e8d2277fe5 contract/vm: only push NULL after call in dynamic contexts
And determine the need for Null dynamically. For some reason the only dynamic
context is Contract.Call. CALLT is not dynamic and neither is a call from
native contract, go figure...

13f5fdbe8a vm: extract shared parts of the Context
Local calls reuse them, cross-contract calls create new ones. This allows to
avoid some allocations and use a little less memory.

fab8dfb9f8 vm: move State type into a package of its own
It's used a lot in other places that need it, but don't need whole VM at the
same time.

638b04b29a interop: wrap contract.LoadToken in context.LoadToken
Creating a closure in runtime is a relatively costly thing, but it can easily
be avoided.

3509523baf contract: tune isolation logic
Wrap when we have outer exception handler and the method is not
safe. Otherwise we wrap almost always, since non-readonly methods are very
common.

Offsets are still handled outside of VM to avoid introducing manifest

f9f1fe03b2 core: refactor native call
1. `System.Contract.CallNative` expects version on stack.
2. Actual method is determined based on current
   instruction pointer.
3. Native hashes don't longer depend on NEF checksum.

b7e86fa6a3 manifest: add Safe flag to method descriptor
`interop.Contex.AddMethod` sets `Safe` flag for native
contracts. This allows not to forget to change manifest
when changing call flags.
Also fixed invalid `Safe` flags for `Notary` and `Designate` contracts.

d93aa745bb contract: avoid going to the DB for entry scripts
This optimizes out DB access for non-deployed contracts under the assumption
that deployed ones are always loaded via `LoadScriptWithHash` (and if they're
not --- it's a bug anyway with the new hashing model) which actually is a very
popular case (every entry script does that).

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).

30526046e7 native: don't push void result in Call
This was done in https://github.com/neo-project/neo/pull/1693
for native calls. `OnPersist` script still uses `DROP` though
as value is pushed via `CheckReturn` logic for regular calls.
