add fs.lutimes binding

[isaacs]

Seems oddly missing, since we have the f and l versions of most other fs functions.

Is it still planned in core?

I'd like to second this.

A workaround like the polyfill above ...

var fd = fs.openSync('node-utimes.js', constants.O_SYMLINK)
fs.futimesSync(fd, atime, mtime)
fs.close(fd)

... does not work on Linux because Linux doesn't have O_SYMLINK.

So unless fs.lutimes is added, there is no cross-platform way that I can see to set the times of a symlink.

Set milestone to v0.13

@indutny ... any further thoughts on this one?
