Hi all,

this is a resend of a previous patchset for adding a 'sysfs'
prioritizer. This prioritizer uses the sysfs attributes
'access_state' and 'exclusive_pref_bit' to generate the
path priority.
Priority values are identical to those from the 'alua'
prioritizer.

Note: the mentioned sysfs attributes are filled in by
every device handler, but only the 'alua' handler has
enough logic to keep them up-to-date.
So use with caution for other device handlers.
