ahfail locks the screen itself instead of hooking another locker: Wayland
through ext-session-lock-v1 (gtk-session-lock), X11 through an input grab.
It authenticates against its own PAM service, /etc/pam.d/ahfail, so a
package never has to edit another package's PAM file.
One command for every platform: ahfail (lock), ahfail test (the effect
without locking) and ahfail doctor (what is missing, with the fix).
Enter is handled directly and the entry uses no input method, since the
Wayland text-input IM swallowed Return. Sprites avoid the password box
in window coordinates, and placement gets 100 tries instead of 10.
