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:
```

```
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.
CLI:
* Typos are fixed
* Documentation on NEP-11 tokens is added
* NeoGo node configuration is moved to a separate file
Compiler:
* Typos and indentations are fixed
* Ops dump example is updated
Consensus:
* Typos are fixed
* Links are fixed
Notifications:
* Minor adjustments
RPC:
* `getversion` response is updated
* `getunclamedgas` comment is removed (not valid since
https://github.com/neo-project/neo-modules/pull/243)
VM:
* Update help message
* `load*` command adjustments
* `astack` command removal
Provide cosigners explicitly during deploy and don't read wallet twice.
This is needed because manifest validation requires valid sender address.

If wallet size decreases, we need to remove trailing garbage if it
exists. This can happen when removing account or reading pretty-printed
wallet. It doesn't affect our CLI (we decode only file prefix), but
it is nice to always have a valid JSON file.

Implement a way to check if tx has been persisted on blockchain and
to get general info about transaction. Much more convenient than
handwritten curl queries.

Sometimes on-chain invocations need a bit more GAS than expected after test
invocations, so let the user compensate for that. 2.x has similar option since
483fefbb62.
On many occassions we can determine at compile-time if contract config lacks
some properties it needs. This includes all native contract invocations
through stdlib, as both hashes and methods are known at compile-time
there.

Error: Expect "{"name":"HASHY 3HNCEX8D9J0p\u002BLxmr3uPhOhSW90="}" to match "{"name":"HASHY 3HNCEX8D9J0p+Lxmr3uPhOhSW90="}"
Test: TestNEP11_OwnerOf_BalanceOf_Transfer
```
Solution:
Same as preesnted in #2006.
Base58 does not preserve one-to-one byte correspondence with the
original data, so different combinations of the same number of bytes
might have different encoded string length. We use GAS transfer to mint
HASHY token, where the token hash is Base58Encode(Ripemd160(data + txHash)).
The problem is that `invokescript` RPC call is used to define transfer tx
sysfee, thus, txHash during testinvoke differs from the actual one, that's
why resulting token ID may have different length during testinvoke and
real invoke. As far as we use token ID as a key to store contract
values, the storage price may also differ. The result is failing
TestNEP11_OwnerOf_BalanceOf_Transfer test due to `gas limit exceeded`
error:
```

Fixed by using base64 instead of base58 (base64 preserves the resulting
encoded string length for the same input length).
Create local variables as they are needed and remove `INITSLOT`
if there were no locals. This helps to eliminate a whole class
of bugs when calculated and real amount mismatched.
