Do the final padding check in EVP_DecryptFinal_ex in constant time to
avoid a timing leak from padding failure.

80640bf0bc Fix for EVP_PBE_alg_add(). 
In EVP_PBE_alg_add don't use the underlying NID for the cipher
as it may have a non-standard key size.

84fe686173 evp: prevent underflow in base64 decoding 
This patch resolves RT ticket #2608.

Thanks to Robert Dugal for originally spotting this, and to David
Ramos for noticing that the ball had been dropped.

e5420be6cd Make CBC decoding constant time. 
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.

CFB mode does *not* have to be a multiple of the block length and several

6c6ca18664 The "block length" for CFB mode was incorrectly coded as 1 all the time. It 
should be the number of feedback bits expressed in bytes. For CFB1 mode set
this to 1 by rounding up to the nearest multiple of 8.
