Bug 331072

Description Matthias Sohn 2010-11-24 18:01:03 EST

Provide the majority of the lstat() structure up to the
Java level.  The important part about this is first that its lstat()
and not stat(), because then we read the status of a symlink itself
and not the target of the link.  The second part is being able to get
the st_mode, st_mtime and st_size fields in a single operating system
call.  If we want to be more compatibility with the C implementation
we would honor the tv_nsec for nanosecond component of the time field,
so we can get more accurate times than just milliseconds.  We might
also want to honor the st_ctime, st_dev, st_ino, st_uid and st_gid
fields that C Git stores into the index record (see DirCacheEntry's
commented out static constants).
