31948ee4a7 network: add a nil check in (*TCPTransport).Close, prevent panic 
You have to try to trigger that, but in the event of server shutdown before it
actually started listening Close will easily panic like this:

2020-03-05T11:48:08.660+0300    INFO    node started    {"blockHeight": 6458, "headerHeight": 15605}
panic: runtime error: invalid memory address or nil pointer dereference

a9783d05f5 cli: implement wallet multisig sign command 
Implement ability to sign transactions with multisig address.
This should be done in several steps:
1. Create TX with `wallet transfer --out <file>`
2. Sign TX with `wallet multisign sign --in <file> --out <file2>`.
3. Repeat 2 for every party.
Input file contains transaction with possibly incomplete
set of the signatures. Output file will contain the same tx
with updated signature set.
When --rpc flag is provided, result transaction is sent
via `sendrawtransaction`.

it is useful to export tx into a file, so that
other participants can sign it too.

81d89cd502 core: fix SystemFee calculation for Invocation TXes 
They have it specified right in the transaction. Unfortunately, this little
change rendered invalid our RPC test chain, but I think it became even better
after it, especially given that chain generation is a nice test by itself, so
it should be running as a regular test.
