[patch] config.status builddir awareness

[Lars J. Aas]

  Hi,

Here's the Autoconf patch for config.status builddir awareness,
and some minor textfile updates.  The acgeneral.m4 part depends on
my previous patch having been applied and massaged so there are
no quotes around $f in the case/esac.

   The same holds for configuration headers and links.
   You can instantiate unknown files and headers:
     ./config.status --header foo.h:foo.h.in --file bar:baz
+  You can concatenate multiple input files into the output file:
+    ./config.status --header foo.h:foo.h.in:foo2.h.in
+  You can also take input from stdin and output to stdout
+  by using the '-' filename convention.
+  Source files can now also be specified with absolute (/)
+  and builddir-relative (./) paths.
+  Files can be targeted for multiple directory levels that don't
+  exist yet - the one-level limit is removed.
