- 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).

If no new reason codes are obtained after checking a CRL exit with an
error to avoid repeatedly checking the same CRL.
This will only happen if verify errors such as invalid CRL scope are
overridden in a callback.

Fix bug introduced in PEM_X509_INFO_bio which wouldn't process RSA keys
correctly if they appeared first.

If an ASN1_INTEGER structure is allocated but not explicitly set encode
it as zero: don't generate an invalid zero length INTEGER.

This patch makes the decoding of SSLv3 and TLS CBC records constant
time. Without this, a timing side-channel can be used to build a padding
oracle and mount Vaudenay's attack.
This patch also disables the stitched AESNI+SHA mode pending a similar
fix to that code.
In order to be easy to backport, this change is implemented in ssl/,
rather than as a generic AEAD mode. In the future this should be changed
around so that HMAC isn't in ssl/, but crypto/ as FIPS expects.

This change adds CRYPTO_memcmp, which compares two vectors of bytes in
an amount of time that's independent of their contents. It also changes
several MAC compares in the code to use this over the standard memcmp,
which may leak information about the size of a matching prefix.
