Subject: [PATCH] swtpm: Check header size indicator against expected size (CID
375869)
This fix addresses Coverity issue CID 375869.
Check the header size indicated in the header of the state against the
expected size and return an error code in case the header size indicator
is different. There was only one header size so far since blobheader was
introduced, so we don't need to deal with different sizes.
Without this fix a specially craft header could have cause out-of-bounds
accesses on the byte array containing the swtpm's state.

Subject: [PATCH] swtpm: Disable OpenSSL FIPS mode to avoid libtpms failures
While libtpms does not provide any means to disable FIPS-disabled crypto
algorithms from being used, work around the issue by simply disabling the
FIPS mode of OpenSSL if it is enabled. If it cannot be disabled, exit
swtpm with a failure message that it cannot be disabled. If FIPS mode
was successfully disabled, print out a message as well.
