* libblock/include/rtems/blkdev.h: Remove count and start from
rtems_blkdev_request. Add RTEMS_BLKDEV_START_BLOCK macro.
* libblock/src/bdbuf.c: Add read ahead blocks always consecutive
comment. Change count to bufnum and remove start references. Sort
the transfer list so blocks are consecutive where possible.
* libblock/src/blkdev.c, libblock/src/nvdisk.c,
libblock/src/ramdisk.c: Change count to bufnum and remove start
references.
