: use non-pointer Block and Transaction in results 
Pointers can be nil and in some cases it's important to always have access to
Block or Transaction fields.

7b4ca57e33 *: change address to the new format 
NEO3 uses new prefix for address (53 = 0x35), thus string representations as
well as encrypted WIFs should be changed.
