Mostly it's about Go 1.22+ syntax with ranging over integers, but it also
prefers ranging over slices where possible (it makes code a little better to
read).
Notice that we have a number of dangerous loops where slices are mutated
during loop execution, many of these can't be converted since we need proper
length evalutation at every iteration.

It's slightly less efficient (all comparisons are always made), but for
strings/ints it's negligible performance difference, while the code looks a
tiny bit better.

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).

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'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.

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.

And refactor some code a bit, don't use bytes.Clone where type-specific
helpers may be used instead.

It's a bug since Prefix is shared between all iterator items and
appending is not enough. If prefix has enough capacity, then new slice
won't be created and the previous item's prefix will be changed.
This commit fixes the following test failure caused by moving from
bytes.Clone to slice.Copy:

This method returns persisted block height and doesn't take into account
persisting block height. Some of the callers of this method relay on
the wrong assumption that BlockHeight() returns persisting block index.

Our wrapping optimization relied on the caller context having a TRY block,
but each context (including internal calls!) has an exception handling stack
of its own, which means that for an invocation stack of
entry
A.someMethodFromEntry() # this one has a TRY
A.internalMethodViaCALL() # this one doesn't
B.someMethod()
we get `HasTryBlock() == false` for `A.internalMethodViaCALL()` context, which
leads to missing wrapper and missing rollbacks if B is to THROW. What this
patch does instead is it checks for any context within contract boundaries.
Fixes#3045.

Make the contracts cache initialization unified. The order of cache
iniitialization is not important and Nottary contract is added to the
bc.contracts.Contracts wrt P2PSigExtensions setting, thus no functional
changes, just refactoring for future applications.

Everywhere including examples, external interop APIs, bindings generators
code and in other valuable places. A couple of `interface{}` usages are
intentionally left in the CHANGELOG.md, documentation and tests.
And include some node-specific configurations there with backwards
compatibility. Note that in the future we'll remove Ledger's
fields from the ProtocolConfiguration and it'll be possible to access them in
Blockchain directly (not via .Ledger).
The other option tried was using two configuration types separately, but that
incurs more changes to the codebase, single structure that behaves almost like
the old one is better for backwards compatibility.
Fixes#2676.
We don't use all of the Stack functionality for it, so drop useless methods
and avoid some interface conversions. It increases single-node TPS by about
0.9%, so nothing really important there, but not a bad change either. Maybe it
can be reworked again with generics though.
