1611ede58c crypto/keys: implement NewPublicKeyFromBytes()
It is convenient to have a single function instead of
allocating new `PublicKey` and using `DecodeBytes()` on it.

efddcf3bfe core: remove interop methods from interopContext
If interops are defined as a separate functions
they can be implemented in a separate packages
which can help us to structure core.

2d0ad30fcf vm: rework Map with internal slice representation
Which makes iterating over map stable which is important for serialization and
and even fixes occasional test failures. We use the same ordering here as
NEO 3.0 uses, but it should also be fine for NEO 2.0 because it has no
defined order.

e6e8761d35 core: fix contract's state migration and don't swallow errors
Fixes difference in state changes at mainnet's block 2442790 because contract
migration in b4eb2dc35226e6520ee4e09a56197dff91547b50a7f57edc82930fc18c75dffc
doesn't actually transfer the storage state, it only deletes the old one.

And add an error check just in case.

ced5ddbb9e core: fix wrong references ordering in interop function
Broken by 9f7018503a. Almost the same problem as
in 01082a8988 (though it is deterministic now,
just not the way the contract expects).

a9abd3d841 core: fix wrong endian used in interop functions
C# uses ToArray() or UintXXX(bytes) here which interprets hashes as they
should be interpreted (BE, although they always convert to LE when converting
to String just for the fun of it). It leads to state difference for us at
block 2025204 where even though we have the same value for the key, the key
itself differs, ours:

dd2b538e2a0c1db1ae5061c15be14f916bd1e678e512ffcda6d9499d8e7fe97ee71fd6b8004583d9afe09cc4dadbd5deb63d01e061009b7cffdaa674beae0f930ebe6085af900093e5fe56b34a5c220ccdcf6efc336fc5000000000000000000000000000000000010

dd2b538e2a0c1db1ae5061c15be14f916bd1e67861e0013db6ded5dbdac49ce0afd9834500b8d61fe77ee97f8e9d49d9a6cdff12e5009b7cffdaa674beae0f930ebe6085af900093e5fe56b34a5c220ccdcf6efc336fc5000000000000000000000000000000000010

In this key there is a tx hash encoded
(e512ffcda6d9499d8e7fe97ee71fd6b84583d9afe09cc4dadbd5deb63d01e061 in LE used
by all the tools like neoscan).

I love Neo.

f1856bfa8b core/tx: remove publickey indirection from assets and txes
It makes very little sense having pointers here, these structures MUST have
some kind of key and this key is not gonna be wandering somewhere on its
own. Fixes a part of #519.

7e371588a7 core/tx: remove one layer of indirection for scripts and inouts
It reduces heap pressure a little for these elements as we don't have to
allocate/free them individually. And they're directly tied to transactions or
block, not being shared or anything like that, so it makes little sense for
them to be pointer-based. It only makes building transactions a little easier,
but that's obviously a minor usecase.
