[yann.morin.1998@free.fr:
  - do not fail on version check if aufs ext is disabled
  - check for empty version
  - squash aufs package and linux extension in one patch
  - fail if the kernel already has aufs support
  - simplify handling of version]

[Thomas:
 - Fix the apply patch logic, it was using a non-existent
   AUFS_VERSION_MAJOR variable. BR2_PACKAGE_AUFS_SERIES is used
   instead.]
