This patch updates IP4 stack to support 32bit subnet mask in PXE boot process.
When 32bit subnet mask is used, the IP4 driver couldn't use the subnet mask to determine
whether destination IP address is on-link or not, so it will always try to send all the
packets to the destination IP address directly first, if failed it will continue
to try the default gateway.

Add 2 macros inNetLib.h
#define IP4_MASK_MAX 32
#define IP6_PREFIX_MAX 128
we will use these two macros to check the max mask/prefix length,
instead of
#define IP4_MASK_NUM 33
#define IP6_PREFIX_NUM 129
which means a valid number.
This will make the code readability and maintainability.

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.
