79b1bf72aa native: check that oracle request GAS IsInt64()
We use int64 value down below, so check for IsInt64() while MinimumResponseGas
check still covers for values less than zero.

5f13de3a76 *: simplify some integer checks with IsUint64()
If we need a positive number we can do `IsUint64()` instead of checking that
`Int64()` is `> 0`.

233307aca5 stackitem: completely drop MaxArraySize
Turns out C# VM doesn't have it since preview2, so our limiting of
MaxArraySize in incompatible with it. Removing this limit shouldn't be a
problem with the reference counter we have, both APPEND and SETITEM add things
to reference counter and we can't exceed MaxStackSize. PACK on the other hand
can't get more than MaxStackSize-1 of input elements.

Unify NEWSTRUCT with NEWARRAY* and use better integer checks at the same time.

Multisig limit is still 1024.

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.

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.

Resulting item can't have more than MaxStackSize elements. Technically this

stack). See neo-project/neo#2534, thanks @vang1ong7ang.
