in order to avoid more surprises with branch routes, here is complete list of things that i need to be able to do in branch_route:

- call functions is_local() from modules_s/domain, is_method() and append_hf() from modules_k/textops, verify_destination() from modules/peering (uses radius), add_rr_param() from modules_k/rr, fix_nated_sdp() from modules_k/nathelper, use_media_proxy() from modules_k/mediaproxy, t_on_reply() from modules/tm, allow_source_address() from modules_k/permissions

- set $var pvs

- test flags, bflags, and gflags as well as set bflags

- test $avp pvs using is_avp_set and operators

- set $du

they are come from my working k configuration. hopefully the last one is the only one that is not supported yet.
