/******************************************************************************
 * Function: exif_set_tag
 * Description: Inserts or modifies an Exif tag to the Exif Info object. Typical
 *              use is to call this function multiple times - to insert all the
 *              desired Exif Tags individually to the Exif Info object and
 *              then pass the info object to the Jpeg Encoder object so
 *              the inserted tags would be emitted as tags in the Exif header.
 * Input parameters:
 *   obj       - The Exif Info object where the tag would be inserted to or
 *               modified from.
 *   tag_id    - The Exif Tag ID of the tag to be inserted/modified.
 *   p_entry   - The pointer to the tag entry structure which contains the
 *               details of tag. The pointer can be set to NULL to un-do
 *               previous insertion for a certain tag.
 * Return values:
 *     JPEGERR_SUCCESS
 *     JPEGERR_ENULLPTR
 *     JPEGERR_EFAILED
 * (See jpegerr.h for description of error values.)
 * Notes: none
