ecc.c have algorithms that could be used togeter by ecdh and ecrdsa. Make it separate module. Add CRYPTO_ECC into Kconfig. EXPORT_SYMBOL and document to what seems appropriate. Move structs ecc_point and ecc_curve from ecc_curve_defs.h into ecc.h. No code changes. Signed-off-by: Vitaly Chikunov <vt@altlinux.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
