Properly load the provided method using NEF and hash specified. It allows
to have NEF properly set in the VM context and handle CALLT instruction
correctly.

It's enough to specify the input file only to get the standard output:
```
$ neo-go contract compile -i ./1-print/1-print.go
$ neo-go contract compile -i ./1-print/
```

If `StartWhenSynchronized` is unset in config, `node` command runs RPC
service instantly. Previously there was a ground for deadlock. Command
started RPC server synchronously. According to server implementation, it
sends all internal failures to the parameterized error channel. Deadlock
occured because main routine didn't scan the channel.
Run `rpcsrv.Server.Start` in a separate go-routine in `startServer`.
This prevents potential deadlock caused by writing into unread channel.
Fixes#2896.

Everywhere including examples, external interop APIs, bindings generators
code and in other valuable places. A couple of `interface{}` usages are
intentionally left in the CHANGELOG.md, documentation and tests.
Do not add them directly to chain, it will be done by the block queue
manager. Close https://github.com/nspcc-dev/neo-go/issues/2923. However,
this commit is not valid without
https://github.com/roman-khimov/dbft/pull/4.
It's the neo-go's duty to initialize consensus after subsequent block
addition; the dBFT itself must wait for the neo-go to complete the block
addition and notify the dBFT, so that it can initialize at 0-th view to
collect the next block.
If NEP2 account label is not provided as a flag for import-related
CLI commands then ask it in the interactive mode.
This change breaks the compatibility with the old behaviour (add
the unnamed account if the name wasn't specified).
Fetch account's name from the CLI argument and do not ask for the
user's input if provided, close#2882. Fetch password from config
if provided, close#2883.
And include some node-specific configurations there with backwards
compatibility. Note that in the future we'll remove Ledger's
fields from the ProtocolConfiguration and it'll be possible to access them in
Blockchain directly (not via .Ledger).
The other option tried was using two configuration types separately, but that
incurs more changes to the codebase, single structure that behaves almost like
the old one is better for backwards compatibility.
Fixes#2676.
There are no changes visible from the user side (at least for those
users who doesn't put Prometheus's or pprof's port in quotes), just
internal refactoring. From now and on, BasicService configuration is
used by RPC server config, TLS for RPC server, pprof and Prometheus.
Follow neo-project/neo#2807. Notice that this data is not cached, our previous
implementation wasn't too and it shouldn't be a problem (not on the hot path).
It's useful to reproduce different execution problems including executions
stopped because of GAS limit. Satoshi representation is deliberately used,
because that's what is usually found in logs.
Problem: failing part of TestLoad:
```
=== RUN TestLoad/loadgo,_check_signers
cli_test.go:160:
Error Trace: /home/circleci/go/src/github.com/nspcc-dev/neo-go/cli/vm/cli_test.go:160
/home/circleci/go/src/github.com/nspcc-dev/neo-go/cli/vm/cli_test.go:147
/home/circleci/go/src/github.com/nspcc-dev/neo-go/cli/vm/cli_test.go:444
Error: command took too long time
Test: TestLoad/loadgo,_check_signers
```
Solution: split the test into multiple parts to reduce test execution time.
And fix failing test along the way:
```

* strip NEP-XX methods before going into generator to avoid unused imports
* nepXX.Invoker types already include Call
* always import util, it's used for Hash
It makes sense in general (further narrowing down the time window when
transactions are processed by consensus thread) and it improves block times a
little too, especially in the 7+2 scenario.
Related to #2744.
1. UsageText shows the command usage rule. Fixed/added where needed.
2. Description shows the command description, huh. It is shown right after
UsageText, so there's no need to repeat the command usage rule. If
Description contains Example, then it should be printed on a new line.
Usage message is shown on common --help command, thus it should be meaningful
and short. If user needs more detailed command description, then he can use
command-specific help.
As a result, current VM help looks pretty simple:
```

Share parameters parsing code between 'contract invokefunction' and
'vm run' commands. It allows VM CLI to parse more complicated parameter
types including arrays and file-backed bytestrings.
