e21015233b compiler: implement shadowing of global variables
Before introducing slots it was hard to change global variables
preserving changes across multiple function calls.
This commit implements such possibility.
Closes #638.

0cb6dc47e4 vm: implement slot-related opcodes
1. Slot is a new mechanism for storing variables during execution
which is more convenient than alt.stack. This commit implements
support for slot opcodes in both vm and compiler.
2. Remove old alt.stack opcodes.
3. Do not process globals at the start of every function, but instead
load them single time at main.

73c82584a3 vm,compiler: replace APPCALL with System.Contract.Call
Contract calls are performed via syscall System.Contract.Call
in NEO3. This implements this in compiler and removes APPCALL from the
VM.

7ac15a7557 compiler: support implicit type in function arguments
Go supports declaring multiple arguments of the same type without
duplicating type name. Now we support this too.

156a2eddc5 compiler: support using return in some branches
When `return` is used in one codepath, but not the other,
we do not clean altstack properly. This commit fixes it.

2ec1d76320 compiler: add ability to generate .abi.json file
A part of integration with NEO Blockchain Toolkit (see #902). To be
able to deploy smart-contract compiled with neo-go compiler via NEO
Express, we have to generate additional .abi.json file. This file
contains the following information:
 - hash of the compiled contract
 - smart-contract metadata (title, description, version, author,
email, has-storage, has-dynamic-invoke, is-payable)
 - smart-contract entry point
 - functions
 - events

However, this .abi.json file is slightly different from the one,
described in manifest.go, so we have to add auxilaury stractures for
json marshalling. The .abi.json format used by NEO-Express is described
[here](https://github.com/neo-project/neo-devpack-dotnet/blob/master/src/Neo.Compiler.MSIL/FuncExport.cs#L66).

ab7f2cb4fb compiler: fix bug with missing methods parameters
Method `methodInfoFromScope(...)` always returned an empty parameters
set, so we were missing this information in both .abi.json and
.debug.json files. Fixed now.

Sequence points is a way to map a specific instruction offset
from a compiled contract to a text span in a source file.

This commit implements mapping only for `return` statements.
Further improvements are straight-forward.

3cbd138b67 compiler: allow to declare variables of struct type

and can't be converted to an array.

b461a6ab63 compiler: do not short-circuit in complex conditions
Current implementation of short-circuting is just plain wrong
as it uses `last` or `before-last` labels which meaning depend
on context. It doesn't even handle simple assignements like
`a := x == 1 && y == 2`.

This commit makes all jumps in such conditions local
and adds tests.

Closes #699, #700.
