When using contracts as a dependency, out-of-range `int` can cause
problems on 32-bit architectures. Contract byte-code hasn't changed.

Only leave `IRNode` in neofs contract because it is public.
The newly added conversion in `AlphabetList` shouldn't be a problem
because this is a read method.

Contract owner entity does exist anymore. Contract migration
now managed by side chain committee which are Alphabet nodes of
the Inner Ring.

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.

There is a number of contracts which return only `true` value.
Also handling `FAULT` on the client is easier then also checking return
value.

Everything can be implemented in `OnNEP17Payment` directly.
In case of 0 amount, exception is raised instead of returning `false`
value.

Processing contracts pays for cheque that transfer
assets back to the user, so user should transfer
some fee to this contract.
Withdraw fee defined in NeoFS global configuration.

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.

`x*2/3` is not equal to `x/3*2` with integers.
The only correct way to calculate threshold is
the first one.

Delete initializing of R/W context in `init()`
and start using readonly storage context in
methods where it is possible.

Change []byte type to interop.*aliasName*
types in contracts where it is suitable to
improve the readability of the contracts.

This check was useful when there was a single
entry point in contract. But right now there is
no point in this.
