Softhsm cannot be installed as an i386 executable/library and as
a x86_64 executable/library on a Fedora host. The pkcs11 test then
fails since it cannot pick up the libsofthsm.so needed for an i386
executable (swtpm_cert) on a x86_64 host. This fixes test run errors
for run_test.sh by skipping the test in case swtpm_cert returns

Whenever we encrypt the data we generate a new random IV and append a
tlv block with the IV to the byte stream. We mark the IV with different
tags depending on whether they are for the migration data or the (TPM)
data directly. All IVs are part of the HMAC and are added to it after
the data blob.
Adjust test cases that now return larger sizes of data. A constant
checksum over the data cannot be expected anymore, thus we have to remove
the verification of the checksum over the returned state (IV changes
every time).
The size of the blobs grow by 22 bytes, 6 for the tlv header, 16 bytes
for the IV (128 bit AES key).

Prepend tag-length-value (tlv) headers in front of all data being stored in
the byte stream following the header. This lets us uniquely identify plain
data (= TPM state), encrypted data (= encrytped TPM state), migration data
(which is wrapped plain or encrytped TPM state), and an HMAC block to
validate the plain data.
We keep support for version 1 for reading the data but convert them to
version 2 when writing them out. This way we loose backwards compatibility
(downgrading of swtpm is not possible), but it allows us to extend the state
in the future by adding addition blocks with tlv headers.
Version 1 of the encryption was prepending the hash on the plaintext data
then encrypting all of it. This method is not so good. In version 2 we now
use Encrypt-then-MAC (EtM) where we encrypt the data and then calculate an
HMAC on the encrypted data.
Files written by the swtpm didn't have a header before. Now they also get a
header. This means that the state written into files and the state retrieved
using the API (swtpm_ioctl --save) have the same format, but still differ
in so far as the API wraps the data in a tlv header for migration, which the
files written out as state would never get.
Adapt a couple of test cases show file sizes and hashes have changed now.

Rather than writing to files directly and having to validate the state in
those files using TPMLIB_ValidatetState(), we now use the new
TPMLIB_SetState() call to set the TPM's state blobs. The advantage of this
call is that it doesn't overwrite state files and ends up leaving state in
files that the TPM cannot use. Instead, it validates the state immediately
when the blob is set and returns an error in case the state cannot be
accepted.
We need to adapt one test case that now gets a failure earlier than before.
Before the TPM_INIT failed, now setting the encrypted blob fails because it
cannot be decrypted and thus cannot be accepted by the TPM.
