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
[signal SIGSEGV: segmentation violation code=0x1 addr=0x28 pc=0x9d5f0a]

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.

f747b39bc6 docs: update RPC server documentation, add missing methods
And drop doc.go from server package as it duplicates docs/rpc.md and has no

server is not really expected to be used by non-neo-go packages (contrary to
the client).
