05f3329ec0 vm: add IterBack to the Stack to iterate bottom-to-top
And use it to build user-facing stack representation because that's the order
that C# VM uses.

7080b78a6b vm: fix a bug in collection serialize
When encountering already seen stack item we should fail
only if it is a collection. Duplicate Integers or ByteArrays are ok
because they can't lead to recursion.

e319c6c638 cli: move avm inspect from vm to contract command

end this makes our CLI interface more consistent and usable. Drop useless

b2609786e9 vm: copy slice in NEWARRAY/NEWSTRUCT
When performing NEWARRAY on a Struct or NEWSTRUCT on a Array,
underlying slice needs to be copied, because when it's capacity
doesn't matches it's length, underlying storage will be used
for appends even if it is already pointed at by another slice.

1bf232ad50 vm: introduce TryBool() for Element and use it in VerifyWitnesses
Script can return non-bool results that can still be converted to bool
according to the usual VM rules. Unfortunately Bool() panics if this
conversion fails which is OK for things done in vm.execute(), but certainly
not for VerifyWitnesses(), thus there is a need for TryBool() that will just
return an error in this case.

d62a367900 vm: add Value() method to Element
