Zhang Lubo b61fda1129 NetworkPkg: Fix issue in dns driver when building DHCP packet.
Currently, DNS driver configure the dhcp message type to inform
when building dhcp packet to get dns info from, but it not works
with dhcp server deployed on linux system. However it works well
when changed to request type.

Jiaxin Wu eed4585ba5 NetworkPkg/DnsDxe: Fix zero StationIp configuration failure of DNSv6
According UEFI Spec, set to zero StationIp means to let the underlying
IPv6 driver choose a source address. But currently, DNSv6 always return
EFI_NO_MAPPING. The issue is caused by below bugs in DnsDxe:
* Incorrect TPL(TPL_CALLBACK) usage during UDP configuration.
* Failed to create the timer used to get IPv6 mapping
* Doesn't check the Ip6Mode.IsStarted flag.

Zhang Lubo 8aa2cdd79f NetworkPkg: Enhance the code in DNS driver.
There may be an error happens when we use the
configure function to set or change the configuration
data for the DNS6 instance, So we will free the
DnsServerList without configured to NULL. If we reset
the instance with the parameter DnsConfigData to NULL, the
DnsServerList will be freed twice.

Current implementation only check the RCODE in successful condition.
Need update the code for more error check according to RFC 1035 4.1.1

Jiaxin Wu 3093f45c44 NetworkPkg/DnsDxe: Handle CNAME type responded from the name server
v2:
* Code refine.
* For DnsCache, the minimum value of TTL is selected between CNAME and A/AAAA record.

According RFC 1034 - 3.6.2, if the query name is an alias, the name server
will include the CNAME record in the response and restart the query at the
domain name specified in the data field of the CNAME record. RFC also provides
one example server action when A query received:

Suppose a name server was processing a query with for USCISIC.ARPA, asking for
type A information, and had the following resource records:
USC-ISIC.ARPA IN CNAME C.ISI.EDU
C.ISI.EDU     IN A     10.0.0.52
Both of these RRs would be returned in the response to the type A query.

Currently, DnsDxe driver doesn't handle the CNAME type response, which will cause
any exception result. The driver need continue the packet parsing while CNAME type
record parsed. So, this patch is used to handle it correctly.

Fu Siyuan 37b680116d NetworkPkg: Check received packet size before use it.
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.
