I believe these two typedefs should be merged into one.  The
'key' and 'item' arguments are referring to the same thing.

On the other hand, it may make sense to define a separate
typedef for kDummySearchRef, because it is cast to a
SecKeychainSearchRef.

There are 2 typedefs because the keys have to be uintptr_t while the type for
the item could, in theory, even be an uint16_t in this test code.
But since we decided to use uintptr_t for both keys and items, I will merge the
2 typedefs into a single typedef.
Because kDummySearchRef is cast to SecKeychainSearchRef, then it should be
declared of type SecKeychainSearchRef. Right?
