No concurrency (#9)

* enh(ssh): auto_ptr replaced by unique_ptr

* enh(ssh): concurrency::mutex replaced by std::mutex

* enh(connector): WIP to suppress concurrency objects from clib

The goal here is to use standard ones.

* enh(concurrency): Standard library used for threads stuff

* fix(test): Failing tests disabled

* cleanup(ssh): debug functions removed.
