685d44dbc1 *: support _initialize method in contracts 
Invoke `_initialize` method on every call if present.
In NEO3 there is no entrypoint and methods are invoked by offset,
thus `Main` function is no longer required.
We still have special `Main` method in tests to simplify them.

466af55dea vm: isolate stack in LoadScript 
When calling contract it must be provided with a new stack containing
only it's arguments. The result is then copied back on RET.

Fix #1220.

d2ddf7b7cb *: support invoking methods by offset 
Allow to invoke methods by offset:
1. Every invoked contract must have manifest.
2. Check arguments count on invocation.
3. Change AppCall to a regular syscall.
4. Add test suite for `System.Contract.Call`.

e87eba51f9 compiler: emit bytecode for unused exported functions

121c9664b4 core: restrict maximum gas allow for verification 
Disallow costly verification methods. We put this limit in policy
contract as it may be a subject to change in future.
In fact this value also overrides gas limit for header verification.
Close #1202.

83e53fab24 core/test: ensure public key is invalid in test 
When providing public key as a subslice, it still can be
decoded as a valid key, thus interop will not return an error
but rather push `false` on stack. This test is about providing
invalid key, so ensure this via setting invalid prefix.

797324cb04 vm: support exceptions 
Implement 3 new instructions: TRY,ENDTRY,ENDFINALLY.
1. TRY marks the start of the block where exceptions are catched.
    It has 2 arguments which are relative offsets of exception handler
    and the end of the whole try/catch construction.
2. ENDTRY denotes either end of try or catch block.
3. ENDFINALLY denotes end of finally block which is executed
    irregardless of whether an exception has occured.

8fed383523 core: adjust System.Runtime.CheckWitness interop 
Part of #1055.

It should have `AllowStates` flag.

Also removed unreachable code: we can't have such situation when
script container is not a transaction in the scope of `CheckWitness`
method because:
1. Blocks have their own implementation of CheckWitness for
internal usage (it's (bc *Blockchain) verifyHeaderWitnesses method).
2. For the outside calls of System.Runtime.CheckWitness interop (e.g.
calls from smart-contract) script container is always a transaction.
