* variable length messages and accepts a pointer to an extraparams object that
* allows customizing signing by passing additional arguments.
*
* Creates the same signatures as schnorrsig_sign if msglen is 32 and the
* extraparams.ndata is the same as aux_rand32.
* Equivalent to secp256k1_schnorrsig_sign32(..., aux_rand32) if msglen is 32
* and extraparams is initialized as follows:
* ```
* secp256k1_schnorrsig_extraparams extraparams = SECP256K1_SCHNORRSIG_EXTRAPARAMS_INIT;
* extraparams.ndata = (unsigned char*)aux_rand32;
* ```
*
* Returns 1 on success, 0 on failure.
* Args: ctx: pointer to a context object (not secp256k1_context_static).
