commit a0160f47fe100af4e08048edcc6ea111df38862e
Author: Daniel Rubery <drubery@chromium.org>
Date: Wed Jan 09 16:24:57 2019

Add namespace third_party_unrar, to avoid polluting global namespace

Currently we have an unrar_wrapper.h that creates aliases of the global
symbols. This CL adds namespace declarations throughout the unrar code
so that we don't create nearly as many global symbols.
