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.
Without this commit the following panic occurs on attempt to generate RPC binding:

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.

New rule for writing blocks of code to our template: new line before
the block starts and new line after the block ends. This rule is the
same as the one we use during manual typing.

It's enough to specify the input file only to get the standard output:
```
$ neo-go contract compile -i ./1-print/1-print.go
$ neo-go contract compile -i ./1-print/
```

Everywhere including examples, external interop APIs, bindings generators
code and in other valuable places. A couple of `interface{}` usages are
intentionally left in the CHANGELOG.md, documentation and tests.
* strip NEP-XX methods before going into generator to avoid unused imports
* nepXX.Invoker types already include Call
* always import util, it's used for Hash
Share parameters parsing code between 'contract invokefunction' and
'vm run' commands. It allows VM CLI to parse more complicated parameter
types including arrays and file-backed bytestrings.

Still a nice thing to have.
Saving into a file can't be successful without signAndPush flag (wallet
present). This situation can't happen in CLI invocations since
testinvokefunction doesn't have `--out` flag, but still it's a logic
error. Everything else can be simplified a bit taking that into account.
Some commands don't accept arguments, but users try giving them and don't
notice a mistake. It's a bit more user-friendly to tell the user that there is
something wrong with the way he tries to use the command.
1. Keep initDone check only for the places where cache is directly accessed.
We don't need to check it in other places, otherwise we have a mess of
duplicating checks.
2. Fix bug in code related to block deserialisation. There's no magic, so
checking that initialisation is done is not enough for proper block
deserialisation. We need to manually fill StateRootEnabled field.
3. Since transaction doesn't need network magic to compute its hash, we don't
need to perform Client initialisation before transaction-related requests.
4. Check that cache is initialised before accessing network magic.
5. Refactor the way Policy contract hash is fetched for Client requests.
We don't really need Client initialisation for that, it's OK to fetch Policy
hash on-the-fly.
Provide cosigners explicitly during deploy and don't read wallet twice.
This is needed because manifest validation requires valid sender address.

Sometimes on-chain invocations need a bit more GAS than expected after test
invocations, so let the user compensate for that. 2.x has similar option since
483fefbb62.
On many occassions we can determine at compile-time if contract config lacks
some properties it needs. This includes all native contract invocations
through stdlib, as both hashes and methods are known at compile-time
there.

We have a lot of common code which is shared between `smartcontract` and
`wallet` cli packages. It's convinient to keep it in a separate helper
package in order to avoid functional cli packages dependencies.
