For pointer subtraction, the result is of type "ptrdiff_t". According to
the C11 standard (Committee Draft - April 12, 2011):
"When two pointers are subtracted, both shall point to elements of the
same array object, or one past the last element of the array object; the
result is the difference of the subscripts of the two array elements. The
size of the result is implementation-defined, and its type (a signed
integer type) is ptrdiff_t defined in the <stddef.h> header. If the result
is not representable in an object of that type, the behavior is
undefined."
In our codes, there are cases that the pointer subtraction is not
performed by pointers to elements of the same array object. This might
lead to potential issues, since the behavior is undefined according to C11
standard.
Also, since the size of type "ptrdiff_t" is implementation-defined. Some
static code checkers may warn that the pointer subtraction might underflow
first and then being cast to a bigger size. For example:
UINT8 *Ptr1, *Ptr2;
UINTN PtrDiff;
...
PtrDiff = (UINTN) (Ptr1 - Ptr2);
The commit will refine the pointer subtraction expressions by casting each
pointer to UINTN first and then perform the subtraction:
PtrDiff = (UINTN) Ptr1 - (UINTN) Ptr2;

If the call to SetVariable is to delete the variable,
but the variable was not found, then we return EFI_SUCCESS
rather than EFI_NOT_FOUND.

So due the usb hot plug feature, we should always connect USB host controller according to the consolein device provided by PlatformData file before entering frontpage. This way can avoid usb device can not work in frontpage phase.

This code was used to tune performance in Edk. Due to EdkII has enhanced Ehci driver to force it to be connected before UHCI, then the same logic is not necessary.

Consplitter will not install these protocols any more.
2. added logic in Bds to check console handles in System table, if no console handle assigned. Bds module will fill these handles in system table accordingly.
3. fixed one bug before call ConsoleControl->SetMode in FrontPage.c.
