afa23c46d9 Flag to disable automatic copying of contexts. 
Some functions such as EVP_VerifyFinal only finalise a copy of the passed
context in case an application wants to digest more data. Doing this when
it is not needed is inefficient and many applications don't require it.

For compatibility the default is to still finalise a copy unless the
flag EVP_MD_CTX_FLAG_FINALISE is set in which case the passed
context is finalised an *no* further data can be digested after
finalisation.

b4f0abd246 evp/e_aes_cbc_hmac_sha*.c: limit multi-block fragmentation to 1KB. 
Excessive fragmentation put additional burden (of addtional MAC
calculations) on the other size and limiting fragments it to 1KB
limits the overhead to ~6%.

compare the expected plaintext: tag comparison is done internally.

2acc020b77 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.
