A string literal `"abc"` contains a terminating `\0`, so that is 4
bytes. There is no need to write `"abc\0"` unless two terminating
`\0`s are necessary.
`std::string` objects do not internally contain a terminating `\0`, so
`std::string("abc")` creates a string with size 3 and is the same as
`std::string("abc", 3)`.
In `"\01"` the `01` part is interpreted as one number (1) and that is
the same as `"\1"` which is a string like `{1, 0}` whereas `"\0z"` is a
string like `{0, 'z', 0}`. To create a string like `{0, '1', 0}` one
must use `"\0" "1"`.
Adjust the tests accordingly.

Quick fixups and updates for v0.21.0:
- [x] handle larger BIP155 `addrv2` addresses
- [x] add Signet chain
- [x] add an additional space between the `net` and `mping` columns; add missing `tinyformat` and `algorithm` headers
- [x] s/uptime/age/ per 0xB10C suggestion, and make the column auto-adjusting variable width
- [x] display `-` for oversized mping/ping times like `1.17348e+06`, as reported by practicalswift
Edit: removed the release note commit, as this PR was not merged before the notes were moved to the wiki. It's here:
```
- A new `bitcoin-cli -netinfo` command returns a network peer connections
dashboard that displays data from the `getpeerinfo` and `getnetworkinfo` RPCs
in a human-readable format. An optional integer argument from `0` to `4` may
be passed to see various levels of detail. (#19643)

Pull request description:
As a new requirement, sqlite support should be optional. This PR aims to be only minimum/blocker changes for 0.21.
Potential follow-up PRs after this:
* Make BDB support optional
* Nicer error messages when user tries to load an unsupported wallet
* Don't compile descriptor wallet code if sqlite disabled

Pull request description:
If we already have a transaction, don't add it to recentRejects
Now, we only add a transaction to our recentRejects filter if we didn't already have it, meaning that it is added at most once, as intended.

Outbound peer logic prevents connecting to addresses that we're already
connected to, so prevent inadvertent eviction of current peers via
test-before-evict by checking this condition and marking current peer's
addresses as Good().
Co-authored-by: John Newbery <john@johnnewbery.com>
Being able to invoke Good() is important for address management (new vs tried
table, tried table eviction via test-before-evict). We mitigate potential
information leaks by not calling Connected() on these peer addresses.
- 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

Since m_check_ratio is only set once and since the CTxMemPool object is
no longer a global variable, m_check_ratio can be passed into the
constructor of CTxMemPool. Since it is only read from after
initialization, m_check_ratio can also be made a const and hence no
longer needs to be guarded by the cs mutex.
