fe1f0a7245 core: introduce CheckReturnState constants
At the moment we should have 3 possible options to check return state
during vm context unloading:
	* no check
	* ensure the stack is empty
	* ensure the stack is not empty

It is necessary to distinguish them because new _deploy method shouldn't
left anything on stack. Example: if we use _deploy method before some
ordinary contract method which returns one value. Without these changes
the contract invocation will fail due to 2 elements on stack left after
invocation (the first `null` element is from _deploy, the second element
is return-value from the ordinary contract method).

ae9658a108 dao: migrate nep5 balances with the contract
Fixes #1144. It's quite simple approach, we just update balance info right
upon contract migration. It will slow down migration transactions, but it
takes about 1-2 seconds to Seek through balances at mainnet's 3.8M, so the
approach should still work good enough. The other idea was to make lazy
updates (maintaining contract migration map), but it's more complicated to
implement (and implies that a balance get might also do a write).

There also is a concern about memory usage, it can give a spike of some tens
of megabytes, but that also is considered to be acceptable.

842feb2533 core: adjust System.Contract.Update interop
Part of #1055.

We should check contract scripthash against the one provided in manifest
and manifest groups. We shouldn't put on stack anything after return.
And ofcourse, we mast not destroy the old contract at the end, as
`contractDestroy` removes all storage items associated with the
old contract ID (which equals to the new contract ID). We just remove
old contract state - it's enough.
