This pam plugin never used GDBus because it transparently uses threads
which do not work well with a lot of PAM applications. But even settling
on the "still better to use than plain dbus library" dbus-glib wasn't
without problems, as any use or initialisation of GIO sockets would
modify signal handler for signals such as SIGPIPE (see gio/gsocket.c).
Many years later, sd-bus is a more modern alternative to the bare dbus
library with a better API.
This includes:
- Removing use of gboolean, guint, g_new0() and many glib string helpers
- Simplifying debug logging
- Marking user-facing messages to be translated
The dependency list of libfprint used to be a direct copy of the
libfprint CI list. However, many of the dependencies are not needed as
only a minimal version of libfprint is built for testing purposes.
The libfprint master branch will soon contain the v2 API. So change to
use the libfprint-1-0 which will mean that the CI will continue to work.
Note that the build_stable target will need to be removed when the new
libfprint version reaches fedora rawhide.
The gettext in fprintd would be getting confused by a new file in
libfprint that looks like it should have been translated. Ignore this
file in our build.
