	@function SecCodeSetCallback
	For a given Code or StaticCode object, specify a block that is invoked at certain
	stages of a validation operation. The block is only invoked for validations of this
	particular object. Note that validation outcomes are cached in the API object, and
	repeated validations will not generally result in the same set of callbacks.
	Only one callback can be active for each API object. A new call to SecCodeSetCallback
	replaces the previous callback.
	
	@param code A Code or StaticCode object whose validation should be monitored.
	@param flags Optional flags. Pass kSecCSDefaultFlags for standard behavior.
	@param old A pointer to a block pointer that receives any previously registered callback.
		Pass NULL if you are not interested in any previous value.
	@param callback A block to be synchronously invoked at certain stages of API operation.
		Pass NULL to disable callbacks for this code object. The block must be available to
		be invoked, possibly repeatedly, for as long as the code object exists or it is superseded
		by another call to this API, whichever happens earlier.
		From your block, return NULL to continue normal operation. Return a CFTypeRef object of
		suitable value for the reported stage to intervene.
