Set up for the next release.
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.
Add support for updating the GNU make web pages.

Add makefile rules for updating the http://www.gnu.org/software/make
web pages, including the online GNU make manual.
