eb224aeebe vm: add some checks for OVER and PICK, add OVER tests
These actually behaved correctly because of deferred sigsegv recover, but I
think it would be nice to print something more meaningful for users.

85831e3e92 vm: fix XTUCK implementation, add tests
The code that we have actually implements XTUCK and not TUCK. And it's a bit
broken, so fix it and add some tests. The most interesting one (that required
to touch stack code) is the one when we have 1 element on the stack and are
trying to tell XTUCK to push 2 elements deep.

b34a1b6c25 vm: harden tests against VM failures
Add a check for failed VM state, some of tests using logic values (like NZ
test) can succeed even with VM in FAULT state otherwise.

42dfca47cf vm: fix double VM run from CLI
Fixes one more instruction being ran when VM FAULTs:

NEO-GO-VM > run
NEO-GO-VM > error encountered at instruction 6 (ROLL)
NEO-GO-VM > runtime error: invalid memory address or nil pointer dereference
FAULT
NEO-GO-VM > error encountered at instruction 7 (SETITEM)
NEO-GO-VM > interface conversion: interface {} is []vm.StackItem, not []uint8

Refs. #96.

428e789ddc vm: produce better error for ROLL with wrong index
Current VM implementation doesn't return errors for many operations, so the
only way to handle it here is to check for NULL. Refs. #96.

ec7e17ffa6 pkg: make use of the new crypto/hash package
Simplifies a lot of code and removes some duplication. Unfortunately I had to
move test_util random functions in same commit to avoid cycle
dependencies. One of these random functions was also used in core/transaction
testing, to simplify things I've just dropped it there and used a static
string (which is nice to have for a test anyway).

There is still sha256 left in wallet (but it needs to pass Hash structure into
the signing function).

4ccda04eea compiler: fix string/numbers equality/inequality gen again
Unfortunately d58fbe0c88 didn't really fix the
problem because tinfo.Type (the expression resulting type) actually is a bool
and we need to check its parameters. Also, there is need to fix the NEQ
operation.

a1e3655560 interop: move into pkg/interop, replace pkg/vm/api
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.

7cd91610df compiler: quick and dirty inspection fix for JMP instrs
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.

810f096811 compiler: change codegen to emit NUMEQUAL instead of EQUAL
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.
