Improve robustness of 'make bootstrap'.
Run autogen.sh after bootstrap-clean, to avoid bzr pull issues. * INSTALL, README: Document autogen.sh. * Makefile.in (Makefile): Mark it as precious, since it's updated atomically. (MAKE_CONFIG_STATUS): New macro. (config.status, bootstrap): Use it. This causes 'make bootstrap' to run config.status with the --recheck option, which is more appropriate for a bootstrap. (bootstrap): Run autogen.sh right after cleaning. Don't worry about failures due to missing tools. * autogen.sh: Exit with status 101 when failing due to missing tools. * make-dist: Distribute autogen.sh. Fixes: debbugs:12376

+configuration code and autoconf macros.
+
+The shell script `autogen.sh' generates 'configure' and other files by
+running the GNU build tools autoconf and automake, which in turn use
+GNU m4 and Perl. If you want to use it, you will need to install
+recent versions of these build tools. This should be needed only if
+you edit files like `configure.ac' that specify Emacs's autobuild
+procedure.
The file `Makefile.in' is a template used by `configure' to create
`Makefile'.
