Added new APIs in sgx_uae_service.h and sgx_ukey_exchange.h to support ECDSA quote based remote attestation. The set of legacy APIs supports EPID only and the set of new APIs supports ECDSA quotes. Enhanced Edger8r with structure deep-copy feature. Fixed bugs. Signed-off-by: Li, Xun <xun.li@intel.com>
