    Rename configure.in to configure.ac.
    
    GNU Autoconf manual states (section 3.1):
    
      Previous versions of Autoconf promoted the name configure.in, which
      is somewhat ambiguous (the tool needed to process this file is not
      described by its extension), and introduces a slight confusion with
      config.h.in and so on (for which '.in' means "to be processed by
      configure"). Using configure.ac is now preferred.
