commit e1d78e123b74d37f95b4075b93202b023b4320e9
Author: Michael Meeks <michael.meeks at collabora.com>
Date: Wed Jul 15 14:07:54 2015 +0100
tdf#92764 - make configmgr write less noisy.
Re-factor the TempFile abstraction and add a trivial OStringBuffer to
avoid emitting so many system calls - for writing small fragments of
configuration XML.
