e0ab4ec6f0 core: adjust helper test contract 
Method is allowed to have single return value on stack after its invocation.
Make sure that test contract follows this rule.

13252bb941 core: refactor helper test contracts generation 
* Move generator to a separate package.

150041d25e core: unexport native Management's GetMinimumDeploymentFee 
This method is used only from Management contract. We also have
neotest-based tests for `getMinimumDeploymentFee`, it should be enough.

The only user of (*Block).Trim() is in DAO and it already has a nice buffer
usually, so creating another one makes no sense. It also simplifies error

a8d2df874f stackitem: limit JSON size in ToJSONWithTypes 
Also do not limit depth. It was introduced in e34fa2e915 as a simple
solution to OOM problem. In this commit we do exactly the refactoring
described there. Maximum size is the same as stack item size and
can be changed if needed withouth significat refactoring.
`1 MiB` seems sufficient, though.

1. Move redirections check to the tcp level. Manually resolve request address
and create connection for the first suitable resolved address.
2. Remove URIValidator. Redirections checks are set in the custom http client,
so the user should take care of validation by himself when customizing the
client.

0092330fe1 rpc: carefully review places where Client.cache.initDone is used 
1. Keep initDone check only for the places where cache is directly accessed.
   We don't need to check it in other places, otherwise we have a mess of
   duplicating checks.
2. Fix bug in code related to block deserialisation. There's no magic, so
   checking that initialisation is done is not enough for proper block
   deserialisation. We need to manually fill StateRootEnabled field.
3. Since transaction doesn't need network magic to compute its hash, we don't
   need to perform Client initialisation before transaction-related requests.
4. Check that cache is initialised before accessing network magic.
5. Refactor the way Policy contract hash is fetched for Client requests.
   We don't really need Client initialisation for that, it's OK to fetch Policy
   hash on-the-fly.

e8ec820d2e vm: add unload command 
When execution fails it's the only way to change the prompt showing the
last executed instruction. Example:

```
NEO-GO-VM > loadgo examples/engine/engine.go
READY: loaded 117 instructions
NEO-GO-VM 0 > run
Error: at instruction 3 (SYSCALL): failed to invoke syscall 805851437: syscall not found
NEO-GO-VM 8 > parse
Error: missing argument
NEO-GO-VM 8 > parse 123
Integer to Hex			7b
Integer to Base64		ew==
String to Hex			313233
String to Base64		MTIz

NEO-GO-VM 8 > unload
NEO-GO-VM > exit

```

de2579ec07 dao: put contract IDs into keys using big endianness 
We don't have a need to iterate over them at the moment, but since we're
changing the DB format in the next release anyway let's add this ability also,
just in case.

f80680187e storage: expose private storage map for more efficient MPT batch 
It couldn't be done previously with two maps and mixed storage, but now all of
the storage changes are located in a single map, so it's trivial to do exact
slice allocations and avoid string->[]byte conversions.

7dc8fc443f dao: simplify buffer management for private DAO 
Private DAO is only used in a single thread which means we can safely reuse
key/data buffers most of the time and handle it all in DAO.

Doesn't affect any benchmarks.

9bfb3357f2 storage: add "private" mode to MemCachedStore 
Most of the time we don't need locking on the higher-level stores and we drop
them after Persist, so that's what private MemCachedStore is for.

It doesn't improve things in any noticeable way, some ~1% can be observed in
neo-bench under various loads and even less than that in chain processing. But
it seems to be a bit better anyway (less allocations, less locks).

aefb26255a dao: drop DAO interface

implementations, now it makes zero sense.

9d2ef775cf storage: simplify (*MemCachedStore).Put/Delete interface 
They never return errors, so their interface should reflect that. This allows
to remove quite a lot of useless and never tested code.

Notice that Get still does return an error. It can be made not to do that, but
usually we need to differentiate between successful/unsuccessful accesses
anyway, so this doesn't help much.

17a43b19e0 storage: remove Batch from Store 
We never use it for real underlying stores, so these implementations are
useless (everything goes though PutChangeSet now).

35bdfc5eca storage: use two maps for MemoryStore 
Simple and dumb as it is, this allows to separate contract storage from other
things and dramatically improve Seek() time over storage (even though it's
still unordered!) which in turn improves block processing speed.

neo-bench performance is mostly unaffected, ~0.5% for 1-1 test and 4% for
10K-10K test both fall within regular test error range.
