Fixes#2799
Also 2 Arc's were replaced by one server's instance.
It is needed for p2p thread management in #2778, currently there is no point where we could store thread handles and join them because thread::join
consume the caller, which is impossible in case of Arc.
* wip
* big refactor, regretting doing this now
* PeerAddr everywhere
* cleanup
* fixup server tests
* peers api working for GET, POST is still WIP
* we can now ban/unban peers by ip only (port optional)
Update the command matcher for the server command to log a more helpful
message when it's called without a subcommand.
Before:
```sh
$ target/debug/grin server
:: Some(ArgMatches { args: {}, subcommand: None, usage: Some("USAGE:\n grin server [OPTIONS] [SUBCOMMAND]") })
```
After:
```sh
$ target/debug/grin server
Subcommand required, use 'grin help server' for details
```
Unlike panic it doesn't call destructors (Drop) so all open transactions
are not closed. It's fine when LMDB file is open by the current process
only, but if another process keeps the same file open such transactions
will be considered alive until the second process exits. We usually have
one or more long-lived process (like `wallet listen`) which opens the
same wallet db as short-lived wallet commands. When a command fails it
calls process::exit and as result leaks a transaction.
This pr replaces such calls with an exit code return, which allows to call
all destructors before calling process::exit.
