* configure.in: Require Autoconf 2.57b to be sure

aclocal can use autom4te --language Autoconf-without-aclocal-m4.
* m4/init.m4: Likewise.  Move the AC_PREREQ and m4_pattern_allow
calls inside the AM_INIT_AUTOMAKE macro.
* m4/auxdir.m4, m4/cond.m4, m4/lex.m4, m4/regex.m4: Move
AC_PREREQ calls inside the macros.
* m4/header.m4: Remove AC_PREREQ.
