        * libmisc/dummy/dummy-networking.c: New.
        * libmisc/dummy/dummy.c, libmisc/Makefile.am: Move
        trhe networking configuration into a separate file so
        configuration varations do not cause conflicts.
        * score/inline/rtems/score/object.inl,
        score/include/rtems/score/object.h: Remove warnings.
        * score/inline/rtems/score/object.inl: Add _Chain_First,
        _Chain_Last, _Chain_Mext, and _Chain_Previous.
        * sapi/inline/rtems/chain.inl: Add rtems_chain_first,
        rtems_chain_last, rtems_chain_mext, and rtems_chain_previous.
        * libblock/include/rtems/diskdevs.h: Remove the bdbuf pool id and
        block_size_log2. Add media_block_size.
        * libblock/src/diskdevs.c: Remove size restrictions on block
        size. Add media block size initialisation. Remove comment to clean
        up the bdbuf cache.
        * libblock/src/blkdev.c: Remove references to
        block_size_log2. Allow any block size.
        * libblock/include/rtems/bdbuf.h, libblock/src/bdbuf.c: Remove all
        references to pools and make the cache handle demand driver
        variable buffer size allocation. Added worker threads support the
        swapout task.
        * sapi/include/confdefs.h: Updated the bdbuf configutation.
