tempfile: fix documentation on `delete_tempfile()` 

The function has always been documented as returning 0 or -1. It is in
fact `void`. Correct that. As part of the rearrangements we lose the
mention that `delete_tempfile()` might set `errno`. Because there is
no return value, the user can't really know whether it did anyway.

* `create_tempfile()` returns an allocated tempfile on success or NULL

* `delete_tempfile()`, `rename_tempfile()`, and `close_tempfile_gently()`
