3be37e8c5b vm: check instruction offset is valid before subsequent IP move 
Reference implementation:
e167f03e25/src/neo-vm/ExecutionContext.cs (L77).

Turns out that exception-related code (try\finally handling) is the only
place where next instruction pointer bounds are not pre-checked before
assignment. This statement is true for both go and C# implementations.
However, C# code has duplicate check located inside the
InstructionPointer setter for all instructions except the
exception-related ones. Neo-go code doesn't perform this duplicate check.
Thus, C# VM FAULTs execution in case of invalid TRY/FINALLY offsets, and
neo-go VM does not.

This commit reverts a part of
https://github.com/nspcc-dev/neo-go/pull/2396. This bug is discovered
thanks to test added in https://github.com/neo-project/neo-vm/pull/453.

process includes the following steps: create a wrapper over

persist (or discard) changes.
2. Split contract getters to read-only and read-and-change. Read-only
ones doesn't require the copy of an existing nativeCache item.
Read-and-change ones create a copy and after that change the copy.

9862b40f2c rpc: support InitialGasDistribution response from old Neo-Go nodes 
https://github.com/nspcc-dev/neo-go/pull/2435 breaks compatibility
between newer RPC clients and older RPC servers with the following
error:
```
failed to get network magic: json: cannot unmarshal string into Go struct field Protocol.protocol.initialgasdistribution of type int64
```

This behaviour is expected, but we can't allow this radical change.
Thus, the following solution is implemented:
1. RPC server responds with proper non-stringified
   InitialGasDistribution value. The value represents an integral
   of fixed8 multiplied by the decimals.
2. RPC client is able to distinguish older and newer responses. For
   older one the stringified value without decimals part is
   expected. For newer responses the int64 value with decimal part
   is expected.

The cludge will be present in the code for a while until nodes of
version <=0.98.3 become completely absolete.

it happens during service restart, the old server will be dead irrespective of
this error (if this affects new one in any way we'll know it soon).

d3672eb14a core: use BaseExecFee from InteropContext instead of Blockchain's one

544f2c2cb2 core: use proper storage price within the whole interop context 
We shouldn't use StoragePrice from Blockchain because its dao doesn't
contain the whole set of changes from previouse transactions in the
current block. Instead, we should use an updated storage price for
each transaction and retrieve the price from cached DAO.

Anna Shaleva
91a4bc5beb core: use proper DAO to get ExecFeeFactor 
The usage of the Blockchain's one leads to the same ExecFeeFactor within
a single block. What we need is to update ExecFeeFactor after each
transaction invocation, thus, cached DAO should be used as it contains
all relevant changes.

f5d5019b70 compiler: use absolute paths for debug data 
It's not a perfect thing, but neo-debugger just doesn't work at all with
relative pathes. Notice that `saveSequencePoint` still used absolute ones
leading to invalid debug.json data, but fixing it there doesn't help,
neo-debugger can't load source code using relatives.

5616585697 block/dao: simplify trimming, avoid allocations 
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
handling a lot.

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

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.

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).

anyway, so this doesn't help much.
