07ee7f7e12 compiler: allow multi-return variables declaration
Problem: an attempt to compile the following code leads to a runtime
panic:
```
package foo
var a, b = f()
func Main() int {
	return a + b
}
func f() (int, int) {
	return 1, 2
}
```

```
panic: runtime error: index out of range [1] with length 1 [recovered]
	panic: runtime error: index out of range [1] with length 1

Solution:

Allow using multi-return function calls as general variable declaration
value. It was supported for assignment statements, so do the same for
*ast.GenDecl if it's a variable under the hood.

5d5455312a rpcclient: add policy package for the PolicyContract contract
And test it with the RPC server.

Notice that getters still return int64 instead of *big.Int, that's because
these values are very limited and technically could even fit into an int (but
that seems to be too dangerous to use for long-term compatibility).

8385efe4b3 cli: simplify and fix invokeWithArgs logic
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.

Somewhat similar to invoker, but changing the state (or just creating a
