As discussed in https://git.reviewboard.kde.org/r/117091/. Not using the
SA_RESTART flag might (in theory) cause the greeter to be aborted
(because certain syscalls may be interrupted and fail with EINTR).
SA_RESTART seems to be the BSD default and is used by "legacy" signal()
by default in glibc 2 and later as well anyway.

Instead of having the greeter read the settings of the KSLD, KSLD passes
the required values to the greeter as command line arguments. This
ensures that the greeter doesn't show a lock UI while the KSLD is still
in grace time and vice versa.
Two command line options are added:
--graceTime <milliseconds>
--nolock
The option --graceTime starts the timer to show the lock ui on timeout.
The option --nolock is for the case that the KSLD never locks the
screen.

Currently the screen locker just kills the greeter (kscreenlocker_greet)
when the screen is unlocked by the user during the grace time.
But apparently this can leave behind running screensaver processes
launched by the greeter, see the bug report.
This patch changes this to only terminate the greeter, and adds a signal
handler to the greeter to exit gracefully in this case.
The signal handler exits with return code 1, so that it is not possible
to circumvent the password input by just sending a SIGTERM. (the screen
locker restarts the greeter in case it doesn't quit with exit code 0)

case of immediateLock
If the screen locker is set to not require a password to unlock, it will
not show the password input field even when the powermanagement settings
suspend the system and are set to require a password after resume (when
it was already running at that point).
This locks people out of their system.
This patch adds a signal handler for SIGUSR1 that switches the running
greeter to immediateLock mode. The locker sends that signal to make sure
the greeter shows the password input field when necessary.
