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`.

In v0.8.0:
- containers were stored as stable marshaled binary,
In v0.9.0:
- containers are stored the same way as eACL,
- eACL structure has new `token []byte field`.

With contract migration from v0.8.0 to v0.9.0 we need to replace
structures in contract memory. This produces native contract calls
that are not available in scope of `management.Update`. Therefore
we need to apply new scope first.

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

Container now stored the same way as ExtendedACL: with
signature and session token. This is required for signature
checks when session token presented.

Signature check may fail if container has NFT attributes.
So these checks should be done in alphabet nodes and not
inside the contract.

- burn,

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.
