	configure configure.in 

-----------------------------  Log Message  -----------------------------

Significant overhaul of configure and site configuration files.

- config.h.in is now built from acconfig.h via autoheader.
- acconfig.h/config.h.in has all the magic needed to fully enable the
  tests configure is performing.  Lots of portability added.
- Use STDC_HEADERS properly, don't recheck things that it checks for if it
  says that the headers are standard.
- If the basic C headers aren't standard, declare what we have to rather
  than trying to navigate non-portable header mazes.
- Added autoconf tests for some additional standard types.
- Added a check for INADDR_NONE.
- Removed a bunch of linkage via subst in favor of AC_DEFINE.
- config.h.in is no longer an AC_SUBST target.  Things that needed to be
  in that file are now also set with AC_DEFINE.
- clibrary.h is no longer an AC_SUBST target.
- Look for atexit() and strtoul() with configure rather than using
  host-based #defines.
- Always use sigaction() if we have it.
- Cleaned up the configure handling of syslog facilities.
- Removed autoconf substitutions that we no longer need.
- Removed autoconf tests that are no longer needed.
- Switched some autoconf defines to more standard names.
- Relocated old defines and typedefs in acconfig.h and clibrary.h to
  marked sections for later work on getting rid of them.
