Rotate ChangeLog

[Ralf Wildenhues]

Whew, this was annoying.  I wanted to finally rotate ChangeLog files.
Merging a patch to this end from maint to branch-1.11 and master is
nontrivial, however: we want the respective ChangeLog.09 files to
contain what used to be in the respective branch's ChangeLog contents,
not that of the maint branch.  I tried a few variations, including doing
the rotation separately on each branch, but that would only lead to lots
more confusion in later merges from maint.  So finally I resorted to a
rotation patch on maint, and a couple of fake merges of that to master
and branch-1.11, ensuring that ChangeLog.09 contents are as expected.

Cheers,
Ralf
