modules_k/dialog: Add DLGCB_CONFIRMED_NA callback and make
DLGCB_CONFIRM fit accordingly.
- Add DLGCB_CONFIRMED_NA callback which is triggered on reception
of a 200 OK message (setup-concluding ACK message still
pending).
- Execute DGLCB_CONFIRMED on reception of a setup-concluding ACK
message.
- Extend documentation and clarify that DLGCB_REQ_WITHIN does not
fire on DLGCB_CONFIRMED. (This is for consistency reasons as BYE
requests have their own callback (DLGCB_TERMINATED) as well.
Users who wish to track both setup-concluding ACK and other
sequential requests must register for both callbacks types now.)
- Closes Flyspray issue #143.
