PlaySound and MessageBeep flags, and the Winsock names the socket module still spelled locally, now come from host_env. Windows SOMAXCONN is the winsock2.h value 0x7fffffff, and SOL_IP / the INADDR group constants use the host values. Assisted-by: Grok

- Line 855: Export INADDR_UNSPEC_GROUP, INADDR_ALLHOSTS_GROUP, and
INADDR_MAX_LOCAL_GROUP as unsigned u32 attributes on Windows by casting their
i32 host constants before exposing them through #[pyattr], preserving their
positive Python integer values.
- Line 859: Remove MSG_ERRQUEUE and SO_ORIGINAL_DST from the Windows socket
exports in the relevant export list; keep IP_RECVERR and IPV6_RECVERR exported.

Keep the Windows INADDR attributes unsigned.
The host constants INADDR_UNSPEC_GROUP, INADDR_ALLHOSTS_GROUP, and INADDR_MAX_LOCAL_GROUP are i32. Importing them as #[pyattr] changes the previous positive u32 values to negative Python integers. For example, socket.htonl(socket.INADDR_ALLHOSTS_GROUP) can no longer accept the exported value. Define Windows u32 attributes by casting the host values before export. (raw.githubusercontent.com)

Remove unsupported Windows socket exports.
IP_RECVERR and IPV6_RECVERR are valid Winsock options and must remain exported. Windows has no recvmsg path in this module, and recv does not support MSG_ERRQUEUE. SO_ORIGINAL_DST is only a local numeric definition; Winsock does not define or document that option. Remove MSG_ERRQUEUE and SO_ORIGINAL_DST.
