Remove "dbuf phys" db->db_data pointer aliases.

Use function accessors that cast db->db_data to the appropriate
"phys" type, removing the need for clients of the dmu buf user
API to keep properly typed pointer aliases to db->db_data in order
to conveniently access their data.

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/zap_leaf.c:
        In zap_leaf() and zap_leaf_byteswap, now that the pointer alias
        field l_phys has been removed, use the db_data field in an on
        stack dmu_buf_t to point to the leaf's phys data.

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/dbuf.c:
        Remove the db_user_data_ptr_ptr field from dbuf and all logic
        to maintain it.

        Modify the DMU buf user API to remove the ability to specify
        a db_data aliasing pointer (db_user_data_ptr_ptr).
