decode: add some flags for windows

decode: add some flags for windows

We are doing a static compile of libyaml, so set the
YAML_STATIC_DECLARE compile macro. Also, strdup
is only available in the common run time (CRT) as
_strdup, so use another macro for that.

We could do it in other ways if there is something
more appropriate for the yaml library. Originally I
was doing it in an #ifdef macro, but this makes it
nice and minimal and doesn't touch the yaml files
directly.

Can't test, but LGTM assuming it works.

I've added you to the goyaml team, John.
