Move some of the file rules from the existing permissive session bus
abstraction into a new strict session bus abstraction. Leave the
dbus-launch rule in the permissive profile since not all applications
will need it.
The strict abstraction only allows for calling the Hello, AddMatch,
RemoveMatch, GetNameOwner, NameHasOwner, and StartServiceByName methods
that are exported by the D-Bus daemon.
The permissive abstraction reuses the strict abstraction and then allows
all communications on the session bus.

Before D-Bus mediation support was added to AppArmor, the dbus and
dbus-session abstractions granted full access to the system and session
buses, respectively.
In order to continue granting full access to those buses, bus-specific
D-Bus mediation rules need to be added to the abstractions.

Johansen, use 'ix' instead of 'Pix' for dbus-launch since if someone happens to
define a profile for dbus-launch and it is loosely confined, then users of this
abstraction could end up launching a program via dbus-launch in a less confined
manner than intended. This sort of thing should not be possible via an
abstraction (and people are always free to profile using Pix if they prefer).
