vm: cut trailing spaces in PrintOps
...
When there is a single big instruction (like PUSHDATA4) in script,
all other instructions are padded to the right with spaces.
This makes it hard to view script in terminal, because long lines
are usually wrapped at the screen boundary and printed as multiple lines.
The culprit is our `cursor` field which is printed in the last column
and causes all previous fields to have the same length for every
instruction. One way to fix this is to omit cursor field if it is empty.

Because `MaxKeySize` is bigger than integer size, we fail on integer

vm: rework stack as a simple slice
...
Double-linked list is quite expensive to manage especially given that it
requires microallocations for each Element. It can be replaced by simple slice
which is much more effective for simple push/pop operations that are very
typical in a VM. I've worried a little about more complex operations like
XDROP/1024 or REVERSEN/1024 because these require copying quite substantial
number of elements, but turns out these work fine too.
At the moment Element is kept as a convenient wrapper for Bytes/BigInt/Bool/etc
methods, but it can be changed in future. Many other potential optimizations
are also possible now.

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.

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.

core: move GetPrice from core
to interop
...
We have additional logic for getting BaseExecFee policy value. This
logic should be moved to interop context instead of being in Policer,
because Policer is just an interface over Policy contract.
After moving this logic to interop context, we need to use it to define
BaseExecFee instead of (Policer).BaseExecFee. Thus, moving
(*Blockchain).GetPrice to (*Context).GetPrice is necessary.
