Re-declaration of existing `NSRange` functions and implementation of new functions to match conventions of comparable Foundation and Core Foundation types.

NS_INLINE NSRange NSRangeZero() {

Isn't that NSRange uninitialized?

@robinkunde

You're right. It should be defined as a constant instead, like CGRectZero, etc.

@harlanhaskins
typedef NSRangeZero (NSRange){0, 0}

or

typedef NSRangeZero NSRangeMake(0, 0)
