  To: openembedded-core

* license in meta-oe was MIT, in oe-core it was GPLv2, everyone fine with this?
* add mount.blacklist to CONFFILES
* add more rules and scripts from meta-oe
* change PV to 1.0 and bump PR to provide upgrade path from meta-oe's udev-extra-rules
  including RREPLACE/RPROVIDES/RCONFLICTS trio
