#### Description <!-- Describe your changes in detail -->
Normally, the IMS P-CSCF should identify the clients (UEs) by the received IP address and ports on Rx. The current code is using a mix of that, plus using Contact and Via headers, with arguable potential security issues.
This patch adds a new parameter to `ims_registrar_pcscf` and `ims_qos` modules, allowing for an optional outsource of the IPsec functionality to another element, which is also in charge of checking/enforcing correct UE Via header. The existing code is allowed to work as before, with the default value of the flag being towards that.
List of functional changes: - `ims_qos` - added `trust_bottom_via` parameter -
List of indirect changes: - default I-CSCF config example contained a questionable line which adds a `+` as a prefix in Request-URI. After way too much time wasted to figure out why the Diameter LIR has bogus SIP or TEL URI values in UserName AVP, I have discovered this. Seems like someone had just tel-URIs in their network, but otherwise the blind addition of this prefix makes no sense to me. - added a `str2ushort()` macro, since code was using some dangerous casting and macros with a larger type -
List of non-functional fixes: - spelling in comments - comments at the end of line moved above the line they refer to; with just 80 columns code-formatting, commenting on the same line provides for some super weird and hard to read code, so IMHO should not be allowed (or ... much harder now... increase to 120 columns) -
