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).

2ec1d76320 compiler: add ability to generate .abi.json file
A part of integration with NEO Blockchain Toolkit (see #902). To be
able to deploy smart-contract compiled with neo-go compiler via NEO
Express, we have to generate additional .abi.json file. This file
contains the following information:
 - hash of the compiled contract
 - smart-contract metadata (title, description, version, author,
email, has-storage, has-dynamic-invoke, is-payable)
 - smart-contract entry point
 - functions
 - events

However, this .abi.json file is slightly different from the one,
described in manifest.go, so we have to add auxilaury stractures for
json marshalling. The .abi.json format used by NEO-Express is described
[here](https://github.com/neo-project/neo-devpack-dotnet/blob/master/src/Neo.Compiler.MSIL/FuncExport.cs#L66).

25da5a30d8 cli: change deploy and invoke commands to use wallet
Passing WIF directly in the command line is not something we should be doing.

Also split netfee and sysfee in the RPC as they're different (and add a script
attribute for free transactions).

bbd802681e cli: make gas parameter to deployment add gas to the base price
That's how it was intended to behave originally. One thing questionable here
is contract price (policy thing, basically) being moved to smartcontract
package, but it's probably fine for NEO 2.0 (as it won't change) and we'll
make something better for NEO 3.0.

8d73276393 cli: do not allow default value for an empty address
Right now a bizarre error message can occur if an address flag was not
set: `wallet contains no account for 'AFmseVrdL9f9oyCzZefL9tG6UbvhPbdYzM'`.
This bug is 10x worse if it occures in `transfer` --from flag.

a9783d05f5 cli: implement wallet multisig sign command
Implement ability to sign transactions with multisig address.
This should be done in several steps:
1. Create TX with `wallet transfer --out <file>`
2. Sign TX with `wallet multisign sign --in <file> --out <file2>`.
3. Repeat 2 for every party.
Input file contains transaction with possibly incomplete
set of the signatures. Output file will contain the same tx
with updated signature set.
When --rpc flag is provided, result transaction is sent
via `sendrawtransaction`.

648e0bb242 rpc/smartcontract: merge contract parameter types
Merged two types:
	- smartcontract.ParamType
	- rpc.StackParamType
into single one:
	- smartcontract.ParamType
as they duplicated the functionality.

NOTE: type smartcontract.MapType was added (as in C# implementation).

From now, list of supported smartcontract parameter types:
	UnknownType
	SignatureType
	BoolType
	IntegerType
	Hash160Type
	Hash256Type
	ByteArrayType
	PublicKeyType
	StringType
	ArrayType

b706130175 cli/server: redo dumper to dump blocks from 0
NGD dumps are all zero-based and even though I don't like it (genesys block
should not be imported, it's the root of chain trust), we have to conform to
this convention for interoperability with C# nodes (otherwise they're not able
to import our dumps).

This also renames `skip` dumper parameter to `start` which is more logical
now, the default is to start the dump from block number zero.
