There are cases that the operands of an expression are all with rank less
than UINT64/INT64 and the result of the expression is explicitly cast to
UINT64/INT64 to fit the target size.
An example will be:
UINT32 a,b;
// a and b can be any unsigned int type with rank less than UINT64, like
// UINT8, UINT16, etc.
UINT64 c;
c = (UINT64) (a + b);
Some static code checkers may warn that the expression result might
overflow within the rank of "int" (integer promotions) and the result is
then cast to a bigger size.
The commit refines codes by the following rules:
1). When the expression is possible to overflow the range of unsigned int/
int:
c = (UINT64)a + b;
2). When the expression will not overflow within the rank of "int", remove
the explicit type casts:
c = a + b;
3). When the expression will be cast to pointer of possible greater size:
UINT32 a,b;
VOID *c;
c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b);
4). When one side of a comparison expression contains only operands with
rank less than UINT32:
UINT8 a;
UINT16 b;
UINTN c;
if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...}
For rule 4), if we remove the 'UINTN' type cast like:
if (a + b > c) {...}
The VS compiler will complain with warning C4018 (signed/unsigned
mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

The classful addressing (IP class A/B/C) has been deprecated according to
RFC4632. This patch updates the NetLib NetGetIpClass() and NetIp4IsUnicast()
accordingly.
NetGetIpClass()
The function is kept for compatibility, while the caller of this function
could only check the returned value against with IP4_ADDR_CLASSD (multicast)
or IP4_ADDR_CLASSE (reserved) now. The function has been updated to note this.
NetIp4IsUnicast()
The NetMask becomes a required parameter to check the unicast address.

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.

This patch is used to define a general function to create
DNS QName.
QName is a domain name represented as a sequence
of labels, where each label consists of a length octet
followed by that number of octets. The domain name terminates
with the zero length octet for the null label of the root.
