get_temp_dir() should be more flexible

[RoyalKnight]

Currently this function returns "/tmp/" even if there's another way to get the correct temp-path. So you should extend this function with "ini_get('upload_tmp_dir')" before you return "/tmp/" as the last way out. Of course it's possible to set "WP_TEMP_DIR" in config-file, but why don't do it the automatic way?

Setting to 2.6 as its a change which is needed, and while it does not yet have a patch, one will be along soon enough.

I'm pretty certain there's a dup of this one somewhere.

On Windows usually there is no /tmp/ dir. You should check TEMP and TMP environment variables - if they exists, use them instead of returning /tmp.

[Denis-de-Bernardy]

true, but even now that part of the function never gets used, as far as I can tell.

Punting from 2.9 but marking for early 3.0 so we don't overlook this one again. Seems like a good fix.

(In [12519]) Check upload_tmp_dir ini settings for a usable temporary path. Props Denis-de-Bernardy. fixes #6699
