  Log Message:
  -----------
  Added enhanced support for per msg branch variables

The msg branches are the branches created prior to t_relay(), with the set of destinations where the request should be parallel forked.
Available vars:
	$msg.branch.uri[br_idx]
	$msg.branch.duri[br_idx]
	$msg.branch.path[br_idx]
	$msg.branch.q[br_idx]
	$msg.branch.flags[br_idx]
	$msg.branch.flag(name)[br_idx]
	$msg.branch.socket[br_idx]
	$msg.branch.attr(name)[br_idx]
The indexing of the branches starts from 0 where 0 is the branch corresponding to RURI. The additional branches starts from idx 1.
What is new here is the concept of named attrs attached to each branch. These attrs can be used after the branch is created, all the way to the t_relay() moment.

  [registrar] the contact attrs are now pushed back as branch attrs

The attrs are attached to the contact at save() time, as AVP, but restored at lookup() time as branch attribute - in both cases, the name (of AVP and attribute) is the same.
