17f3a21e27 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.

fc1075bf75 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.

convenience. Fixes #195.

974f5db6bc vm: add a TUCK implementation with tests 
Also fix stack's InsertAt for the edge case of inserting into a position that
currently is empty (the first good TUCK test illustrates this).

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.

33c512032f vm: switch from Opcode to Instruction 
Which matches the changes done in neo-storm and also make this codebase closer
to the `dev` branch (that also uses Instruction).
