Jian J Wang 469293f8ee MdeModulePkg: Fix misuses of AllocateCopyPool
AllocateCopyPool(AllocationSize, *Buffer) will copy "AllocationSize" bytes of
memory from old "Buffer" to new allocated one. If "AllocationSize" is bigger
than size of "Buffer", heap memory overflow occurs during copy.

One solution is to allocate pool first then copy the necessary bytes to new
memory. Another is using ReallocatePool instead if old buffer will be freed
on spot.

Bi, Dandan 1696b221b1 MdeModulePkg/UefiHiiLib: Fix incorrect check for string length
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=681

For string opcode,when checking the valid string length,
it should exclude the Null-terminated character.
And for string in NameValue storage, need to exclude
the varname and also need to convert the Config string
length to Unicode string length.

Dandan Bi fe4a28ccbf MdeModulePkg/UefiHiiLib:Fix incorrect comparison expression
Fix the incorrect comparison between pointer and constant zero character.

https://bugzilla.tianocore.org/show_bug.cgi?id=416

V2: The pointer StringPtr points to a string returned
by ExtractConfig/ExportConfig, if it is NULL, function
InternalHiiIfrValueAction will return FALSE. So in
current usage model, the StringPtr can not be NULL before
using it, so we can add ASSERT here.

Hao Wu 16f6922709 MdeModulePkg: Refine casting expression result to bigger size
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'.
