Add a Packages-Require-Authorization Release file field

This new field allows a repository to declare that access to
packages requires authorization. The current implementation will
set the pin to -32768 if no authorization has been provided in
the auth.conf(.d) files.

This implementation is suboptimal in two aspects:
(1) A repository should behave more like NotSource repositories
(2) We only have the host name for the repository, we cannot use
    paths yet.

- We can fix those after an ABI break.

The code also adds a check to acquire-item.cc to not use the
specified repository as a download source, mimicking NotSource.
