Pull request description:
This PR makes code more maintainable by leveraging `-Wswitch` compiler warnings.
Only the `RecentRequestsTableModel` is not refactored, because its `enum ColumnIndex` contains additional `NUMBER_OF_COLUMNS` value.
No behavior change.

7af25024e9563241c72797d4eeabdf660e548f53 build: compile libnatpmp with -DNATPMP_STATICLIB on Windows (fanquake)
ee35745754075d862e1855c77b20a09b260cce75 build: use newer source for libnatpmp (fanquake)
Pull request description:
The source we are currently using is from 2015. The upstream repo has
received a small number of bug fixes and improvements since then.
Including one that fixes an issue for Windows users: https://github.com/miniupnp/libnatpmp/pull/13.
The source we are currently using is the most recent "official" release,
however I don't think it's worth waiting for a new one. The maintainer
was prompted to do so in Oct 2020, then again in Jan of this year, and
no release has eventuated. Given libnatpmp is a new inclusion into our
repository, I think we should be using this newer source.
This also cleans up a few warnings we currently see in Windows depends builds:

67c59ae4793b1a5ebe0c4c542abf3c095e6a658b qt: Make warning label look clickable (Jarol Rodriguez)
Pull request description:
The warning icon on the overview page indicates that there is something important the user should know about, but a user may not be aware that they can click it because, on `master`, the warning label does not look clickable. As detailed in issue #23, the reason to make it look clickable is that it if they "had a more clickable-appearance (borders or beveled button edges) it could help users more quickly understand what they are being alerted to."
This PR removes the `flat` property from both `QPushButton`'s to make them look like a button, and therefore clickable. Furthermore, it updates the `Maximum Width` to `45` to fix the small hit-box issue outlined in issue #215.
Below are screenshots showing how the warning icon looks under `master` and this `PR`:

Pull request description:
Overall PR: #20158 (tree-wide: De-globalize ChainstateManager)
Based on:
- [x] #20750 | [Bundle 2/n] Prune g_chainman usage in mempool-related validation functions
Note to reviewers:
1. This bundle may _apparently_ introduce usage of `g_chainman` or `::Chain(state|)Active()` globals, but these are resolved later on in the overall PR. [Commits of overall PR](https://github.com/bitcoin/bitcoin/pull/20158/commits)
2. There may be seemingly obvious local references to `ChainstateManager` or other validation objects which are not being used in callers of the current function in question, this is done intentionally to **_keep each commit centered around one function/method_** to ease review and to make the overall change systematic. We don't assume anything about our callers. Rest assured that once we are considering that particular caller in later commits, we will use the obvious local references. [Commits of overall PR](https://github.com/bitcoin/bitcoin/pull/20158/commits)
3. When changing a function/method that has many callers (e.g. `LookupBlockIndex` with 55 callers), it is sometimes easier (and less error-prone) to use a scripted-diff. When doing so, there will be 3 commits in sequence so that every commit compiles like so:
1. Add `new_function`, make `old_function` a wrapper of `new_function`, divert all calls to `old_function` to `new_function` **in the local module only**
2. Scripted-diff to divert all calls to `old_function` to `new_function` **in the rest of the codebase**
3. Remove `old_function`

Pull request description:
`src/test/fuzz/socks5.cpp` is using the symbol `BasicTestingSetup`, which is defined in `src/test/util/setup_common.h`.
Currently compilation happens to succeed because the needed dependency is indirectly included. Compilation will break as soon as the indirect dependency is broken. According to the dev notes, everything that is used must be included.
Fix the issue by including the missing include.

