r18479: start hiding libreplace configure tests behind macros

AC_LIBREPLACE_CC_CHECKS
AC_LIBREPLACE_BROKEN_CHECKS
and
AC_LIBREPLACE_ALL_CHECKS
which calls the 2 others

I'll add some more, so that samba3/samba4 can later call
them in the wanted order and all standalone builds
use AC_LIBREPLACE_ALL_CHECKS.
