QClass value may be not equal to 1(DNS_CLASS_INET) when
GeneralLookUp query is called. So, remove QClass value check.
Moreover, the 'Identification' and 'Type' filed in Query packet
should not be changed to little endian since the packet maybe
retransmitted while there is any error happened.

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.

Multiple network protocols have a GetModeData() interface, which may

Change the return type of DnsFillinQNameForQueryIp() from (UINT8*) to
(CHAR*). This brings the function in sync with both its internal variables
and all of its call sites, fixing the following gcc build breakage:
> NetworkPkg/DnsDxe/DnsImpl.c: In function 'DnsFillinQNameForQueryIp':
> NetworkPkg/DnsDxe/DnsImpl.c:1068:3: error: pointer targets in return
> differ in signedness
> [-Werror=pointer-sign]
> return QueryName;
> ^
The code was added in git commit fcae1a99 (SVN r19579).
