<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">A bit uncommon to have the unknown between the known values.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">route_loose = 0 because a route is loose when no hops exist, and the field is zero when sip_route's are created (as part of a larger ast_calloc).
route_unknown is used when a hop is inserted to the head of sip_route->list. Maybe it would be better if I rename route_unknown to route_invalidated, document that strict/loose needs to be rechecked?</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I can see that. But I'm not fond of is_something() taking a non-const.
(Although the alternatives of an explicit sip_route_finalize() call or (worse) const-casting aren't too pretty either.)</pre>

* Move route code to sip/route.c + sip/include/route.h
* Rename functions to sip_route_*
* Replace ad-hoc list code with macro's from linkedlists.h
* Create sip_route_process_header() to processes Path and Record-Route headers (previously done with different code in build_route and build_path)
* Make sip_route uri accessor return a const
* Move struct uriparams, struct contact and contactliststruct from sip.h to reqresp_parser.h. sip/route.c uses reqresp_parser.h but not sip.h, this was a problem. These moved declares are not used outside of reqresp_parser.
* While modifying reqprep() the lack of {} caused me trouble. I added them.
* Code outside route.c treats sip_route as an opaque structure, using macro's or procedures for all access.</pre>
