The problem is at build time.. there is no msghdr on Windows. So
either I emulate it via a squid-specific struct (which is what I'm
attempting), or the data model needs changes so that it owns a msghdr
instead of inheriting from one, so that on Linux it can be a msghdr,
on windows it can be something else..
Otherwise TypedMsgHdr will end up being a Swiss cheese of #ifndefs
_SQUID_WINDOWS_ ..
