[openssl-users] [openssl-dev] Is X509_free(NULL) ok?

[Salz, Rich]

➢     I think we fixed all such cases in 1.1.0, all *_free() functions
    should handle NULL. I don't think we backported to changes to 1.0.2.
    
Yes, and we fixed the documentation.  I backported all/most of them to 1.0.2 to make cherry-picking easier.  I don’t know if I changed the docs.
