Summary: nat_bflag shall be branch-aware

Initial Comment:
As it is called a branch flag, nat_bflag shall IMO be branch_aware ;-)
Test scenario:

* REGISTER two UACs, one of them with and the other one without NAT issue
* check your location table (cflags, received)
* Place a call, log the branch flag

You will see, that if one branch has the flag set, it is also true for
the other branch. Tested with r6115.

Best regards,
Thomas Gelf

Message:
Right now I'm running r6130 - and I can no longer reproduce this
problem (and I'm also wondering how I did before - this was pro-
bably related to some other weird things ;-)).

Please close this ticket, as I'm not allowed to do so (opened it
as anonymous).

Message:
No, branch flags are fine. What I discovered was the following:

During a REGISTER request, I'm doing my NAT checks and set bflag_nat
if able to detect such an issue.

A location lookup call will then set this flag on calls for this
specific location. However, if one user is registered multiple times,
and only one of them has this flag set in location table, lookup()
applies the flag to each branch - while it should only be set on those
really having a NAT issue.

Best regards,
Thomas Gelf

Message:
Hi Thomas, you mean the branch flags are not different in each branch ?
(even if initially , each branch had a different set of branch fags? )
