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 .

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.

3. Change AppCall to a regular syscall.

a1f98f92fe compiler: add ConvertResultToStruct flag
Part of #1055.

There'll be a lot of interops which result with a struct on stack instead
of interop interface, and sometimes their names are the same, so it's
unrelyable to take into account interop name only and don't pay
attention to it's API (package).

Also sort syscalls by package and name.

3729865860 compiler: reimplement for-range loops without syscalls
System.Enumerator.Next costs 1_000_000 gas which is rather big for a

This approach will use 2 PICKITEMS (270_000 gas) for maps, which is
still cheaper that *.Next syscall.

a986e2a064 *: drop support for old on-chain assets
You no longer can transfer them, so creating/renewing/storing doesn't make
much sense.

21efccd300 transaction: remove type field, set Version to 0
Two changes being done here, because they require a lot of updates to
tests. Now we're back into version 0 and we only have one type of
transaction.

It also removes GetType and GetScript interops, both are obsolete in Neo 3.

e32d0e01af compiler|transaction: remove transaction.GetUnspentCoins support
It's useless. Even though there is Neo.Transaction.GetUnspentCoins syscall
that can be used, its return type is an interop structure that's not accepted
by any other syscall, so you can't really do anything with it. And there is no
such interface for the .net Framework.

There is no such syscall as Neo.Transaction.GetScript and GetScript should be
available for contract's use.

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.
