Arbitrary length of packet may be received from network, including the
packets with zero payload data or malformed protocol header. So the code
much check the actually received data size before using it. For example, in
current edk2 network stack, an zero payload UDP packet may cause the
platform ASSERT in NetbufFromExt() because of the zero fragment number.
This patch update the IpIoLib and UdpIoLib to check and discard the zero
payload data packet to avoid above assert. Some other network drivers are
also updated to check the packet size to guarantee the minimum length of
protocol header is received from upper layer driver.

1. Add GLOBAL_REMOVE_IF_UNREFERENCED to all globals
2. Update NTOHL and NTOHS to be BaseLib func SwapBytes32/SwapBytes16
3. Remove duplicate NET_SWAP_SHORT (to use NTOHS instead)

2. Update Dhcp4 and Mtftp4 driver to adopt the combined UdpIo.
3. Clean up coding style problems in combined IpIoLib/NetLib. Update Tcp4 and Udp4 to adopt the changes.

1. Add new interface Ip6IsValidUnicast
2. Add new enum IP6_EXTENSION_HEADER_TYPE
3. Add new structure IP6_ICMP_* definitions
4. Update structure from EFI_UDP4_HEADER to EFI_UDP_HEADER
5. Add new macro EFI_IP6_EQUAL
IpIoLib:
1. Update the IpIoLib to a combined library for both v4 and v6 network stack
2. Fix a bug in IpIoIcmpHandler() - for IPv6 packet, the header length is variable (basic header + extension) rathar than fixed length.
The fix removes the IPv6 header fields and notify the user with the ICMPv6 packet only containing payload.
TcpDxe/UdpDxe:
1. Update to adapt the new combined IpIoLib
2. Add gEfiIp6ProtocolGuid/gEfiIp6ServiceBindingProtocolGuid to [Protocols] in INF file since the Ip6.h is included in IpIoLib and NetLib.
3. Pass the TCP4/UDP4 UEFI SCT test on NT32 platform.
