reorganizing documentation in prep for more prose

On the source side, this splits the documentation into multiple .texi
files and auto-generates the @menu for all-macros.texi, sparing a
redundant edit every time a macro is added or removed.

This also reorganizes the node structure somewhat, using numbered nodes
for everything but the macros, and organizing the macros as sections in
their own chapter, rather than full-fledged chapters.

+The Autoconf Archive is a collection of more than 450 freely re-usable macros
+for @uref{http://www.gnu.org/software/autoconf,GNU Autoconf} that have been
+contributed by friendly supporters of the cause from all over the Internet.
+
+The term ``free'' means two things in this context: (1) all macros distributed
+by the Archive can be used free of charge and (2) their use imposes no
+restrictions whatsoever on the licensing of the generated @file{configure}
+script, i.e. it is possible to use those macros in @file{configure} scripts
+that are meant for non-free software.
+
+This official web site of this project is located at
+@uref{http://savannah.nongnu.org/projects/autoconf-archive/}. All available
+information concerning this project is referenced from there.
+
+If you have questions, suggestions, are any other feedback that you'd like to
+share, then please don't hesitate to contact the Archive maintainers at
+@email{autoconf-archive-maintainers@@nongnu.org}.
