Add new overloads to trace operator new

[GoogleCodeExporter]

It would be helpful to trace where the program asks for dynamic memory. We 
could also provide some overloads that receive the line number and the file 
name where that occurs.

void* operator new(u-int size, string line number, string file name)
void* operator new(u-int size, QAlignment alignment, string line number, string 
file name)
void* operator new[](u-int size, string line number, string file name)
void* operator new[](u-int size, QAlignment alignment, string line number, 
string file name)

We could use some macros to switch between using tracing functions and normal 
functions.
