This adds write buffer and bad block support required for JFFS2 operation on NAND devices. This also adds the minor modifications necessary for RTEMS support in the Linux header stubs and in wbuf.c. Memory and NOR backed applications should experience no difference in operation since they do not expose the callbacks required for write buffer support.
