David Benjamin 7cdab4ac84 Make OBJ_NAME_do_all more OpenSSL-compatible.
OBJ_NAME in OpenSSL has an 'alias' field which some code consumes. We never
report anything OpenSSL considers an alias, so just leave it zero. It also has
a 'data' field which, confusingly, is a pointer to the EVP_CIPHER or EVP_MD
despite being a char pointer.

See calls to and implementation of OBJ_NAME_add in OpenSSL for comparison.
