Style fixes.
Remove DBL_DIG, DBL_MIN, DBL_MAX and their FLT_ counterparts, they were marked for deprecation ever since SUSv1 at least. Only define ULLONG_MIN/MAX and LLONG_MAX if long long type is supported. Restore a lost comment in MI _limits.h file and remove it from sys/limits.h where it does not belong.
