286d9185f4 smartcontract: remove contract features
We're featureless now, all contracts have access to storage and payable status
is to be determined via new NEP. Follow neo-project/neo#2060.

01ccaefe2f compiler: refactor void calls processing
Call result is not used only if it occurs inside a `ExprStmt`.
Otherwise (`IfStmt`, `BinExpr`...) it is used.

Fix #1495.

1f2d76a1c2 compiler: fix manifest method offset
While optimizing jumps, old offsets should be compared
with the method offset before optimization, not with
the constantly changing value.

f8d5c40928 compiler: do not DROP return value with type assertion
The same problem as with IF. Example:

```
func foo() interface{} {
    ...
}

func Main() int{} {
   return foo().(int)    <--- panic here
}
```

dbce3c9a19 compiler: do not DROP unary expression value inside IF stmt
We dropped values from such calls because they where marked as unused
(consequently, were followed by DROP instructions). Example:

if !foo() {    <--- panic here
    ...
}

This commit prevents the following runtime error during script execution:
```
"error encountered at instruction ** (NOT): runtime error: invalid memory address or nil pointer dereference"

```

6701e8cda0 compiler: allow to use local variables in init()
Because body of multiple `init()` functions constitute single
method in contract, we initialize slot with maximum amount of
locals encounterered in any of `init()` functions and clear them
before emitting body of each instance of `init()`.

fd52dee79f compiler: process literals in analyzeVoidCalls
Function call can occur in the slice or map literal
and its result surely isn't unused.

bcc11cbd74 compiler: support removing slice elements
Go-way of removing elements from slice is via `append` builtin.
There is a separate opcode for removing elements from
Arrays, which is cheaper and supported in this commit.

78948ef7af compiler: emit error for non-byte subslices
They are not supported for now, as VM has only
`SUBSTR` opcode for Buffers (`[]byte` in Go).

37f7363386 interop: return struct pointers where needed
`Transaction`, `Block` and `Contract` are represented as
`Array`s in VM, so we must return pointers.

3d8c7af66c compiler: handle void call to recover()
Other builtins such as `len` and `make` can be ignored,
because not-assigning `make` result is catched by parser.
