Tag profiles and abstractions with abi information.
Tagging abstractions is not strictly necessary but allows the parser
to detect when their is a mismatch and that policy will need an
update for abi.
We do not currently tag the tunables because variable declarations
are not currently affected by abi.

Local policy may want to extend or override abstractions, so add support for including local updates to them.

Move the file rule from the existing permissive system bus abstraction
into a new strict system bus abstraction.
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 system bus.

The AppArmor kernel now checks for both read and write permissions when
a process calls connect() on a UNIX domain socket.
The patch updates four abstractions that were found to be needing
changes after the change in AF_UNIX kernel mediation.

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.
