old ChangeLog files

[Stefan Monnier]

A discussion on xemacs-design about the ChangeLog.N files reminded
me that I think we should eliminate them and replace them with
a single Changelog.old file.  This would make it easier to search.

Ideally this should also be merged into `ChangeLog' itself, but
CVS performs poorly with large locally-modified files, so
it's more convenient to keep a "small" ChangeLog file and move
older stuff into ChangeLog.old.

What do people think ?
