Bastien Nocera d70f15b5e8 pam: Port to sd-bus
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

PAM module for fingerprint authentication
-----------------------------------------

Using:
* Modify the appropriate PAM configuration file
(/etc/pam.d/system-auth-ac on Fedora systems), and add the line:
auth        sufficient    pam_fprintd.so
before the line:
auth        sufficient    pam_unix.so ...
* You can now enroll fingerprints using fprintd-enroll. The first available
  fingerprint available will be used to log you in.

Options:
* You can add the "debug" option on the pam configuration file line above,
  this will log more information from PAM to the file specified in your
  syslog configuration (/var/log/secure by default on Fedora)

Known issues:
* pam_fprintd does not support identifying the user itself as
  that would mean having the fingerprint reader on for all the time
  the user selection is displayed, and could damage the hardware.
  It could be fixed by having gdm/login only start the PAM conversation
  when there is activity
* pam_fprintd doesn't support entering either the password or a fingerprint,
  as pam_thinkfinger does, because it's a gross hack, and could be fixed
  by having the login managers run 2 separate PAM stacks
