Summary: b2b_logic: dlginfo structure not updated for early dialogs

Initial Comment:
The dialoginfo structure of an outgoing leg of a b2b call is not updated when a provisional reply is received (the far end tag is missing).
The dialog structure is updated only when the dialog is confirmed (call in conversation).
This prevents attended call transfer to a call in early state to complete (see bug 3338085).

The attached patch is trying to fix the problem (only for top hiding scenario).  The same logic may be applied to a call with a scenario.
The patch is performing an update of dialoginfo structure from inside the b2b_logic module as opposed to the update of dialoginfo for confirmed dialogs, which is done by a callback function from the b2b_entities.
This may or may not be the right solution and therefor I opened this bug report to discuss the issue.
I tested the patch and it works ok for top hiding scenarios.

Unfortunately I don't have time to work more on this issue.
Anca/Bogdan, which one of  you can investigate this issue?

Thanks,
Ovidiu Sas
