EVP_PKEY_cmp().

large FD: it's non-blocking mode anyway

only chance for T[ed]4 to get evicted in this module is when its cache
"overlaps" with last 128 bits of key schedule.

prefetch could have been moved closer to Td4 references. Something for
later consideration...

the source.

CRYPTO_get_idptr_callback(), CRYPTO_thread_idptr() for a 'void *' type
thread ID, since the 'unsigned long' type of the existing thread ID
does not always work well.

Put ECCdraft ciphersuites back into default build (but disabled
unless specifically requested)

the BN library more generally useful.

Also, change the default ciphersuite to give some prefererence to
ciphersuites with forwared secrecy (rather than using a random order).

and allow more general RSA OIDs for ECC certs with RSA CA sig.

make sure 'mask' is initialized in ssl_cipher_get_disabled().

Also simplify code by removing some unused arguments in static functions.

the Fortezza stuff

ciphersuites in the default cipher string.
