ecc: Allow the name "q@eddsa" to get/set the public key.
* cipher/ecc-curves.c (_gcry_ecc_get_mpi): Support "q@eddsa".
(_gcry_ecc_set_mpi): Support "q".
* cipher/ecc.c (eddsa_encodepoint): Rename to ...
(_gcry_ecc_eddsa_encodepoint): this and make global. Remove arg
MINLEN and take from context.
(eddsa_decodepoint): Rename to
(_gcry_ecc_eddsa_decodepoint): this and make global. Remove arg LEN
and take from context.
(sign_eddsa, verify_eddsa): Take B from context.
(ecc_sign, ecc_verify): Add hack to set DIALECT.
(_gcry_pk_ecc_get_sexp): Use _gcry_ecc_compute_public. Handle EdDSA.
* src/ec-context.h (mpi_ec_ctx_s): Add field NBITS.
* mpi/ec.c (ec_p_init): Init NBITS.
* tests/t-mpi-point.c (test_curve): Add Ed25519.
(sample_ed25519_q): New.
(context_param): Check new sample key.
(hex2buffer, hex2mpiopa): New.
(cmp_mpihex): Take care of opaque MPIs.
