ecc: Change algorithm for Ed25519 x recovery.
* cipher/ecc-eddsa.c (scanval): Add as temporary hack.
(_gcry_ecc_eddsa_recover_x): Use the algorithm from page 15 of the
paper. Return an error code.
(_gcry_ecc_eddsa_decodepoint): Take care of the error code.
* mpi/mpi-mul.c (gcry_mpi_mulm): Use truncated division.
