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.

`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.

5ba4f3ef08 rpc: set transaction's script for test invocation
GetScriptContainer() interop can try to get this transaction and this attempt
will lead to hash calculation with transaction serialization, but transaction
can't be successfully serialized if it doesn't have a script set, so this
makes test invocations fail.

2f6065f541 compiler, cli: introduce *.manifest.json
Add ability to generate NEO3-compatable *.manifest.json into compiler.
This file represets contract manifest and includes ABI information, so
we don't need to create separate *.abi.json file. NEO3 debugger also
needs *.manifest.json only. So, switched from *.abi.json to
*.manifest.json file.

a46c71f2de consensus: prevent synchronization stalls
When CN is not up to date with the network is synchonizes blocks first and
only then starts consensus process. But while synchronizing it receives
consensus payloads and tries to process them even though messages reader
routine is not started yet. This leads to lots of goroutines waiting to send
their messages:

Luckily it doesn't break synchronization completely as eventually connection
timers fire, the node breaks all connections, create new ones and these new
ones request blocks successfully until another consensus payload stalls them
too. In the end the node reaches synchronization, message processing loop
starts and releases all of these waiting goroutines, but it's better for us to
avoid this happening at all.

This also makes double-starting a no-op which is a nice property.
