Add the macro QSORT, a convenient wrapper for qsort(3) that infers the size of the array elements and supports the convention of initializing empty arrays with a NULL pointer, which we use in some places. Calling qsort(3) directly with a NULL pointer is undefined -- even with an element count of zero -- and allows the compiler to optimize away any following NULL checks. Using the macro avoids such surprises. Add a semantic patch as well to demonstrate the macro's usage and to automate the transformation of trivial cases.
