Neo Legacy used migration mechanism to update contracts.
N3 provides update method in native management contract.
Therefore, it makes sense to rename `Migrate` to `Update`.

As soon as migration required changes in memory, we
need bigger scope. Otherwise in requires two step migration
which is unpleasant and annoying.

All ballots and voting methods are gone. Multi signature
checks are used in all contracts.
Default global config values are also removed. Configuration
must be provided by initialization script.
Signed-off-by: Alex Vanin <alexey@nspcc.ru>
Ballots are inefficient to collect invocations of contract methods.
Instead contract can check multi signature collected outside of the
contract, e.g. with notary service.

The only correct way to calculate threshold is
the first one.

entry point in contract. But right now there is
no point in this.

There is an issue with native contract callback functions

This should fix it for now.
