//	Resizes the space allocated for p to size n, only if this can be
//	done without moving p (i.e., only if there is adjacent space
//	available if n is greater than p's current allocated size, or n
//	is less than or equal to p's size). This may be used instead of
//	plain realloc if an alternative allocation strategy is needed
//	upon failure to expand space, for example, reallocation of a
//	buffer that must be memory-aligned or cleared. You can use
//	realloc_in_place to trigger these alternatives only when needed.
//
//	@param	rdi (p) is address of current allocation
//	@param	rsi (newsize) is number of bytes needed
//	@return	rax is result, or NULL w/ errno
//	@see	dlrealloc_in_place()
