Evaluate versions for multiple projects

• Make version_get_all_rows() evaluate mutiple projects, when we want to
  get all versions provided by a group of projects. Including parent
  projects if version inheritance is enabled.

• Make version_should_show_product_version() evaluate multiple
  projects, as this conditions is needed in a context for several
  projects. Eg: filters, bug-action-group, ...

• Make print_version_option_list() evaluate multiple projects. And
  remove the functionality for including version from subprojects.

• Including subproject versions in print_version_option_list() is now
  a task for the caller, by passing the exact list of projects for which
  versions are needed. This project list is managed directly by the
  filter_api and the filter specific logic.
