Use unique_ptr, not auto_ptr, in HLT

[wmtan]

The last use of the deprecated std::auto_ptr in the CMS framework is the "put" interface for EDProducts, which also supports std::unique:ptr. This PR changes all put calls in HLT to use std::unique_ptr instead of std::auto_ptr. Some other instances of std::auto_ptr in HLT may also have been changed to std::unique_ptr.

This pull request is fully signed and it will be integrated in one of the next CMSSW_8_1_X IBs (tests are also fine). This pull request requires discussion in the ORP meeting before it's merged. @slava77, @davidlange6, @Degano, @smuzaffar
