Various Winsock constants missing

[kennykerr]

Constants like SIO_UDP_CONNRESET, SIO_BSP_HANDLE, SIO_BASE_HANDLE etc. are missing.

They appear to come from mswsock.h.

Here's a starting point for ya

public const uint SIO_ACQUIRE_PORT_RESERVATION = 2550136932;
public const uint SIO_ADDRESS_LIST_CHANGE = 671088663;
public const uint SIO_ADDRESS_LIST_QUERY = 1207959574;
public const uint SIO_APPLY_TRANSPORT_SETTING = 2550136851;
public const uint SIO_ASSOCIATE_HANDLE = 2281701377;
public const uint SIO_ASSOCIATE_PORT_RESERVATION = 2550136934;
public const uint SIO_BASE_HANDLE = 1207959586;
public const uint SIO_BSP_HANDLE = 1207959579;
public const uint SIO_BSP_HANDLE_SELECT = 1207959580;
public const uint SIO_BSP_HANDLE_POLL = 1207959581;
public const uint SIO_CHK_QOS = 3690987521;
public const uint SIO_CPU_AFFINITY = 2550136853;
public const uint SIO_ENABLE_CIRCULAR_QUEUEING = 671088642;
public const uint SIO_FIND_ROUTE = 1207959555;
public const uint SIO_FLUSH = 671088644;

Stopped here https://docs.microsoft.com/en-us/windows/win32/winsock/winsock-ioctls#sio_flush-opcode-setting-v-t1 going down the page one at a time and constexp evaluating each. Ideally we'd grab the expressions and evaluate them but doesn't appear we have that capability yet.

FYI IO control codes are unsigned. For example: https://docs.microsoft.com/en-us/windows/win32/api/winsock2/nf-winsock2-wsaioctl

@kennykerr Thanks, fixed.

Need to automate the below pattern in the constant scraper and then recognize constants defined with these macros.

/*
 * WinSock 2 extension -- manifest constants for WSAIoctl()
 */
#define IOC_UNIX                      0x00000000
#define IOC_WS2                       0x08000000
#define IOC_PROTOCOL                  0x10000000
#define IOC_VENDOR                    0x18000000

#if (_WIN32_WINNT >= 0x0600)
/*
 * WSK-specific IO control codes are Winsock2 codes with the highest-order
 * 3 bits of the Vendor/AddressFamily-specific field set to 1.
 */
#define IOC_WSK                       (IOC_WS2|0x07000000)
#endif //(_WIN32_WINNT >= 0x0600)

#define _WSAIO(x,y)                   (IOC_VOID|(x)|(y))
#define _WSAIOR(x,y)                  (IOC_OUT|(x)|(y))
#define _WSAIOW(x,y)                  (IOC_IN|(x)|(y))
#define _WSAIORW(x,y)                 (IOC_INOUT|(x)|(y))

Will fix #671 as well.
