Double-quote strings that would otherwise contain M4 comments.

Besides an outdated shell startup, this could have been created

ac_pwd, and quote srcdir.

(EXTRA_DIST): Remove autoconf.in.

(autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
(ifnames): chmod -w.
* tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
executables, not bin/ executables! Otherwise all the magic needed
to find non installed files is turned off. This caused a failure
of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
as found in its environment (sent by tests/autoreconf): pointing
to bin/autom4te that could not find its files.
* tests/mktests.sh: Force the replacement of generated files, for
the sake of "mv" program that are interactive when overwriting a
-w file.

* doc/autoconf.texi (Installation Directory Variables): Update.
(Limitations of Make): Some about `Single Suffix Rules and
Separated Dependencies'.
* bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
(ifnames, autoscan, autom4te): Un-factor into several rules.
make handles suffix-rules differently from GNU make.
(SUFFIXES, .in): Remove.
(autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
Move the body of the old .in rule here.
(ifnames, autoscan, autom4te): Since we don't only depend on
configure.ac variables (such as VERSION etc.), but also on prefix
and so forth, depend on Makefile, not configure.ac.

AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.

Invoke _AS_PREPARE (not AS_PREPARE) in addition to
AS_SHELL_SANITIZE.
Use this M4sh to generate Autoconf's shell scripts.
* tests/wrapsh.as: New, precursor of wrapsh.in.
* tests/Makefile.am: Include lib/freeze.mk to get the dependencies
on Autotest and M4sh.

* bin/Makefile.am (ETAGS_SH): Don't use characters ranges.
From Paul Eggert.
* lib/Makefile.am (edit, autom4te.cfg): New.
* bin/autom4te.in (BEGIN): Simplify.
Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.
(&load_configuration): New. Use it.
