Windows: fix mapping between POSIX and Windows socket types

MinGW at least still defines several socket structure fields with size_t
instead of socklen_t. In order to maintain the POSIX API definition in
appearance we need to cast these types to their POSIX variant regardless
of whether size_t or socklen_t is used.
