One of reason for #460.
Now s3fs supports xattrs, but s3fs could not copy file mode by preserve mode(cp -p).
I tried to modify codes somtimes(some pattern), but could not fix this with supporting xattrs.

When run cp -p command, FUSE calls s3fs handlers.
But they did not call s3fs_chmod() functions after calling s3fs_setxattr().
(At this time, the file is always created 0600 mode.)

So I think that s3fs supports xattrs optionally by using option(ex. "use_xattr")
After I do this change, it is necessary to specify new option if you are using the encfs and ecryptfs etc.

I hope if there is another solution.
But now, I think that we discard the xattrs normally support, we should solve this "preserve" problem.

If you have another opinion and solution, please let me know.
Probabry, I will try to make new option for xattrs optionally.

Best Regards,
