Allow duplicate bsn+version for a given set of bundles.

- Set 'org.osgi.framework.bsnversion' to 'managed'
- Add bundle collision/event hook to handle duplicates and their
  lifecycle.
- Add unit tests for duplicate bundles.
  o Add bundle 'l1-dup' which is a duplicate of the existing 'l1',
    but returns a different value from its implemented class.
  o Add bundle 'ml-dup' that is exactly the same as 'ml'
