Brian Behlendorf 325f023544 Add linux kernel device support 
This branch contains the majority of the changes required to cleanly
intergrate with Linux style special devices (/dev/zfs).  Mainly this
means dropping all the Solaris style callbacks and replacing them
with the Linux equivilants.

This patch also adds the onexit infrastructure needed to track
some minimal state between ioctls.  Under Linux it would be easy
to do this simply using the file->private_data.  But under Solaris
they apparent need to pass the file descriptor as part of the ioctl
data and then perform a lookup in the kernel.  Once again to keep
code change to a minimum I've implemented the Solaris solution.
