Commit:     Zac Medico <zmedico <AT> gentoo <DOT> org>
CommitDate: Tue Nov 27 04:37:41 2012 +0000
URL:        http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git;a=commit;h=8fa262d6

Rename Package.metadata to _metadata.

The raw metadata is considered a private low-level internal. This
makes the Package class consistent with the _pkg_str class.
