This also removes bigint.FromBytesUnsigned(), it's not used very often and
it's somewhat misleading in the bigint package (which is supposed to use a
very specific enconding).

2. Replace pre-defined constant deployment fee by calculated one.
This change is needed to be able to properly collect coverage for

9 fields vs 10, notice the primary index right after the block number.
Back when ac527650eb initially added Ledger I've
used https://github.com/neo-project/neo/pull/2215 as a reference and it was
correct (no primary index). But then https://github.com/neo-project/neo/pull/2296
came into the C# codebase and while it looked like a pure refactoring it
actually did add the primary index as well and this wasn't noticed. It wasn't
noticed even when 3a4e0caeb8 had touched some
nearby code. In short, we had a completely wrong implementation of this call
for more than three years. But looks like it's not a very popular one.

Refs. #3522. The core problem is the same as for groups/features: we can't
allow empty trusts when they're unmarshalled from JSON. But unlike others we
can't easily differentiate missing any value with other cases because the
default value for WildPermissionDescs is a valid thing. Adding an additional
field makes it invalid and we can build around it. Other options are
implementing custom UnmarshalJSON for Manifest (too much for this) or making
Trusts a pointer (an option, but can fail in too many ways).

It should be sufficient to retrieve next block validators once per
updateExtensibleWhitelist call and then reuse this value. `nextVals`
copy intentionally omitted since the only change that
smartcontract.CreateDefaultMultiSigRedeemScript performs over the
`nextVals` list is sorting.

It's not correct to use an updated contract state got from Management to
check for the allowed method call. We need to use manifest from the
currently executing context for that. It may be critical for cases when
executing contract is being updated firstly, and after that calls
another contract. So we need an old (executing) contract manifest for
this check.
This change likely does not affect the mainnet's state since it's hard
to meet the trigger criteria, but I'd put it under the hardfork anyway.

This test ensures that NeoGo node doesn't have the DeepCopy problem
described in https://github.com/neo-project/neo/issues/3300 and fixed in
https://github.com/neo-project/neo/pull/3301. This problem leads to the
fact that Notifications items are not being properly refcounted by C#
node which leads to possibility to build an enormously large object on
stack. Go node doesn't have this problem.
The reason (at least, as I understand it) is in the fact that C# node
performs objects refcounting inside the DeepCopy even if the object
itself is not yet on stack. I.e. System.Runtime.Notify handler
immediately adds references to the notification argumetns inside
DeepCopy:
b1d27f0189/src/Neo.VM/Types/Array.cs (L108)b1d27f0189/src/Neo.VM/Types/Array.cs (L75)
Whereas Go node just performs the honest DeepCopy without references counting:
b66cea5ccc/pkg/vm/stackitem/item.go (L1223)
Going further, C# node clears refs for notification arguments (for array
and underlying array items). System.Runtime.GetNotifications pushes the
notificaiton args array back on stack and increments counter only for
the external array, not for its arguments. Which results in negative
refcounter once notificaiton is removed from the stack. The fix itself
(f471c0542d/src/Neo/SmartContract/NotifyEventArgs.cs (L84))
doesn't need to be ported to NeoGo because Go node adds object to the
refcounter only at the moment when it's being pushed to stack by
System.Runtime.GetNotifications handler. This object is treated as new
object since it was deepcopied earlier by System.Runtime.Notify handler:
b66cea5ccc/pkg/vm/stack.go (L178).
Thus, no functoinal changes from the NeoGo side. And we won't
intentionally break our node to follow C# pre-Domovoi invalid behaviour.

Do not use the updated contract state from native Management to perform
permissions checks. We need to use the currently executing state
instead got from the currently executing VM context until context is
unloaded.

Account is blocked when it's in the Policy's storage, not when it's
missing from the Policy storage. Introduced in
bbbc6805a8.
This bug leads to the fact that during native Neo cache initialization
at the last block in the dBFT epoch, all candidates accounts are
"blocked", and thus, stand-by committee and validators are used in the
subsequent new epoch. Close#3424.
This bug may lead to the consequences described in #3273, but it needs
to be confirmed.
