(cherry picked from commit 52d78cc5ebc1d4fc021cabbcb09f4efb4c6ae82d)

The BIO callback handling incorrectly wrote over the return code passed
to the callback, meaning that an incorrect result was (eventually) returned
to the caller.

BIO_s_log() is declared for everyone, so should return NULL when not
actually implemented.  Also, it had explicit platform limitations in
util/mkdef.pl that didn't correspond to what was actually in code.
While at it, a few other hard coded things that have lost their
relevance were removed.

include/openssl/ocsp.h had a few duplicate declarations.

Free memory allocated in the parent process that is not needed in the

required since we end up calling exit() soon afterwards - but to
prevent false positives we free it anyway.

(cherry picked from commit 5c39a55d04ea6e6f734b627a050b9e702788d50d)

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.
