Upgrade to Autoconf 2.61:

- Change configure.in to use Autoconf 2.61 and update generated files. - Update build system and documentation to support now directory variables offered by Autoconf 2.61. - Replace usages of PGAC_CHECK_ALIGNOF by AC_CHECK_ALIGNOF, now available in Autoconf 2.61. - Drop our patched version of AC_C_INLINE, as Autoconf now has the change.
