The ASN1_OBJECT allocation routines, allocate and free an
ASN1_OBJECT structure, which represents an ASN1 OBJECT IDENTIFIER.
ASN1_OBJECT_new() allocates and initializes a ASN1_OBJECT structure.
ASN1_OBJECT_free() frees up the ASN1_OBJECT structure a.
NOTES
Although ASN1_OBJECT_new() allocates a new ASN1_OBJECT structure it
is almost never used in applications. The ASN1 object utility functions
such as OBJ_nid2obj() are used instead.
RETURN VALUES
If the allocation fails, ASN1_OBJECT_new() returns NULL and sets an error
code that can be obtained by ERR_get_error(3).
Otherwise it returns a pointer to the newly allocated structure.
