Kevin Lawton 414e97bc32 Enhanced the repeat IO accelerations (enabled by --enable-repeat-speedups) 
to request bulk IO operations to IO devices which are bulk IO aware.
Currently, I modified only harddrv.cc to be aware.  I added some
fields to the bx_devices_c class for the IO instructions to
place requests and receive responses from the IO device emulation.
Devices except the hard drive, don't monitor these fields so they
respond as normal.  The hard drive now monitors these fields for
bulk requests, and if enabled, it memcpy()'s data straight from
the disk buffer to memory.  This eliminates numerous inp/outp calling
sequences per disk sector.

I used the fields in bx_devices_c so that I would not have to
disrupt most IO device modules.  Enhancements can be made to
other devices if they use high-bandwidth IO via in/out instructions.
