[PATCH 1/6] ws2_32/tests: Add UDP broadcast tests

[Erich Hoover]

Overview:
    This patchset is intended to provide a palatable resolution to Bug
#7929 (C&C 3 network does not work).  This result is accomplished by
replacing interface-specific bind requests (on UDP datagrams only)
with a global bind and storing the interface index.  Sockets with this
option enabled then use IP_PKTINFO to set the outgoing interface and
filter incoming packets based on interface (checking against the
stored interface index from the initial bind).

Real Name:
    Erich Hoover
Description:
    The attached patch adds tests to ws2_32 for ensuring that UDP
broadcast packets are handled properly.  The intent of this patch is
to ensure that the combination of the rest of this patchset (parts 2
through 6) do not muck up Wine's existing handling of UDP broadcast
packets.
