Update the code to use the bdi_setup_and_register() helper to
simplify the bdi integration code. The updated code now just
registers the bdi during mount and destroys it during unmount.
The only complication is that for 2.6.32 - 2.6.33 kernels the
helper wasn't available so in these cases the zfs code must
provide it. Luckily the bdi_setup_and_register() function
is trivial.

This rule does not need to be dracut specific. Automatically loading
the zfs module stack when a zfs device is detected is usually desirable.
My only concern is that this might cause trouble for large pools where
we don't want to automatically import the pool until all the disks are
available. However, we'll cross that bridge when we come to it.

This change moves the default install location for the zfs udev
rules from /etc/udev/ to /lib/udev/. The correct convention is
for rules provided by a package to be installed in /lib/udev/.
The /etc/udev/ directory is reserved for custom rules or local
overrides.
Additionally, this patch cleans up some abuse of the bindir install
location by adding a udevdir and udevruledir install directories.
This allows us to revert to the default bin install location. The
udev install directories can be set with the following new options.
--with-udevdir=DIR install udev helpers [EPREFIX/lib/udev]
--with-udevruledir=DIR install udev rules [UDEVDIR/rules.d]
