rename configure.in to configure.ac

It seems autoheader version 2.69 does not work with configure.in file,
and AM_CONFIG_HEADER macro.

aclocal: warning: autoconf input should be named 'configure.ac', not 'configure.in'
configure.in:585: warning: macro 'AM_CONFIG_HEADER' not found in library
Executing:  autoheader

autoheader: error: AC_CONFIG_HEADERS not found in configure.in
