vm: harden SUBSTR implementation against bad index/offset values

The upper index bound for slices is capacity, not length. Check for negative
values also. Fixes #387 .

vm: protect PUSHDATA from short reads
...
Same thing done in a2a8981979
for PUSHBYTES,
failing to read the amount of bytes specified should lead to FAULT. Also
makes readUint16() and readUint32() panic as this is the behavior we want in
these cases. Add some tests along the way.

vm: return NOP as current instruction for just loaded VM
...
Before:
NEO-GO-VM > loadgo h.go
READY: loaded 16 instructions
NEO-GO-VM > ip
instruction pointer at -1 (PUSH0)
After:
NEO-GO-VM > loadgo h.go
READY: loaded 16 instructions
NEO-GO-VM > ip
instruction pointer at -1 (NOP)
I think NOP is a little less scary.

vm: expand instruction list with commands from current VM spec
...
Current NEO documentation lists them:
https://docs.neo.org/docs/en-us/tooldev/advanced/neo_vm.html
CALL_* instructions were left out because of conflict with golint (but they're
removed in NEO 3.0 anyway, so wasting time on them makes no sense).
Update autogenerated instruction_string.go accordingly.

These actually behaved correctly because of deferred sigsegv recover, but I
think it would be nice to print something more meaningful for users.
