Some users may want to use resource library to manage their own resources,
besides existing users that open code union() and intersection()
implementations.

Provide a generic API for wider use.

Changelog v5:
- added test cases (Greg)

Changelog v4:
- added Rb tag (Rafael)
- Cc'ed to LKML and Greg (Rafael)

Changelog v3:
- rebased on top of v5.10-rc1
- dropped upstreamed dependencies
- added Rb tag to the last patch (Mika)

Sorry, just realized I forgot to add collected tags.
Fixed in v6. Sorry for a bit of spam.
