cleanup: rename all iteritems methods to items and add iteritems alias

Due to a quirk of our module importer setup on Python 3, all calls and
definitions of methods named iteritems() get rewritten at import
time. Unfortunately, this means there's not a good portable way to
access these methods from non-module-loader'ed code like our unit
tests. This change fixes that, which also unblocks test-manifest.py
from passing under Python 3.

We don't presently define any itervalues methods, or we'd need to give
those similar treatment.
