dba248236c smartcontract: add CreateDefaultMultiSigRedeemScript 
And use it where appropriate. Some of our code was just plain wrong (like the
one in GAS contract) and unification is always useful here.

80302c5c07 consensus: use dbft.M() for new block witness 
We're collecting dbft.M() number of signatures in getBlockWitness(), so we
should use the same value for M here.

f2cb1d5f02 compiler: use constants in interops 
We now support using exported constants, so there is no
need in declaring functions. All functions from `interop/`
are not to be compiled.

d5a9d80c12 core: refactor out policy check for transaction 
We were checking blocked accounts twice which is obviously excessive. We also
have our accounts sorted, so we can rely on that in CheckPolicy(). It also
doesn't make much sense to check MaxBlockSystemFee in Blockchain code, policy
contract can handle that.

It no longer depends on blockchain state and there can't ever be an error, in
fact we can always iterate over signers, so copying these hashes doesn't make
much sense at all as well as sorting arrays in verifyTxWitnesses (witnesses
order must match signers order).

6c8accf18c core, network: request blocks instead of headers 
Closes #1192

1. We now have CMDGetBlockByIndex, so there's no need to request headers
   first when we can just ask for blocks.
2. We don't ask for headers (i.e. we don't send CMDGetHeaders),
   consequently, we shouldn't react on CMDHeaders.
3. But we still keep on reacting on CMDGetHeaders command as
   there could be a node which needs headers.

7c6cdcbcc9 core: fix bug with policy.MaxVerificationGas 
In 121c9664b we should take into account isValid flag of
NativePolicy contract while retrieving MaxVerificationGas native
policy value. Otherwise we won't be able to get MaxVerificationGas
after the node was restarted, because this value is not truly
stored along with the other native policy values.

This commit fixes bug with headers verification after the  node
restarting with an existing storage:

c16bb466a0 stackitem: implement marshaling to JSON with types 
There are 2 kinds of JSON marshaling:
1. Lossy raw marshaling, when type information is lost and
    map keys are expected to be valid utf-8 strings.
2. Almost lossless marshaling, which can handle any non-recursive item.
    Interop value preserves only type.

This commit implements the second.
