Routine Description:
Similar to x86SleazeCallersAddress but gathers a variable number of return

dwStackCount - number of elements in lplpvStack
Ebp - starting Ebp if not 0, else use current stack
Return Value:
None.

Routine Description:
This is a sleazy function that reads return addresses out of the stack/

that called THE FUNCTION THAT CALLED THIS FUNCTION, and the caller of
that function. Returning the return address of the function that called
this function is not interesting to that caller (almost worthy of Sir
Humphrey Appleby isn't it?)
Assumes:
my ebp => | caller's ebp |

Arguments:
pCaller - place where we return addres of function that called
the function that called this function
pCallersCaller - place where we return caller of above
Return Value:
None.
