ec58bec803 compiler: fix global constant traversal
There can be no global variables, but some global constants.

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()`.

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.

e.g. we can use some syscall inside.

initialization is performed.

a781d299e0 compiler: use fully-qualified names for tracking functions
Function name now consists of 3 parts:
1) full package path
2) method receiver type (if any)
3) function name itself .

Fix #1150.

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.

d2ddf7b7cb *: support invoking methods by offset
Allow to invoke methods by offset:
1. Every invoked contract must have manifest.
2. Check arguments count on invocation.
3. Change AppCall to a regular syscall.
4. Add test suite for `System.Contract.Call`.

e87eba51f9 compiler: emit bytecode for unused exported functions

This will be needed later when arbitrary method calls are allowed.

ed45ff98e3 compiler: process interop together with package
Closes #913.
Provide package info in the funcScope to check if function is defined
insided an interop package. As a good side-effect bytecode for builtins from `util`
is no longer emitted.

Related #941.

5b0e73ddf0 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.

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.

we do not clean altstack properly. This commit fixes it.

3cbd138b67 compiler: allow to declare variables of struct type
Previously, struct variables were initialize with VM's nil value
which is of primitive type. Thus SETITEM used for struct's field
updating wasn't working.

Previously this declarations were ignored which resulted

and can't be converted to an array.
