[SR-Users] append_branch. How to disable original URI

[Daniel-Constantin Mierla]

Hello,

I added some functions and variables to make these operations easier.
The older version required to update the r-ruri branch and use
append_branch(), with keeping backup or uri branch attributes in order
to restore it.

Now you have to fill the $sbranch(attribute) variable and then use
either sbranch_push_ruri() or sbranch_append()

First function is overwriting the r-uri branch, perhaps what you are
looking for. See some examples at:

  -
http://kamailio.org/docs/modules/4.3.x/modules/pv.html#pv.f.sbranch_set_ruri

Let me know if works fine, as I didn't have time for extensive testing.

Cheers,
Daniel
