mingw: add network-wrappers for daemon

dotzen · gitster · commit 772991af40e1 · 2010-11-04T16:53:49.000-07:00
git-daemon requires some socket-functionality that is not yet
supported in the Windows-port. This patch adds said functionality,
and makes sure WSAStartup gets called by socket(), since it is the
first network-call in git-daemon.
