[OE-core] [oe-core][PATCH] eudev: Add RREPLACES/RCONFLICTS/PE for udev migration

[Bryan Evenson]

Commit e5e540513665105b963262c2eaf33f197a0a36c replaced
udev with eudev on system's using sysvinit for init.
For clean upgrades, some extra variables are needed to
appropriately mark eudev as an update to udev.

 * Add RREPLACES/RCONFLICTS for udev so udev is removed on
   upgrade and the new files are replaced.
 * Commit ca2948a1d4e408bccdfcd43fc8833ea356a74bca added
   RREPLACES/RCONFLICTS for udev-utils when the udev-utils
   package was merged into udev.  Inherit this RREPLACES
   and RCONFLICTS so older systems with udev-utils will
   still upgrade cleanly.
 * The version numbering changed with eudev from a single
   version number to an x.y.z format with a lower version
   number.  The RREPLACES/RCONFLICTS takes care of upgrading
   udev to eudev, but both eudev and udev add the udev-cache
   package.  Since udev-cache can't replace/conflict with
   itself, the PE needs to be incremented for udev-cache
   to upgrade.
