Bugs: ASTERISK-22582
    https://issues.asterisk.org/jira/browse/ASTERISK-22582


Repository: Asterisk


Description
-------

Isolates code that manages struct sip_route.

* 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.
