aefb26255a dao: drop DAO interface 
It's a remnant from the days when we had Simple and Cached DAO
implementations, now it makes zero sense.

83d0b2f465 interop: move invocation counter from VM to Context 
It's created for interop and used by interop, VM doesn't care.

29cda5112a vm: simplify NEF loading by providing a special method 
Offsets are still handled outside of VM to avoid introducing manifest
dependency (that's likely to be circular).

It's not used and should not be used to switch from contract to contract.

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.

0b26b46234 state: store NEF instead of script for contract 
NEFs for native contracts are set statically, thus
field values are taken from the reference implementation.

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.
