Add build of ovsext.sln using MSBuild
This commit adds to the automake build system the full build required
by the forwarding extension solution.
It will help a lot in the future CI to check the full build of the project.
To configure the forwarding extension to be built one could use the following:
./configure CC=./build-aux/cccl LD="`which link`" LIBS="-lws2_32" \
--prefix="C:/openvswitch/usr" --localstatedir="C:/openvswitch/var" \
--sysconfdir="C:/openvswitch/etc" --with-pthread="C:/pthread" \
--with-vstudioddk="Win8.1 Release"
Documentation will be updated in another patch.
