Joshua Colp a330d0867e Make sorcery details opaque and add extended fields.
Sorcery specific object information is now opaque and allocated with the object.
This means that modules do not need to be recompiled if the sorcery specific part
is changed. It also means that sorcery can store additional information on objects
and ensure it is freed or the reference count decreased when the object goes away.

To facilitate the above a generic sorcery allocator function has been added which
also ensures that allocated objects do not have a lock.

Extended fields have been added thanks to all of the above which allows specific fields
to be marked as extended, and thus simply stored as-is within the object. Type safety
is *NOT* enforced on these fields. A consumer of them has to query and ultimately perform
their own safety check. What does this mean? Extra modules can extend already defined
structures without having to modify them.

Tests have also been included to verify extended field functionality.
