In case of Just works provisioning,
Close the temporary dtls session after the ownership transfer.
Now, PT will use the PSK based session for ACL provisioning.

patch#6 : rebase with master
patch#8 : Fix the ownership transfer. But ACL provisioning will still fail.
patch#10 : Change to the copy CAEndPoint_t of addDevice() using memcpy
patch#12 : Resolve provisioning credential issuses.
          (missing the provisioning status intialization to the provision of
           two or more times.)
patch#14 : Resolved mem leak in sendCARequest(). Updated doOwnershipTransfer()
	   to disable anon ECDH before leaving the method.
patch#15 : Remove .gitignore which was added accidently in previous patch.
patch$16 : Remove the code that invokes the CASelectCipherSuite().
