Subject: Define NDEBUG via config.h instead of CFLAGS; do not define NDEBUG if
 '--enable-assertions' passed to configure

* configure.ac (CFLAGS): Do not add "-DNDEBUG".
* configure.ac (assertions): New AC argument.
* configure.ac (NDEBUG): New AC macro (defined only if "assertions"
AC argument is not set to "yes").