1. check out and build this branch locally; if you need help, don't hesitate to refer to https://jonatack.github.io/articles/how-to-review-pull-requests-in-bitcoin-core#pull-down-the-code-locally or https://jonatack.github.io/articles/how-to-compile-bitcoin-core-and-run-the-tests
2. while it is compiling, look at the code changes
3. stop signet (if it is running) with `./src/bitcoin-cli -signet stop`
4. once the build is completed, run `./src/bitcoin-cli -signet -netinfo help`
5. the help should be printed even though the signet server is not running
6. near the top you should see the new warning, "This human-readable interface will change regularly and is not intended to be a stable API" as well as a bit more description about the integer argument values.
7. start signet with `./src/bitcoind -signet`
8. test the improved invalid argument error message if you run `./src/bitcoin-cli -signet -netinfo 256` or `./src/bitcoin-cli -signet -netinfo a` (valid values are from 0 to 255)
9. leave review feedback or `ACK <commit hash>` -- done 🍻

Pull request description:
Add [regression fuzz harness](https://twitter.com/kayseesee/status/1205287895923212289) for CVE-2017-18350. This fuzzing harness would have found CVE-2017-18350 within a minute of fuzzing :)
See [`doc/fuzzing.md`](https://github.com/bitcoin/bitcoin/blob/master/doc/fuzzing.md) for information on how to fuzz Bitcoin Core. Don't forget to contribute any coverage increasing inputs you find to the [Bitcoin Core fuzzing corpus repo](https://github.com/bitcoin-core/qa-assets).
Happy fuzzing :)

Pull request description:
Add I2P support by using the [I2P SAM](https://geti2p.net/en/docs/api/samv3) protocol. Unlike Tor, for incoming connections we get the I2P address of the peer (and they also receive ours when we are the connection initiator).
Two new options are added:
```
-i2psam=<ip:port>
I2P SAM proxy to reach I2P peers and accept I2P connections (default:
none)
-i2pacceptincoming
If set and -i2psam is also set then incoming I2P connections are
accepted via the SAM proxy. If this is not set but -i2psam is set
then only outgoing connections will be made to the I2P network.
Ignored if -i2psam is not set. Notice that listening for incoming
I2P connections is done through the SAM proxy, not by binding to
a local address and port (default: true)
```
# Overview of the changes
## Make `ReadBinary()` and `WriteBinary()` reusable
We would need to dump the I2P private key to a file and read it back later. Move those two functions out of `torcontrol.cpp`.
```
util: extract {Read,Write}BinaryFile() to its own files
util: fix ReadBinaryFile() returning partial contents
util: fix WriteBinaryFile() claiming success even if error occurred
```
## Split `CConnman::AcceptConnection()`
Most of `CConnman::AcceptConnection()` is agnostic of how the socket was accepted. The other part of it deals with the details of the `accept(2)` system call. Split those so that the protocol-agnostic part can be reused if we accept a socket by other means.
```
net: check for invalid socket earlier in CConnman::AcceptConnection()
net: get the bind address earlier in CConnman::AcceptConnection()
net: isolate the protocol-agnostic part of CConnman::AcceptConnection()
net: avoid unnecessary GetBindAddress() call
```
## Implement the I2P [SAM](https://geti2p.net/en/docs/api/samv3) protocol (not all of it)
Just the parts that would enable us to make outgoing and accept incoming I2P connections.
```
net: extend CNetAddr::SetSpecial() to support I2P
net: move the constant maxWait out of InterruptibleRecv()
net: dedup MSG_NOSIGNAL and MSG_DONTWAIT definitions
net: extend Sock::Wait() to report a timeout
net: extend Sock with methods for robust send & read until terminator
net: extend Sock with a method to check whether connected
net: implement the necessary parts of the I2P SAM protocol
```
## Use I2P SAM to connect to and accept connections from I2P peers
Profit from all of the preceding commits.
```
init: introduce I2P connectivity options
net: add I2P to the reachability map
net: make outgoing I2P connections from CConnman
net: accept incoming I2P connections from CConnman
net: recognize I2P from ParseNetwork() so that -onlynet=i2p works
net: Do not skip the I2P network from GetNetworkNames()
```
