ee4a647934 stackitem: limit EQUAL for deeply nested structs

df2430d5e4 stackitem: limit deserialization to MaxDeserialized items 
Follow neo-project/neo#2531. Even though it's not strictly required (our node
handles problematic script just fine) we better be compliant wrt
deserialization behavior. MaxDeserialized is introduced to avoid moving
MaxStackSize which is a VM parameter.

aab18c3083 stackitem: introduce Convertible interface 
We have a lot of native contract types that are converted to stack items
before serialization, then deserialized as stack items and converted back to
regular structures. stackitem.Convertible allows to remove a lot of repetitive
io.Serializable code.

This also introduces to/from converter in testserdes which unfortunately
required to change util tests to avoid circular references.

2d993d0da5 state: store notary deposit as stackitem 
Which is less effective, but makes it more similar to other native contracts
that are supposed to be contracts anyway.

fbe8bd2d9c stackitem: limit deserialized arrays/maps 
See neo-project/neo#2531, even though they use MaxStackSize there resulting
element is not valid unless it has <=MaxArraySize elements.

also neo-project/neo-vm#422.

eb7bd7b99b core: optimize storageFind 
Because `Map` stores elements in arbitrary order, addition of new
element takes linear time (`Index` iterates over all keys). Thus our
`storageFind` is actually quadratic in time. Optimize this by creating
map from sorted slice.

cfe41abd35 vm: fix OOM during nested structure cloning 
Resulting item can't have more than MaxStackSize elements. Technically this
limits to MaxStackSize cloned elements but it's considered to be enough to
mitigate the issue (the next size check is going to happen during push to the
stack). See neo-project/neo#2534, thanks @vang1ong7ang.
