Pull request description:

  This PR is a follow-up to #34256. It extends functional test support to illumos-based OSes and fixes several related issues on the *BSDs.

  Changes:
  - Make `lsof` an optional functional test dependency via a new `skip_if_no_lsof` helper, consistent with other optional test deps.
  - Strip the CIDR prefix length from NetBSD `ifconfig` output (no-op on other platforms).
  - Suppress spurious `lsof` warnings on NetBSD.
  - Drop OpenBSD from the platforms supported by `get_bind_addrs`.
  - Document the `lsof` Test Suite Dependency for FreeBSD and NetBSD.
  - Add support for `get_bind_addrs` and `feature_bind_extra` on illumos.

# FreeBSD Build Guide
Bitcoin Core is supported on all [supported FreeBSD releases](https://www.freebsd.org/security/#sup).
This guide describes how to build bitcoind, command-line utilities, and GUI on the most recent production release.
## Preparation
### 1. Install Required Dependencies
Run the following as root to install the base dependencies for building.
```bash
pkg install boost-libs cmake git
```
SQLite is required for the wallet:
```bash
pkg install sqlite3
```
To build Bitcoin Core without the wallet, use `-DENABLE_WALLET=OFF`.
Cap'n Proto is needed for IPC functionality (see [multiprocess.md](multiprocess.md)):
```bash
pkg install capnproto
```
Compile with `-DENABLE_IPC=OFF` if you do not need IPC functionality.
See [dependencies.md](dependencies.md) for a complete overview.
### 2. Clone Bitcoin Repo
Now that `git` and all the required dependencies are installed, let's clone the Bitcoin Core repository to a directory. All build scripts and commands will run from this directory.
```bash
git clone https://github.com/bitcoin/bitcoin.git
```
### 3. Install Optional Dependencies
#### GUI Dependencies
###### Qt6
Bitcoin Core includes a GUI built with the cross-platform Qt Framework. To compile the GUI, we need to install
the necessary parts of Qt, the libqrencode and pass `-DBUILD_GUI=ON`. Skip if you don't intend to use the GUI.
```bash
pkg install qt6-base qt6-tools
```
###### libqrencode
The GUI will be able to encode addresses in QR codes unless this feature is explicitly disabled. To install libqrencode, run:
```bash
pkg install libqrencode
```
Otherwise, if you don't need QR encoding support, use the `-DWITH_QRENCODE=OFF` option to disable this feature in order to compile the GUI.
---
#### Notifications
###### ZeroMQ
Bitcoin Core can provide notifications via ZeroMQ. To compile ZMQ support, install the following dependency and pass `-DWITH_ZMQ=ON` when configuring.
```bash
pkg install libzmq4 pkgconf
```
#### Test Suite Dependencies
There is an included test suite that is useful for testing code changes when developing.
To run the test suite (recommended), you will need to have Python 3 installed:
```bash
pkg install python3 databases/py-sqlite3 net/py-pyzmq lsof
```
---
## Building Bitcoin Core
### 1. Configuration
There are many ways to configure Bitcoin Core, here are a few common examples:
##### Wallet and GUI:
This enables the GUI, assuming `sqlite` and `qt` are installed.
```bash
cmake -B build -DBUILD_GUI=ON
```
Run `cmake -B build -LH` to see the full list of available options.
##### No Wallet or GUI
```bash
cmake -B build -DENABLE_WALLET=OFF
```
### 2. Compile
```bash
cmake --build build # Append "-j N" for N parallel jobs.
ctest --test-dir build # Append "-j N" for N parallel tests.
```
