the i2p peer counts column is displayed iff the node is connected
to at least one i2p peer, so this doesn't add clutter for users
who are not running an i2p service
- add new signet chain
- update change "uptime" column name to "age" per suggestion by 0xB10C (Timo)
- add an additional digit to mping field width
- change m_networks_size from size_t to uint8_t, as size_t was a holdover
from m_networks_size being defined as size_t m_networks.size() in a draft
- order Peer struct members by decreasing memory size
After this commit, a new network may be added by changing 4 lines:
- increment the value of `m_networks_size`
- add the network name to `m_networks`
- add the network name to this line: `result += " ipv4 ipv6 onion total block-relay\n";`
- add "counts.at(i).at(<m_networks pos>)" to this line: `result += strprintf("%-5s %5i %5i %5i %5i %5i\n...`
We don't set any `Content-Type` in the client. It is more
consistent with our other JSON-RPC use to set it to `application/json`.
Note that our server doesn't enforce content types, so it doesn't make a
difference in practice. But it is fairly strange HTTP behavior to not set it.
This came up in #18950.

Pull request description:
This PR is inspired by laanwj's python script mentioned in #19405, which it turns out I ended up using every day and extending because I got hooked on using it to monitor Bitcoin peer connections.
For the full experience, run `./src/bitcoin-cli -netinfo 4`
On Linux, try it with watch `watch ./src/bitcoin-cli -netinfo 4`
Help doc
```
$ ./src/bitcoin-cli -help | grep -A3 netinfo
-netinfo
Get network peer connection information from the remote server. An
optional integer argument from 0 to 4 can be passed for different
peers listings (default: 0).

c57f03ce17 refactor: Replace const char* to std::string (Calvin Kim)
Pull request description:
Rationale: Addresses #19000
Some functions should be returning std::string instead of const char*.
This commit changes that.
Main benefits/reasoning:
1. The functions never return nullptr, so returning a string makes code at call sites easier to review (reviewers don't have to read the source code to verify that a nullptr is never returned)
2. All call sites convert to string anyway

to allow passing rpcwallet independently from the -rpcwallet user option, and to
move the logic to the top-level layer where most of the other option args are
handled.
to ConnectAndCallRPC() to be callable for individual connections.
This is needed for RPCs that need to be called and handled sequentially, rather
than alone or in a batch.
For example, when fetching the balances for each loaded wallet, -getinfo will
call RPC listwallets, and then, depending on the result, RPC getbalances.
It may be somewhat helpful to review this commit with `git show -w`.
ASLR is not currently working for the bitcoin-cli.exe binary. This is
due to it not having a .reloc section, which is stripped by default by
the mingw-w64 ld we use for gitian builds. A good summary of issues with
ld and mingw-w64 is available in this thread:
https://sourceware.org/bugzilla/show_bug.cgi?id=19011.
All other Windows binaries that we distribute (bitcoind, bitcoin-qt,
bitcoin-wallet, bitcoin-tx and test_bitcoin) do not suffer this issue,
and currently having working ASLR. This is due to them exporting
(inadvertent or not) libsecp256k1 symbols, and, as a result, the .reloc
section is not stripped by ld.
This change is a temporary workaround, also the same one described here:
https://www.kb.cert.org/vuls/id/307144/, that causes main() to be
exported. Exporting a symbol will mean that the .reloc section is not
stripped, and ASLR will function correctly.
