SM4 is a symmetric algorithm widely used in China, and is even mandatory
in many scenarios. We need to provide these users with the ability to
encrypt files or disks using SM4-XTS, and many other algorithms that use
SM2/3/4 algorithms or their combined algorithm scenarios, these features
are demanded by many users, this patch enables to use SM4-XTS mode to
encrypt file content, and use SM4-CBC-CTS to encrypt filename.
Similar reply as [1]. That is, better say:
```
Add support for XTS and CTS mode variant of SM4 algorithm, in similar
fashion to SM2 and SM3. The former is used to encrypt file contents, while
the latter (SM4-CBC-CTS) is used to encrypt filenames.
```
Thanks.

Thanks for your reply, it is very valuable for me, I will update it in
the next patch.
Cheers,
