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.

vm,compiler: replace APPCALL with System.Contract.Call
...
Contract calls are performed via syscall System.Contract.Call
in NEO3. This implements this in compiler and removes APPCALL from the
VM.

vm: implement ASSERT/ABORT opcodes
...
Rename THROWIFNOT to ASSERT, add ABORT opcode.
ABORT cannot be caught, but the implementation should be postponed until
exception handling is implemented.

vm: remove crypto-related opcodes
...
All cryptography has moved to interops in NEO3.
There is no SHA256 interop RN, but it is to appear later.
Closes #777 .

vm: move opcodes into their own package
...
This allows easier reuse of opcodes and in some cases allows to eliminate
dependencies on the whole vm package, like in compiler that only needs opcodes
and doesn't care about VM for any other purpose.
And yes, they're opcodes because an instruction is a whole thing with
operands, that's what context.Next() returns.
