This patch provides new __futimens64 explicit 64 bit function for setting access and modification time of file (by using its file descriptor). Moreover, a 32 bit version - __futimens has been refactored to internally use __futimens64. The __futimens is now supposed to be used on systems still supporting 32 bit time (__TIMESIZE != 64) - hence the necessary conversions to 64 bit struct __timespec64. When pointer to struct __timespec64 is NULL - the file access and modification time is set to the current one (by the kernel) and no conversions from struct timespec to __timespec64 are performed. The __futimens64 reuses __utimensat64_helper defined for __utimensat64. The test procedure for __futimens64 is the same as for __utimensat64 conversion patch.
