--
gcry_mpi_ec_p_new() was a specialized version of the more general new
gcry_mpi_ec_new(). It was added to master only a few days ago, thus
there should be no problem to remove it. A replacement can easily be
written (cf. t-mpi-point.c).
Note that gcry_mpi_ec_set_mpi and gcry_mpi_ec_set_point have not yet
been tested.
