* Main encoding function
* Returns the grid (malloced) containing the matrix. L corner at 0,0.
* Takes suggested size in *Wptr, *Hptr, or 0,0. Fills in actual size.
* Takes barcodelen and barcode to be encoded
* Note, if *encodingptr is null, then fills with auto picked (malloced)
* encoding.
* If lenp not null, then the length of encoded data before any final unlatch
* or pad is stored.
* If maxp not null, then the max storage of this size code is stored
* If eccp not null, then the number of ecc bytes used in this size is stored
* Returns 0 on error (writes to stderr with details).
