RFC: Parent argument for f(::Function) variants of mktemp{,dir}

[ghost]

This makes them on par with their non-f(::Function) equivalents. Most likely this functionality should have been included in f8ccca2.

"Bonus" commit: Documentation and mention in NEWS.md, I forgot to add this to #9017.

I think the docstrings need to go into both helpdb.jl, and (at least the signatures) into the RST where you have them. Running ./julia doc/genstdlib.jl should result in copying the docstring content from helpdb into the RST.

Thank you @tkelman, observant as always. I added the information to helpdb.jl as well, but I could not get doc/genstdlib.jl to inject the RST properly. Thus I added it manually to doc/stdlib/file.rst. If anyone can spot any syntax issue in what I wrote in doc/genstdlib.jl that could confuse the script, I would be most thankful. I think I am in line with the style used for other functions with more than one method.

A gentle ping, I think this is good to go.

I'm not sure what was wrong - it may be that you need to run make clean && make before ./julia doc/genstdlib.jl works properly. The way you added it looks close enough, but when I rerun genstdlib it gets modified slightly - 8c0602e. I'll be merging that shortly.
