The "unbound" DNS plugin was very rudimentary and is deprecated since
commit 4a2fe09853 ('man: mark [main].dns=unbound as deprecated') (Jun
2021).
It is part of dnssec-trigger tool, but the dnssec-trigger tool doesn't
actually use it. Instead it installs a dispatcher script
"/usr/lib/NetworkManager/dispatcher.d/01-dnssec-trigger".
Especially, since the plugin requires "/usr/libexec/dnssec-trigger-script",
which is provided by "dnssec-trigger" package on Fedora. At the same
time, the package provides the dispatcher script. So I don't this works
or anybody is using this.

"autotools" also prints a similar output. It's useful to know
which libraries were enabled. Because, we run unit test against
all enabled libraries, even if they are actually used.
Currently it is possible to specify a list of default settings plugins
to be used when configuration doesn't contain the main.plugins key.
We want to add a mechanism that allows to automatically load any
plugin found in the plugins directory without needing
configuration. This mechanism is useful when plugins are shipped in a
different, optional subpackage, to automatically use them.
With such mechanism, the actual list of plugins will be determined
(in order of evaluation):
1. via explicit user configuration in /etc, if any
2. via distro configuration in /usr, if any
3. using the build-time default, if any
4. looking for known plugins in /usr/lib
- add "required:false" to dependency() and find_library(),
otherwise autodetection will fail.
- rename variable "enable_readline" to "with_readline" for
consistency with autotools.
- with -Dlibreadline=auto, once we detect a library, update
"with_readline" variable to reflect the detected choice.
This will also be printed in the summary output.
This is also important for the nmcli check
`assert(with_readline != 'none', 'readline ...`.
After this change the nmcli program built with meson will have the
possibility to use libedit (BSD license) instead of libreadline
(GPLv3).
Meson configuration line:
meson configure -Dreadline=libedit -C ../nm-build/
or
meson --reconfigure -Dreadline=libedit ../nm-build/
ninja -C ../nm-build/
The new 'readline' option is set to 'auto' by default, so
the current behavior shall be preserved (and the libreadline is
used).
Two new config.h flags (always defined) have been introduced -
HAVE_EDITLINE_READLINE and HAVE_READLINE_HISTORY.
