If you use "-newkey rsa" it's supposed to read the default number of bits from the
config file.  However the value isn't used to generate the key, but it does
print it's generating such a key.  The set_keygen_ctx() doesn't call
EVP_PKEY_CTX_set_rsa_keygen_bits() and you end up with the default set in
pkey_rsa_init() (1024).  Afterwards the number of bits gets read from the config
file, but nothing is done with that anymore.

We now read the config first and use the value from the config file when no size
is given.

apps/pkcs12.c accepts -password as an argument.  The document author
almost certainly meant to write "-password, -passin".

However, that is not correct, either.  Actually the code treats
-password as equivalent to -passin, EXCEPT when -export is also
specified, in which case -password as equivalent to -passout.

Remove reference to ERR_TXT_MALLOCED in the error library as that is
only used internally. Indicate that returned error data must not be
freed.

Always add a dynamically loaded ENGINE to list. Otherwise it can cause
problems when multiply loaded, especially if it adds new public key methods.
For all current engines we only want a single implementation anyway.

Use default instead of ENGINE version of digest. Without this
errors will occur if you use an ENGINE for a private key and
it doesn't implement the digest in question.

The flag SSL_OP_MSIE_SSLV2_RSA_PADDING hasn't done anything since OpenSSL
0.9.7h but deleting it will break source compatibility with any software
that references it. Restore it but #define to zero.

For DTLS we might need to retransmit messages from the previous session
so keep a copy of write context in DTLS retransmission buffers instead
of replacing it after sending CCS. CVE-2013-6450.

Original definition depended on __LONG_MAX__ that is not guaranteed to
be present. As we don't support platforms with int narrower that 32 bits
it's appropriate to make defition inconditional.

    - EC_GROUP_cmp shouldn't consider curves equal just because
      the curve name is the same. (They really *should* be the same
      in this case, but there's an EC_GROUP_set_curve_name API,
      which could be misused.)

    - EC_POINT_cmp shouldn't return 0 for ERR_R_SHOULD_NOT_HAVE_BEEN_CALLED
      or EC_R_INCOMPATIBLE_OBJECTS errors because in a cmp API, 0 indicates
      equality (not an error).
