There were a large number of error codes that were unused (probably a copy&paste from somewhere else). Since these have never been made public we should remove then and rebuild the error codes.

2018-04-25[SM2_sign] fix double free and return valueNicola Tuveri
Currently, critical bugs prevent using SM2 signatures through the `EVP_PKEY` interface: any application that managed to satisfy the requirement of forcing SM3 as the message digest – even if this is currently not possible transparently through the `EVP_PKEY` interface and requires manually forcing the MD selection – would crash with a segmentation fault upon calling the `SM2_sign()` function. This is easily verified using the OpenSSL CLI to execute this critical code path under the right conditions: `openssl dgst -sm3 -hex -sign sm2.eckey /path/to/file/to/sign` The issue is caused by a double free at the end of `SM2_sign()` in `crypto/sm2/sm2_sign.c` in case of successful signature generation. In addition, even if the double free was not causing segfaults, the function returns the wrong return value in case of success (it would return 0 rather than 1). This patch fixes both problems.
