upgraded autotools

[Dominik Vogt]

I have just upgraded the autotools setup to autoconf-2.53 and
automake-1.8.  This means you can no longer build the CVS sources
with older versions.

I hope this does not cause a lot of problems with the feature and
library checks, but I'd be grateful if everybody tries the new
system and reports the problems.

For the developers the most important change is that the
acconfig.h file is gone and configure.in was renamed to
configure.ac.  If there was something like this before:

  acconfig.h:

    /* some comment */
    #define HAVE_FOOBAR

  configure.in:

    if test x$have_foobar = xyes; then
      AC_DEFINE(HAVE_FOOBAR)
    fi

it becomes

  configure.ac:

    AH_TEMPLATE([HAVE_FOOBAR],[some comment])
    if test x$have_foobar = xyes; then
      AC_DEFINE(HAVE_FOOBAR)
    fi

Ciao
