Subject: [PATCH 00/12] Module Validation Refactor

Split out from Extended MODVERSIONS Support [1]

This series refactors module validation during loading to ensure that
everything is checked on its way in. This is intended to make the code
robust enough that we can more confidently add new pieces like extended
MODVERSIONS.
