* 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.
