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;

Before the "cd fs0:dir" fix, CD only prints destination directory
when the destination contains ":".
However, the "cd fs0:dir" fix changed CD to always print destination
directory.
This patch changes CD to never print destination directory.

When "fs0:dir"(drive letter without slash) is used as destination
of "cd", "cd" tries to change to "dir" in root directory of "fs0:".
It's incorrect. The correct behavior is to change to "dir" in
current directory of "fs0:"

Allows cd command to go back to the root directory when 'cd \' executed in system.
This change prevents last PathRemoveLastItem() call which truncates '\' from 'fs0:\'
in desired root path which is required to set CWD to the root directory.

In Shell spec 2.1 the return name of EFI_SHELL_PROTOCOL.GetCurDir() is defined as 'fs0:\current-dir' while in current implementation it's 'fs0:\current-dir\'.
To follow spec the patch removed the redundant '\' char.
Since it has been broken for a long time, some codes may depend on the broken behavior.
After this change 'EFI_SHELL_PROTOCOL.GetCurDir()' and 'UefiShellLib.ShellGetCurrentDir()'
will return a current directory string without tailing '\' (fs0:\current-dir), the value of Shell environment variable 'cwd' will become 'fs0:\current-dir' as well.
This patch has updated all the code in EDKII to make them depend on the new behavior.
Developers should check whether 'GetCurDir()' and 'ShellGetCurrentDir' are used in their source code.
