Add some necessary infrastructure to make it possible to run
self-tests for ansi_cprng. The bits are likely very specific
to the ANSI X9.31 CPRNG in AES mode, and thus perhaps should
be named more specifically if/when we grow additional CPRNG
support...
Successfully tested against the cryptodev-2.6 tree and a
Red Hat Enterprise Linux 5.x kernel with the follow-on
patch that adds the actual test vectors.

Add an array of encryption and decryption + verification self-tests
for rfc4309(ccm(aes)).
Test vectors all come from sample FIPS CAVS files provided to
Red Hat by a testing lab. Unfortunately, all the published sample
vectors in RFC 3610 and NIST Special Publication 800-38C contain nonce
lengths that the kernel's rfc4309 implementation doesn't support, so
while using some public domain vectors would have been preferred, its
not possible at this time.

Add infrastructure to tcrypt/testmgr to support handling ccm decryption
test vectors that are expected to fail verification.

When self-testing (de)compression algorithms, make sure the actual size of
the (de)compressed output data matches the expected output size.
Otherwise, in case the actual output size would be smaller than the expected
output size, the subsequent buffer compare test would still succeed, and no
error would be reported.

This warning:
crypto/testmgr.c: In function ‘test_comp’:
crypto/testmgr.c:829: warning: ‘ret’ may be used uninitialized in this function
triggers because GCC correctly notices that in the ctcount == 0 &&
dtcount != 0 input condition case this function can return an undefined
value, if the second loop fails.
Remove the shadowed 'ret' variable from the second loop that was probably
unintended.

This patch adds a test for the requirement that all crc32c algorithms
shall store the partial result in the first four bytes of the descriptor
context.

The FIPS specification requires that should self test for any supported
crypto algorithm fail during operation in fips mode, we need to prevent
the use of any crypto functionality until such time as the system can
be re-initialized. Seems like the best way to handle that would be
to panic the system if we were in fips mode and failed a self test.
This patch implements that functionality. I've built and run it
successfully.

As it is we only test ciphers when combined with a mode. That means
users that do not invoke a mode of operations may get an untested
cipher.
This patch tests all ciphers using the ECB mode so that simple cipher
users such as ansi-cprng are also protected.

This patch moves the newly created alg_test infrastructure into
cryptomgr. This shall allow us to use it for testing at algorithm
registrations.
