fixed bug 37893, fixed bug 37899: incorrect CU handling in concurrency and POS

  Concurrent Users management had two different problems:
   * If a backoffice session was reused in POS closing backoffice browser, a CU
     session was counted and it was not deactivated while POS session was active.
     In this situation, the session should be deactivated if CU limit has been
     reached.
   * Code for creating and checking active http sessions in context was not thread
     safe, so it was possible to get an error when checking if session was active while
     other sessions were created/destroyed in paralell. This has been fixed by
     synchronizing on active session set. Having solved previous issue this should
     not create excessive contentention as it will be executed only if: CU limit has
     been reached and there are sessions created by mobile modules exclude POS.
