EFI_PXE_BASE_CODE_PROTOCOL has interface to set the TTL and ToS value, but
not used by the UdpWrite() interface. The code always use a hard coded 16
for the TTL and 0 for ToS.
This patch update the UpdWrite() to use the TTL and ToS which have been set
by the SetParameters().

The DHCP4 can have only one configured child instance so we need to reset
the DHCP4 child when leaving PXE driver's LoadFile() function, otherwise the
other programs which also need to use DHCP4 (like HTTP boot) will be impacted.

PXE driver's LoadFile protocol should check the input parameter
FilePath to see whether it's a supported device path.If not,
it should return invalid parameter, do not continue PXE boot.

DHCP4 service allows only one of its children to be configured
in the active state,If the DHCP4 D.O.R.A started by IP4 auto
configuration and has not been completed, the Dhcp4 state machine
will not be in the right state for the PXE to start a new round
D.O.R.A., so we need to switch it's policy to static.

if the instance of the DHCP4 protocol driver is in the Dhcp4Bound

FUNC in the EfiPxcBcDhcp() will return EFI_ALREADY_STARTED status
which lead to EfiPxeBcDhcp FUNC not in correspondence with UEFI spec.

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.
