Currently we can't properly stop running server on Windows and SIGHUP
is also not supported. This leads to occupied resources and failed
test cleanup:
```

Blockchain occupies resources (e.g. it opens log files for DB, etc.)
on creation and running. We need to release these resources if something
goes wrong during execution chain-related commands.
This commit solves the following problem on Windows:

This commit also unifies blockchain and services releasing code.
zap never closes open sinks except its own tests. This behaviour
prevents TestHandleLoggingParams from successful cleanup because
temp log output file can't be closed due to the following error:
```
TempDir RemoveAll cleanup: remove C:\\Users\\Anna\\AppData\\Local\\Temp\\TestHandleLoggingParams_debug5796883
33\\001\\file.log: The process cannot access the file because it is being used by another process.
```
So this tremendous cludge is made mosetly for our testing code.
It is not for concurrent usage (we don't have cases of
multithreaded access to logger output sink).
Notice that it makes the node accept Extensible payloads with any category
which is the same way C# node works. We're trusting Extensible senders,
improper payloads are harmless until they DoS the network, but we have some
protections against that too (and spamming with proper category doesn't differ
a lot).
Unfortunately, testing this code is not possible without an additional wrapper
in `input`, but adding it just to test this seems to be too excessive. Fixes
Problem:
```
--- FAIL: TestDumpDB (0.08s)
--- FAIL: TestDumpDB/too_low_chain
testing.go:894: TempDir RemoveAll cleanup: remove C:\Users\Anna\AppData\Local\Temp\TestDumpDB_too_low_chain357310492\001\chains\privnet\000001.log: The process cannot access the file because it is being used by another process.
```
Solution:
Release resources occupied by the chain even on non-error command exit.

```

```
Solution:
Currently no solution is implemented, but we can use relative paths instead of absolute.
We use 2 prefixes for storing items because of state synchronization.
This commit allows to parametrize dao with the default prefix.

It doesn't trigger the problem fixed in the previous commit because here
CreateTxFromScript is used with pre-calculated GAS value from InvokeFunction
and thus it's not performing invocation. Still, it's a nice test extension.
Standards are NEP-11 and NEP-17, not NEP11, not NEP17, not anything
else. Variable/function names of course can use whatever fits, but documents
and comments should be consistent wrt this.
