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:444
Error: command took too long time

```
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.
The tests are still there, coverage should counted fine, but it improves things:

Still a nice thing to have.
Make NEP-11 code use getnep11balances the same way NEP-17 code uses
getnep17balances. This command was introduced well before getnep11balances
appeared, so it required always specifying contract explicitly. Now this
constraint can be relaxed somewhat in most cases.
1. In the single token mode compare known hashes instead of names, names can
be misleading.
2. Hardcode NEO/GAS, they are special (if not overrided by the wallet data).
We have this data available since 0.99.1 while all public networks require at
least 0.99.2 for compatibility and NeoFS setups use 0.99.2+ too. This data can
simplify account handling considerably making additional requests unneccessary
in many cases.
In the same way we do for NEP-17 tokens. This code predates "getnep11balances"
call, so this wasn't possible back then, but now we can improve the situation
(allow specifying names/symbols instead of hashes only).
Unfortunately Go doesn't allow to easily reuse readers in full packages, still
we can have this wrapper with a little overhead (the alternative is to move
specific methods into types of their own, but I'm not sure how it's going to
be accepted user-side).
Notice that int64 types are used for gas per block or registration price
because the price has to fit into the system fee limitation and gas per block
value can't be more than 10 GAS. We use int64 for votes as well in other types
since NEO is limited to 100M.
See neo-project/neo#2390. Can't see it there? No wonder, that's why we have
this bug for a year and a half. Not critical, we don't care about versions,
but _very_ annoying.
Saving into a file can't be successful without signAndPush flag (wallet
present). This situation can't happen in CLI invocations since
testinvokefunction doesn't have `--out` flag, but still it's a logic
error. Everything else can be simplified a bit taking that into account.
Some commands don't accept arguments, but users try giving them and don't
notice a mistake. It's a bit more user-friendly to tell the user that there is
something wrong with the way he tries to use the command.
It has a stub for SIGHUP, but doesn't have anything for USR1 and USR2:
Error: cli\server\server.go:520:31: undefined: syscall.SIGUSR1
Error: cli\server\server.go:521:31: undefined: syscall.SIGUSR2
Error: cli\server\server.go:565:17: undefined: syscall.SIGUSR1
Error: cli\server\server.go:608:17: undefined: syscall.SIGUSR2
Which allows to enable/disable the service, change nodes, keys and other
settings. Unfortunately, atomic.Value doesn't allow Store(nil), so we have to
store a pointer there that can point to nil interface.
