auto_ptr deprecation warnigs

[dirk-zimoch]

Compiling this module with a reasonably recent compiler gives me lots of auto_ptr deprecation warnings.
Consider using unique_ptr for sufficiently modern C++ versions (__cplusplus >= 201103L).

@dirk-zimoch , if you tested that, then from my perspective, it is a good idea.

No, I did not test that. But that is how it is is done in EPICS base.
