OwnVector should use unique_ptr, not auto_ptr

[wmtan]

auto_ptr is deprecated in C++, but is still used in the framework in three places. One of these is OwnVector, which also supports unique_ptr. This PR changes every user of OwnVector that uses auto_ptr to use unique_ptr instead. and removes support for auto_ptr in OwnVector. It also uses std::make_unique when appropriate.
This PR also changes a very small number of auto_ptr's to unique_ptr's unrelated to OwnVector in files that were modified anyway.
In cases where auto_ptr was passed by reference (a bad practice), the code was modified to pass unique_ptr by value in those cases where ownership is being transferred, and to pass a bare pointer (get()) in cases where ownership is not transferred,
This PR is totally technical.

@cmsbuild @davidlange6 Again, this unit test fails in the base IB and has nothing to do with this PR.
