neo-storm has developed more wrappers for syscall APIs, so they can and should
be used as a drop-in replacement for pkg/vm/api. Moving it out of vm, as it's
not exactly related to the VM itself.
These were interpreted completely wrong, they actually have two next bytes
indicating an offset. This patch is a quick fix, actually more work is needed
here to properly display various instructions.
This is wrong, see issue #294, but it makes our VM tests work (as VM is
missing EQUAL implementation), so until #294 is properly resolved we're better
have this kind of wrong code generation.
* Fixed bug in else stmts
* Fixed if else bug
* Back to %v for formatting instructions
Imported from CityOfZion/neo-storm (ea8440e1454207753c8d209ce7c2cf724fd4ea16).

* Compiler improvements
* Fixed Neo APIs naming convention
* Added NOP after syscall for matching AVM files with neo-python.
