1. add library function NetLibDetectMedia to NetLib for media detection
2. update MnpDxe to periodically poll for media status update and check for media status before packet transmit
3. update Ip4Dxe to return ModeData using Mnp->GetModeData()
4. update IScsiDxe to check for media status before try to do DHCP and session login
5. update UefiPxeBcDxe to check for media status before PXE start

1. Update NetLib to a combined NetLib support dual network stack:
1) Add Network Debug facility for IPv4 stack.
2) Extend the library APIs to support IPv6 stack:
a. NetIp6IsUnspecifiedAddr
b. NetIp6IsLinkLocalAddr
c. NetIp6IsNetEqual
d. NetLibCreateIPv6DPathNode.
e. NetIp6PseudoHeadChecksum
f. NetIp6IsValidUnicast
3) Update the structure definitions:
a. Update NET_BUF to add EFI_IP6_HEADER and EFI_UDP_HEADER
b. Add NET_IP6_PSEUDO_HDR
4) Update Ip4IsUnicast to NetIp4IsUnicast
2. Update the impacted modules to adopt the combined NetLib.
3. Clean up coding style errors in all network drivers and libraries.
