We are getting rid of the "zio-" prefix in all file names.  The prefix
is needed module names (so all single-file devices triggers and
buffers) but not in component files. This simplifies stuff a little
for our command lines and tab completion.

This also removes the ugly __ZIO_INTERNAL__ define we used until now

This buffer uses vmalloc and allows mmap from user space.  It started
as a copy of buf-kmalloc, so you can diff to change what is needed
to support mmap over a read/write buffer type.

zio_free_control is needed by external buffers.

zio_alloc_control will be needed by external triggers that don't rely
on zio_fire_trigger(). It will also be needed by in-kernel sources
of output data.

Testing /dev/urandom versus zzero-0-1-data (the random device)
shows this increases performance by 0.1 usecs per block. We
are now just over 0.7 usecs per block on my development PC.

This also introduces zio-core.c with generic stuff. We agree that zio-sys
will become zio-sysfs over time.
