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.

there is no need to log it.

f2107bfbc4 compiler: copy structs when passing as arguments 
In Go structs must be copied when used as arguments.
To do so we must clone struct on VM level.
This is done by appending this struct to an intermediate array.

a781d299e0 compiler: use fully-qualified names for tracking functions

2) method receiver type (if any)
3) function name itself .

685d44dbc1 *: support _initialize method in contracts 
Invoke `_initialize` method on every call if present.
In NEO3 there is no entrypoint and methods are invoked by offset,
thus `Main` function is no longer required.
We still have special `Main` method in tests to simplify them.
