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 is a library-like set of functions, but they are not in the kernel,
as far as I know, so let's offer them here. We will use them in the
vmalloc buffer, in place of the circular buffer we have now, and for
allocating minor device numbers.

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.

Conflicts:

	Makefile

Now that the default trigger and default buffer are includes,
the module shoud be called zio.ko. zio-core.c will be the non-sysfs
stuff currently in zio-sys.c

We introduced -DDEBUG in two makefiles by error. One error each of us.

This moves zio-dump to the tools directory.  The Makefiles are
suitable for out-of-kenrel compilation but not for in-kernel
compilation, at this point.

The flags were incorrectly passed to make, now they are not.

From this commit onwards the whole thing compiles and works (from
2.6.34 onwards). We chose to save you from the past history of
internal zio development.
