7af25024e9 build: compile libnatpmp with -DNATPMP_STATICLIB on Windows (fanquake)
ee35745754 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:

67c59ae479 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`:

This adds a `-daemonwait` flag that does the same as `-daemon` except
it, from a user perspective, backgrounds the process only after
initialization is complete.
This can be useful when the process launching bitcoind wants to
guarantee that either the RPC server is running, or that initialization
failed, before continuing. The exit code indicates the initialization
result.
This replaces the use of the libc function `daemon()` by a custom
implementation which is inspired by the glibc implementation, but also
creates a pipe from the child to the parent process for communication.
An additional advantage of having our own `daemon()` implementation is
that no MACOS-specific pragmas are needed anymore to silence a
deprecation warning.

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:

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.

How to test manually: 🔬🧪📈
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 🍻

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()
```

e3e0a2432c Add benchmark to write JSON into a string (Martin Ankerl)
Pull request description:
The benchmark `BlockToJsonVerbose` only tests generating (and destroying)
the JSON data structure, but serializing into a string is also a
performance critical aspect of the RPC calls.
Extracts test setup into a `struct TestBlockAndIndex`, and uses it in
both `BlockToJsonVerbose` and `BlockToJsonVerboseWrite`.
Also, use `ankerl::nanobench::doNotOptimizeAway` to make sure the compiler
can't optimize the result of the calls away.
Here are benchmark results on my Intel i7-8700:

* `getnetworkinfo` RPC

Introduce two new options to reach the I2P network:
* `-i2psam=<ip:port>` point to the I2P SAM proxy. If this is set then
the I2P network is considered reachable and we can make outgoing
connections to I2P peers via that proxy. We listen for and accept
incoming connections from I2P peers if the below is set in addition to
`-i2psam=<ip:port>`
* `-i2pacceptincoming` if this is set together with `-i2psam=<ip:port>`
then we accept incoming I2P connections via the I2P SAM proxy.
Implement the following commands from the I2P SAM protocol:
* HELLO: needed for all of the remaining ones
* DEST GENERATE: to generate our private key and destination
* NAMING LOOKUP: to convert .i2p addresses to destinations
* SESSION CREATE: needed for STREAM CONNECT and STREAM ACCEPT
* STREAM CONNECT: to make outgoing connections
* STREAM ACCEPT: to accept incoming connections
Introduce two high level, convenience methods in the `Sock` class:
* `SendComplete()`: keep trying to send the specified data until either
successfully sent all of it, timeout or interrupted.
* `RecvUntilTerminator()`: read until a terminator is encountered (never
after it), timeout or interrupted.
These will be convenient in the I2P SAM implementation.
`SendComplete()` can also be used in the SOCKS5 implementation instead
of calling `send()` directly.
Previously `Sock::Wait()` would not have signaled to the caller whether
a timeout or one of the requested events occurred since that was not
needed by any of the callers.
Such functionality will be needed in the I2P implementation, thus extend
the `Sock::Wait()` method.
Recognize also I2P addresses in the form `base32hashofpublickey.b32.i2p`
from `CNetAddr::SetSpecial()`.
This makes `Lookup()` support them, which in turn makes it possible to
manually connect to an I2P node by using
`-proxy=i2p_socks5_proxy:port -addnode=i2p_address.b32.i2p:port`

Our local (bind) address is already saved in `CNode::addrBind` and there
is no need to re-retrieve it again with `GetBindAddress()`.
Also, for I2P connections `CNode::addrBind` would contain our I2P
address, but `GetBindAddress()` would return something like
`127.0.0.1:RANDOM_PORT`.
Isolate the second half of `CConnman::AcceptConnection()` into a new
separate method, which could be reused if we accept incoming connections
by other means than `accept()` (first half of
`CConnman::AcceptConnection()`).
Call `GetBindAddress()` earlier in `CConnman::AcceptConnection()`. That
is specific to the TCP protocol and makes the code below it reusable for
other protocols, if the caller provides `addr_bind`, retrieved by other
means.
This check is related to an `accept()` failure. So do the check earlier,
closer to the `accept()` call.
This will allow to isolate the `accept()`-specific code at the beginning
of `CConnman::AcceptConnection()` and reuse the code that follows it.
`fclose()` is flushing any buffered data to disk, so if it fails then
that could mean that the data was not completely written to disk.
Thus, check if `fclose()` succeeds and only then claim success from
`WriteBinaryFile()`.
If an error occurs and `fread()` returns `0` (nothing was read) then the
code before this patch would have returned "success" with a partially
read contents of the file.
Extract `ReadBinaryFile()` and `WriteBinaryFile()` from `torcontrol.cpp`
to its own `readwritefile.{h,cpp}` files, so that it can be reused from
other modules.
