If port is dynamically allocated, `(*Server).Addr` will contain
0 port. This commit executes listener before exiting from `Start()`
and sets Addr to the actual address.
We're at the point where even this code can clearly be seen in profiles. We
can save on some buffers (and CPU cycles) by encoding the answer once.
Another ~2% TPS for single node.
It's not needed any more with Go 1.13 as we have wrapping/unwrapping in base
packages. All errors.Wrap calls are replaced with fmt.Errorf, some strings are
improved along the way.
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.
Implement (*Param).GetBoolean() for converting parameter to bool value.
It is used for verbosity flag and is false iff it is either zero number
or empty sting.
This error message makes no sense when shutting down the server:
2020-06-25T19:29:53.251+0300 ERROR failed to start RPC server {"error": "http: Server closed"}
And ListenAndServer is documented to always return non-nil error one of which
is http.ErrServerClosed. This should also fix the following test failure:

==================
We make it explicit in the appropriate Block/Transaction structures, not via a
singleton as C# node does. I think this approach has a bit more potential and
allows better packages reuse for different purposes.
