DESCRIPTION
DH_new() allocates and initializes a DH structure. 
DH_free() frees the DH structure and
its components. The values are erased before the memory is returned
to the system. 
RETURN VALUES
If the allocation fails, DH_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. 
DH_free() returns no value.
