a3dacd3b74 tests: replace t.Fatal with require where possible
This makes tests less verbose and unifies the style
they are written in.

a7457d08a1 vm/core: add ID support for SYSCALL, redo interop registration
This solves two problems:
 * adds support for shortened SYSCALL form that uses IDs (similar to #434, but
   for NEO 2.0, supporting both forms), which is important for compatibility
   with C# node and mainnet chain that uses it from some height
 * reworks interop plugging to use callbacks rather than appending to the map,
   these map mangling functions are clearly visible in the VM profiling
   statistics and we want spawning a VM to be fast, so it makes sense
   optimizing it. This change moves most of the work to the init() phase
   making VM setup cheaper.

Caveats:
 * InteropNameToID accepts `[]byte` because that's the thing we have in
   SYSCALL processing and that's the most often usecase for it, it leads to
   some conversions in other places but that's acceptable because those are
   either tests or init()
 * three getInterop functions are: `getDefaultVMInterop`, `getSystemInterop`
   and `getNeoInterop`

Our 100K (1.4M->1.5M) block import time improves by ~4% with this change.

becd4f2333 vm: force neo-vm tests presence
We succeeded this test without running anything real which is certainly not
good and I think we should always run this tests.

8d4dd2d2e1 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.
