1. Stop UdpWrite instance upon return from EfiPxeBcUdpWrite() to avoid mass pkgs enqueue to this useless instance in Udp layer.
2. Enhance Udp timeout logic to prevent the worst case happen, and set PxeUdp instance to 50ms to avoid enqueue mass pkgs in background.

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.

[Root Cause Analysis]
The PXE offer selection in the PXE driver is splitted into two passes and the two passes are required to follow the same flow. However, in current code, there is some difference between the two.
[Solution]
make the second offer selection pass exactly match the first one.
2. Fixed one bug when allocating pool for UDP transmit packet.

Problem with PXE boot to Windows Server 2008 install. The reason is that UdpRead and UdpWrite interfaces cannot work well with the same UDP instance.
[Solution]
Use separate instances for UDP Read and UDP write in UefiPxeBC module.
[Impaction]:
UefiPxeBcDxe and Udp4Dxe module.
