Summary: Non-configurable tempdir for child stderr

Initial Comment:
When using [exec] or [open|] without a 2> or 2>@ redirection, the child's file descriptor 2 flows into a temporary file, but the directory used is not configurable (P_tempdir, typically "/tmp"). This causes headaches to people operating in restricted environments where /tmp is not writable:

I think that the old function TclpCreateTempFile doing this should either be dropped in favour of something like TclpOpenTemporaryFile, or fixed to call the same, flexible tempdir function DefaultTempDir() (currently unix, but should be ppromoted to platform-agnostic).
