compiler: initialize struct fields explicitly
...
By default VM initializes every field of a new struct to a Boolean.
If field contains another struct, we need to initialize it to default
value explicitly. This commit sets default values for uninitialized
field.

It is more convenient to drop values inside `emitStoreVar` because this

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.

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 ).
