Windows build: #include winsock2.h only when needed.

#include winsock2.h pulls in about 90 distinct .h files
and about 140 total .h files. 
Currently winsock2.h is (mostly unnecessarily) included
for each dissector via packet.h/wtap.h.
This patch removes #include winsock2.h from wtap.h and 
then includes winsock2.h (or windows.h) in the 
few specific places required. 
With this patch, my Windows Wireshark build takes 
about 30% less time.
