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.

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.
