Convert to auto-generated ChangeLog files.

Rename existing ChangeLog files so they won't be distributed.
Add targets to maintMakefile to generate ChangeLog from the Git
repository.  This will require a version of gnulib be available.
Because ChangeLog is auto-generated, we have to switch our
automake mode to "foreign" or it will complain and fail.

+Starting with GNU make 4.0 we no longer keep a separate ChangeLog file in
+source control.  We use the Gnulib git-to-changelog conversion script to
+convert the Git comments into ChangeLog-style entries for release.  As a
+result, please format your Git comments carefully so they will look clean
+after conversion.  In particular, each line of your comment will have a TAB
+added before it so be sure your comment lines are not longer than 72

 Rule #1: Don't rewrite pushed history (don't use "git push --force").
