* Replace the previously stringshared pointer with a new content.
*
* The string pointed by @a p_str should be previously stringshared or
* @c NULL and it will be eina_stringshare_del(). The new string will
* be eina_stringshare_add() and then assigned to @c *p_str.
*
* @param p_str pointer to the stringhare to be replaced. Must not be
* @c NULL, but @c *p_str may be @c NULL as it is a valid
* stringshare handle.
* @param news new string to be stringshared, may be @c NULL.
*
* @return #EINA_TRUE if the strings were different and thus replaced,
* #EINA_FALSE if the strings were the same after shared.
