Subject: * configure.in: check struct timespec, clock_gettime, utimensat,  
 struct stat.st_atim,   struct stat.st_atimespec,   struct stat.st_atimensec, 
  struct stat.st_mtim,   struct stat.st_mtimespec,   struct stat.st_mtimensec,
   struct stat.st_ctim,   struct stat.st_ctimespec,   struct
 stat.st_ctimensec.

* include/ruby/missing.h: provide struct timespec if not available.

* time.c: support nanosecond-resolution using struct timespec.

* include/ruby/intern.h: provide rb_time_nano_new.

* file.c (utime_internal): use utimensat if available.
  (rb_file_s_utime): refactored.
  (rb_f_test): use stat_atime, stat_mtime, stat_ctime.
  (rb_stat_cmp): check tv_nsec.
  (stat_atimespec): new function.
  (stat_atime): ditto.
  (stat_mtimespec): ditto.
  (stat_mtime): ditto.
  (stat_ctimespec): ditto.
  (stat_ctime): ditto.
  (rb_stat_atime): use stat_atime.
  (rb_file_s_atime): ditto.
  (rb_file_atime): ditto.
  (rb_stat_mtime): use stat_mtime.
  (rb_file_s_mtime): ditto.
  (rb_file_mtime): ditto.
  (rb_file_ctime): use stat_ctime.
  (rb_file_s_ctime): ditto.
  (rb_stat_ctime): ditto.

* variable.c (rb_copy_generic_ivar): clear clone's instance variables
  if obj has no instance variable.

* marshal.c (w_object): dump instance variables of generated string
  for TYPE_USERDEF, even if original object has instance variables.

* lib/time.rb (Time#xmlschema): use nsec instead of usec.
