Move public mediation class types and perms to apparmor.h

Now that the parser links against libapparmor, it makes sense to move
all public permission types and flags to libapparmor's apparmor.h. This
prevents duplication across header files for the parser and libapparmor.

Additionally, this patch breaks the connection between
AA_DBUS_{SEND,RECEIVE,BIND} and AA_MAY_{WRITE,READ,BIND} by using raw
values when defining the AA_DBUS_{SEND,RECEIVE,BIND} macros. This makes
sense because the two sets of permission flags are from two distinctly
different mediation types (AA_CLASS_DBUS and AA_CLASS_FILE). While it is
nice that they share some of the same values, the macros don't need to
be linked together. In other words, when you're creating a D-Bus rule,
it would be incorrect to use permission flags from the AA_CLASS_FILE
type.

The change mentioned above allows the AA_MAY_{WRITE,READ,BIND} macros
to be removed from public-facing apparmor.h header.
