Patch to selectively bind while still allowing broadcasts [alternative]

Ok folks, I have an alternative solution to this bug based on the old
SO_BINDTODEVICE socket option.  As we're all likely aware, SO_BINDTODEVICE
requires administrative access.  However, SO_BINDTODEVICE can also be used if
the running process has the CAP_NET_RAW capability set.  So, to use the
attached patch:
1) apply patch
2) compile and install wine
3) add the CAP_NET_RAW capability to the preloader:
sudo setcap cap_net_raw+epi `which wine-preloader`
4) run the application that requires interface-specific binding

Unfortunately, this solution will only work on Linux (unlike my other
solution).  However, I believe that Alexandre might find this solution more
palatable than my previous attempt.  If everyone affected could please review
and test the attached patch then I would greatly appreciate it.
