The digest size check on hash algorithms is incorrect.  It's
perfectly valid for hash algorithms to have a digest length
longer than their block size.  For example crc32c has a block
size of 1 and a digest size of 4.  Rather than having it lie
about its block size, this patch fixes the checks to do what
they really should which is to bound the digest size so that
code placing the digest on the stack continue to work.

HMAC however still needs to check this as it's only defined
for such algorithms.

The name authenc(hmac(sha1-talitos),cbc(aes-talitos)) is potentially
ambiguous since it could also mean using the generic authenc template
on hmac(sha1-talitos) and cbc(aes-talitos).  In general, parentheses
should be reserved for templates that spawn algorithms.

This patches changes it to the form authenc-hmac-sha1-cbc-aes-talitos.

Patch to add checking  of DES3 test vectors using CBC mode.  FIPS-140-2
compliance mandates that any supported mode of operation must include a self
test.  This satisfies that requirement for cbc(des3_ede).  The included test
vector was generated by me using openssl.  Key/IV was generated with the
following command:

	openssl enc -des_ede_cbc -P

input and output values were generated by repeating the string "Too many
secrets" a few times over, truncating it to 128 bytes, and encrypting it with
openssl using the aformentioned key.  Tested successfully by myself
