I have no recollection of any upstream requirement to be able to
differentiate between libraries built with or without udev support
and we intention of bumping the version number for a reason such as this.

When we do bump it, it will be because of API changes that makes the
updated library incompatible with previously-compiled and supported
versions of lvm2.  (Obviously, we will now have to remember to skip the version
"1.03" because it's been used for something else!)
