Add seat.d/ callout directory and guarantee we dump the database before callout invocationHEADmaster
This adds a callout directory called seat.d/ that follows the basic
session.d/ semantics but works on seats instead of sessions.
As replacement for the old session.d/ 'session_active_changed'
semantics seat.d/ knows 'seat_active_session_changed'. Which combines
the two callouts necessary for session_active_changed into one. This has
various advantages: it's not as racy, allows the suppressing of ACL
permission changes when switching between sessions of the same user,
reduces the amount of disk IO and finally is less ugly.
This patch also moves all callout invocations into the CkManager. This
has the advantage that we can guarantee to have fully dumped the CK
database before the callout.
In summary, the session.d/ directory will now get two types of callout
invocations:
session_added
session_removed
In contrast, seat.d/ gets three types:
seat_added
seat_removed
seat_active_session_changed
The 'seat_active_session_changed' callout type gets two sets of
environment variables describing the old resp. the new session that is
active. Either set can be left out if no session was active before, or
no session will be active after the switch. This is similar to the logic
behind D-Bus' NameOwnerChanged.
This patch duplicates CkSeat's 'session-removed' signal into
'session-removed-full' (and friends). Reason for that is that the signal
forwarded via D-Bus needs the session id as string while the callout
code needs the session itself as object. Since at the time of invocation
the CkSeat is no longer in the seats hashtable it is hence necessary to
pass the object in as argument to the signal handlers, which makes this
duplification necessary to not confuse dbus-glib. For a similar reason
'active-session-changed' is duplicated as well.
