Changes for root 5.34.22

Complete list of checksum / IORules changes as required by the new
version of root. This is the squashing of all the commits we had on the
CMSSW_7_3_DEVEL_X branch.
Ok.. Anyways... Sanity checks ongoing. Will include this in the release as
they terminate. Once I understand how @slava77 wants to proceed for the
validation I'll also include the new root.
