Modern Ubuntu isn't shipping with this library installed by default.

Closes#33432.
Github-Pull: #33434

This causes IPC binaries (bitcoin-node, bitcoin-gui) to be included
in releases.
The effect on CI is that this causes more depends builds to build IPC
binaries, but still the only build running functional tests with them
is the i686_multiprocess one.
Except for Windows.
Starting with version 13.x, the mingw headers will define the value of
NTDDI_VERSION, based on the value of _WIN32_WINNT, if that version is <
Windows 10. Given that libevent was undefining our _WIN32_WINNT, and
redefining it to a value < Windows 10 (0x0501), NTDDI_VERSION was also
being defined to that value, leading to functions not being exposed in
the mingw-w64 headers; see here:
9c2668ef77/mingw-w64-headers/include/iphlpapi.h (L36-L41).
Imports a commit from usptream (a14ff91254f40cf36e0fee199e26fb11260fab49).
Fixes#32707.

This has a few advantages over the old method of simply copying headers:
- Installs proper cmake files which can be picked up by our buildsystem
- Only installs necessary headers, not all of boost

d7c37906e7 build: patch cmake min version on freetype (josibake)
Pull request description:
## Problem
While doing a depends build with CMake 4.0.1, I got the following error:
```
Extracting freetype...
/root/bitcoin/depends/sources/freetype-2.11.0.tar.xz: OK
Preprocessing freetype...
Configuring freetype...
CMake Error at CMakeLists.txt:100 (cmake_minimum_required):
Compatibility with CMake < 3.5 has been removed from CMake.
Update the VERSION argument <min> value. Or, use the <min>...<max> syntax
to tell CMake that the project requires at least <min> but has been updated
to work with policies introduced by <max> or earlier.
Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.
-- Configuring incomplete, errors occurred!
make: *** [funcs.mk:343: /root/bitcoin/depends/x86_64-pc-linux-gnu/.freetype_stamp_configured] Error 1
make: Leaving directory '/root/bitcoin/depends'
```
.. which led me to https://cmake.org/cmake/help/latest/release/4.0.html#deprecated-and-removed-features, which states compatibility with CMake versions less than 3.5 has been removed in 4.0.
## Fix
Based on the suggestion from the error message (and from reading the CMake docs), I added `-DCMAKE_POLICY_VERSION_MINIMUM=3.22`. I picked `3.22` (as opposed to 3.5) since that is the minimum version of CMake we specify in `doc/dependencies.md`. Would be nice if there was a way to pipe the min version in as a variable (since presumably we'd want to update this to be in lock step with the minimum CMake version of the whole project), but I couldn't think of a simple way to do this. Open to suggestions on a more robust way to do this if this is deemed too brittle.

With newly introduced libmultiprocess subtree, there's no need for depends
system to download and track changes to the upstream repository.
Note that adding the libmultiprocess subtree does not allow dropping
libmultiprocess packages from the depends build, because libmultiprocess
includes a code generation tool called mpgen, and in cross-compiled builds,
bitcoin core's cmake build system doesn't have access to a native toolchain and
can't build mpgen itself, so the depends system (or the native environment if
not using depends) needs to supply it.
From the GNU make 3.82 release announcement:
* The 'define' make directive now allows a variable assignment operator
after the variable name, to allow for simple, conditional, or appending
multi-line variable assignment.
macOS ships with 3.81. This caused the multiprocess config options
to be ignored.

f89f16846e depends: Fix compiling `libevent` package on NetBSD (Hennadii Stepanov)
Pull request description:
Libevent [introduced](https://github.com/libevent/libevent/pull/909) the [`typeof`](https://gcc.gnu.org/onlinedocs/gcc/Typeof.html) C language extension in the NetBSD-specific code, which was pulled into our depends in https://github.com/bitcoin/bitcoin/pull/21991.
However, GCC [states](https://gcc.gnu.org/onlinedocs/gcc/Alternate-Keywords.html):

Due to our use of b042c4f053/depends/hosts/netbsd.mk (L1)
the `typeof` keyword is disabled, resulting in a compilation error:

The `-ffile-prefix-map` compiler option implicitly enables
`-fprofile-prefix-map` in GCC or `-fcoverage-prefix-map` in Clang, which
can cause issues with coverage builds.
This change ensures that only the options necessary for build
reproducibility are applied.
The `libevent` package defaults to the "Release" build type, which
overrides our per-build-type optimization flags with `-O3`.
To prevent this behavior, set `CMAKE_BUILD_TYPE` to "None", consistent
with how other packages are handled.

Pull request description:
This PR removes UPnP IGD support and drops our [miniupnp](https://github.com/miniupnp/miniupnp) dependency.
Miniupnpc is a C library (somewhat) maintained by a single person which had several vulnerabilities in the past (a couple dozens are listed [here](https://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=miniupnp)), some of which directly affected our software ([RCE in 2015](https://bitcoincore.org/en/2024/07/03/disclose_upnp_rce/), [OOM in 2020](https://bitcoincore.org/en/2024/07/31/disclose-upnp-oom/)).
The main purpose of this functionality is to have more (non-data-center) reachable nodes on the network. For a non-technical user running Bitcoin Core at home, the software would automatically open a port on their router to receive incoming connections. This way, users not able to manually open a port on their router would still provide the network with more resources and enhance its diversity.
However, due to past vulnerabilities (and a worry about unknown future ones) in miniupnpc this feature was disabled by default in https://github.com/bitcoin/bitcoin/pull/6795. Having it disabled by default kills (most of?) the purpose of having this functionality in the first place: someone technical enough to understand the `-upnp` startup option or the "enable UPnP" setting is most likely able to open a port on his box in the first place.
In addition, laanwj implemented PCP with a NAT-PMP fallback directly in Bitcoin Core in https://github.com/bitcoin/bitcoin/pull/30043. If we ever want to re-enable automatic NAT traversal by default in Bitcoin Core, this is the best option (and in my opinion the only sane one). The NAT-PMP fallback makes it so compatibility shouldn't be (much of) an issue.
On balance, i believe that keeping this functionality and this barely maintained C dependency has higher costs than benefits. Therefore i propose that we get rid of it.
