(cherry picked from commit b01055b90f)

* do not handle authorization from internal sources
* do not remove authorization from internal sources

* when connecting to external from internal, a 401/407 may be returned
  and we relay that info back to media server, which will issue a new request
  with authorization, and we need to pass that info to external

(cherry picked from commit 465847bd9e)

* allows setting WITH_TCP_LISTENERS and WITH_UDP_LISTENERS when WITHOUT_DEFAULT_LISTENER is defined

* ensure REMOVE_RESERVED_HEADERS is called for internal replies
* NAT_MANAGE is relocated to ensure its called with failures

(cherry picked from commit 9c7c14bf86)

* use wildcard for amqp bindings

* kazoo custom headers

adds route REMOVE_RESERVED_HEADERS
adds external configurable setting for cleaning sip headers before sending to exterrnal

* use wildcard for AUTHORIZATION_CHECK

* add KAZOO_DB_LOCATION to defs

allows overriding the locaction of db_kazoo database

* add prometheus

creates http.cfg for handling xhttp:request
decouple websockets from xhttp:request

* add flags

* remove k-cid handling from fastpickup

* rework default listeners

adds oob definitions

* add support for internal tcp proto

* use wildcard for for local request routes

* use wildcard for deferred init

* rework websocket listeners

* add trace_init_mode

and a way to ignore tracing for configured ports

* remove local request in presence

* pusher record-route

* update dispatcher next route

* allow alg selection from other routes

other routes may set alg and then call DISPATCHER_SELECT_ROUTES

* support media check with tcp proto

* classify with X-FS-Core-UUID

support for tcp without changing KZ_DISPATCHER_CLASSIFY_FLAGS

* use wildcard for custom HANDLE_REGISTER

* handle proto for proxy-path

* allow relocation of tls config

adds xavp_cfg param to tls for easier selection of tls definition

* add tcpops module

* decouple websockets

* don't create transaction for in dialog

* run custom routes

* handle ruri alias

* add newline to log

* support tcp in media associations

* allow skip nat manage by flag

* allow no force send socket  for internal listener

* use wildcard in route extensibility

* add route to external

* adds dispatcher for outbound
* adds custom for outbound

* include extra routes

* formatting

* more decoupling with wildcard routes

* move MWI_PRESENCE_BODY to route

* code readability

* fix import extra files

* allow external definition of websocket domain

#!trydef WEBSOCKET_DOMAIN "where.is.that"
the substdef will be created with that value
this avoids the creation of substdef expressions in local.cfg or other included scripts

* add log prefix settings

* dispatcher log formatting

* use trace_ignored_methods

* use modparamx for siptrace uri

* set loglevel to debug for group route

* move KZ_PERMISSIONS_CACHE from defs.cfg

* add KZ_PERMISSIONS_MAX_SUBNET

* do not reload on the same iteration as load

* log the real number of records added

* name is unique

* ip replacement only if sdp doesn't have ice candidates
* don't do ip replacement from internal by default

* ip replacement only if sdp doesan't have ice candidates
* don't do ip replacement from internal by default

* a in-dialog from internal where loose_route() fails can still be routed if we have the alias for the contact

* so that acks go to proper address

* send_reply checks if there's a ongoing transaction and will call proper function to send the reply

- Must use socket_workers instead of tcp_children for local listener so
  that the override of the tcp_children value only applies to the local
  listener

* FLAG_SESSION_PROGRESS is set when
  the media server sends a 180/183
  which is triggered after a route reply.
  if there are no endpoints to bridge
  to (dnd, faulty callflow) the return code
  from the media can be 480 if not set explicitly by
  callflow action. in that case
  we were passing it to the incoming leg
  carrier/endpoint and some carriers retry
  the call which we don't want.

initialize password variable as
variables persist in the sip process

use $vn for password which supports $null value

* append endpoint to refer if flag is set

* simpler way to trace - all

* this should NOT be static
* we should collect and auto-add new
