Description:	When a SIP device tells us in an INVITE that something is REQUIRED and we do not support that SIP option, we should not accept the INVITE. This patch adds parsing of supported and required headers and denial of unacceptaple INVITEs with REQUIRE headers. This is part of larger work with SIP Transfers. We need this in order to properly handle the Replaces option between ourselves and other servers and devices. Disclaimer is on file. Comments and tests are welcome. The part where I try to copy the device properties to a SIP peer/user is not well thought of, but will be handy later on.
