Network server constructor reads config.Version variable, and
testcli.DeployContract writes dummy config.Version which causes
race in tests. Avoid this race by moving config.Version initialisation
to a separate package and perform it inside test packages init().

RPC binding config may be malformed or the source .go contract may contain
structures like this:
```
type Str struct {
Field int
field int
}
```
We need to recognise these cases and return error. otherwise the resulting
binding can't be compiled.

It helps us to keep the index clean and ordered. When some new RPC binding

Currently we have problems with unnamed structs used as a parameter for
notifications, because there's no one-to-one correspondence between
notification parameter and the list of extended types used by the whole
contract. Otherwise eventtypes guessing works OK.

config_extended.yml contains an example of user-defined configuration
file with extended event types. User-defined event types are allowed
to be named and complicated, i.e. properly support extended types
notation.

Unfortunately, without pre-set user extended types configuration for events
and without --guess-eventtypes flag set we are allowed to rely only on manifest
information about types. Manifest can't give us a lot of information, but we
still need to be able to generate RPC binding. Arrays and structs are correctly
handled by the current code, but maps always rely on the fact that map's value
type is set. It's not true in the described case, so make the maps type convertor
handle this situation in a similar way how arrays are handled.

There are two ways of doing this: first one is to emit all notifications
parameter data into rpcbindings configuration on compile time (event if
the parameter has a simple type), and the second one is to fetch parameter
type from the manifest on rpcbinding file generation if needed (we always
have manifest at this stage, thus it's not a problem to retrieve necessary
information). The latter case is chosen to reduce the bindings configuration
file size.

Notification and its parameters may have any UTF8-compatible name
which is inappropriate for bindings configuration and for the resulting
RPC bindings file. This commit stores the prettified version of
notification's name and parameters that are ready to be used in the
resulting RPC binding without any changes.

The user should specify it via parameter's `extendedtype` field and
via upper-level `namedtypes` field of the contract configuration YAML.
Also, as we have proper event structure source, make the `--guess-eventtype`
compilation option and make event types guess optional.

If `StartWhenSynchronized` is unset in config, `node` command runs RPC
service instantly. Previously there was a ground for deadlock. Command
started RPC server synchronously. According to server implementation, it
sends all internal failures to the parameterized error channel. Deadlock
occured because main routine didn't scan the channel.
Run `rpcsrv.Server.Start` in a separate go-routine in `startServer`.
This prevents potential deadlock caused by writing into unread channel.
Fixes#2896.
