Historically (i.e., OpenSSL 1.0.x), the openssl applications would
allow for empty subject attributes to be passed via the -subj argument,
e.g., `opensl req -subj '/CN=joe/O=/OU=local' ...`.  Commit
db4c08f0 applied a badly needed rewrite
to the parse_name() helper function that parses these strings, but
in the process dropped a check that would skip attributes with no
associated value.  As a result, such strings are now treated as
hard errors and the operation fails.

Restore the check to skip empty attribute values and restore
the historical behavior.

Document the behavior for empty subject attribute values in the
corresponding applications' manual pages.

It's a bit annoying, since some commands try to read a .rnd file,
and print an error message if the file does not exist.

But previously a .rnd file was created on exit, and that does no longer
happen.

Fixed by continuing in app_RAND_load_conf regardless of the error in
RAND_load_file.

If the random number generator is still not initalized on exit, the
function RAND_write_file will fail and no .rnd file would be created.

Historically SSL_CTX_set_ssl_version() has reset the cipher list
to the default.  Splitting TLS 1.3 ciphers to be tracked separately
caused a behavior change, in that TLS 1.3 cipher configuration was
preserved across calls to SSL_CTX_set_ssl_version().  To restore commensurate
behavior with the historical behavior, set the ciphersuites to the default as
well as setting the cipher list to the default.
