#9675: SIMPLE: Request retried with credentials with same branch and cseq number,
ie. same transaction

--------------------+-------------------------------------------------------
 When 401 or 407 is received for a request and it's decided that the
 request should be retried with credentials, then the new request must be
 sent in a new transaction with a new branch id and cseq number.

 Otherwise the SIP proxy or server which received the request may take it
 as a re-transmission of the initial request without credentials, and
 therefore re-transmits its 401/407 response.

 Tested on 2.5.5, but inspecting current development version of simple.c
 tells me the bug still exists in process_input_message.

 Both PUBLISH, and SUBSCRIBE requests publishing current status and
 subscribing to other users status are affected by this bug. But not
 REGISTER requests, which are handled differently.
