LU-6449 mdt: correct status and ChangeLogs for dead objects

This patch is an addon of first patch for LU-6449
(Gerrit change http://review.whamcloud.com/20991) which implements
the feature of broadcasting HSM remove requests, with no/0 archive_id
specified, to all currently registered archives.

hsm_cdt_request_completed() has been fixed to no longer only return
SUCCEED status for HSM requests on dead objects but effective status
and also to create associated ChangeLog records. This last change
has required to also change mdd/ChangeLog interface to allow to
specify a FID, and to use this way extensively.
Error case in retry-mode has also been fixed to allow layout-lock
to be released.

sanity-hsm/test_[220a,222[c,d],224a] have been added to check correct
behavior.
