tools: Add err.h with ERR_PTR PTR_ERR interface
Adding part of the kernel's <linux/err.h> interface:
inline void * __must_check ERR_PTR(long error);
inline long __must_check PTR_ERR(__force const void *ptr);
inline bool __must_check IS_ERR(__force const void *ptr);
It will be used to propagate error through pointers in following
patches.
