7287c01bd0 rpc/server: rework submitblock empty test 
The original intention here was to check for server reaction in presence of
validation errors (response.ErrValidationFailed) and it was very easy to make
validation fail for block without transactions in Neo 2. But in Neo 3
transactionless blocks are perfectly valid (see
29d321b5e1) which broke this test even though we
didn't see it until websocket addition (which required
8cec6694ae to make this test work initially).

So make a valid block and then spoil its verification script.

fd72f0635e rpc/server: prevent test panicing in checkErrGetResult() 
If we expect some resp.Error, then check for it explicitly.

315aabde56 client: make http.Client internal to the Client 
Exposing it the outside users is strange, so incapsulate it completely.

Fix DialTimeout setting along the way, handle negative timeouts as invalid.

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.

c8328981ec vm: refactor tests 
Most of the tests follow the same logic:
push items on stack -> execute program -> check single result.
