国密的nid定义和标准x25519的定义都是29，这个是否国密需要调整？

参考杨洋整理的GB/T 33560-2017国密算法OID列表:

This file contains the English translation of appendix 1 of GB/T 33560-2017 - the 'OIDs' defined for Chinese commercial crypto algorithms.

Seems the remaining OIDs have nothing to do with real algorithms, they define mostly the 'doc' or 'standard' paperworks, so skipped...	...

不是OID，是NID，不过我已经咨询过了，目前国密支持的版本不支持x25519，也就是说两者不会同时使用，且国密已经被国际上承认，后续的官方标准会给国密分配固定的NID值，当前NID = 29标准是分配给x25519算法的

@Whitlynn 建议参考 OpenSSL 1.1.1预览版pre5 中SM2算法 NID 的具体取值
