Make the include guards consistent by renaming them systematically according to the naming conventions below The public header files (in the 'include/openssl' directory) are not changed in 1.1.1, because it is a stable release. For the private header files files, the guard names try to match the path specified in the include directives, with all letters converted to upper case and '/' and '.' replaced by '_'. An extra 'OSSL_' is added as prefix. Reviewed-by: Richard Levitte <levitte@openssl.org> (Merged from https://github.com/openssl/openssl/pull/9681)
