    Misc autoconf updates
    
    * Switch to autoreconf in autogen.sh
    * Rename configure.in to configure.ac
    * Use modern form of AC_INIT and AM_INIT_AUTOMAKE
    * Set "foreign" automake option to avoid creation of a default
      COPYING and INSTALL.
    * Remove AC_PATH_PROG(RM), otherwise libtool's $RM will be overwritten
      and cause the infamous "cannot remove libtoolT" warning.
    * Remove autogenerated config.h.in from version control
    * Update .gitignore
