Make the include guards consistent by renaming them systematically according to the naming conventions below For the public header files (in the 'include/openssl' directory), the guard names try to match the path specified in the include directives, with all letters converted to upper case and '/' and '.' replaced by '_'. For the private header files files, an extra 'OSSL_' is added as prefix. Reviewed-by: Richard Levitte <levitte@openssl.org> (Merged from https://github.com/openssl/openssl/pull/9333)
