Implement the --info option that takes a flag as an argument
and returns information about the TPM implementation. Only the
value '1' has been defined for now, which returns a line as
the following:
{"TPMSpecification":{"family":"1.2","level":2,"revision":116}}
Extend the man page.

Implement options --tpm-spec-family, --tpm-spec-revision, and

We are currently missing the Authority Key Id in the certificate used for
creating the EK cert. To get this, we create a root CA for our local CA
and use that root CA to sign the local CA's certificate. Our local
CA is now an intermediate CA and the Authority Key Id can now be copied
into the EK cert.

Only pass through the vmid parameter to the tool creating the cert
if this parameter was set. The tool creating the cert may require
it or ignore it and is supposed to be able to track certificates
for which it minted certs using this parameter.

Implement a command for setting and querying the buffer size the
TPM implementation (libtpms) is using. The setting of the
buffersize allows to reduce the size of the buffer to a size
that the interface can support so that these two sizes match
and the TPM will not produce larger responses than what the
interface can support.
Extend swtpm_ioctl with an option to set the buffersize.
Adapt the existing tests to reflect the newly supported command.
Implement a new test for getting/setting of the buffer size.

Change the startup behavior with respect to requiring an INIT command
via control channel. We change this for the socket and chardev
interfaces so that the behavior now is the same as that of the CUSE
interface.
Introduce the --flag not-need-init command line option for the socket
and chardev interfaces to allow the old behavior using this option.
Adapt some of the test cases and swtpm_setup.sh.in that now need this
command line flag.

Allow running swtpm_setup directly as tss user using the following
command lines as an example for how to do it:
mkdir /tmp/test-tss
chown tss:tss /tmp/test-tss
chmod 770 /tmp/test-tss
su -c "swtpm_setup --tpm-state /tmp/test-tss" -s /bin/sh tss
This change prevents us from requiring invocation under the root
user.

Implement support for --locality allow-set-locality option that
is primarily useful in cases when the VTPM proxy access is enabled
by file descriptor passing.
Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>
Add options for locality handling so that commands in locality
4 for example are rejected per command line parameter. This is
useful when the vTPM is used with containers.
Also implement the custom TPM/TPM2_SetLocality command to allow
the Linux vTPM proxy driver to set the locality in which subsequent
TPM commands will be executed.

--tpm-state is a parameter that is also supported by the swtpm

Add support for UnixIO and TCP control channels. Both types of
transport require that packets are sent in big endian format
and therefore some code needs to be adjusted for that. The
ioctl interface is local and in that case no endianess conversion
is done.

test the control channel.

Add an ioctl that lets an application retrieve which keys are in use by the
TPM, i.e., file encryption or migration key
Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>
The migration key ensures that TPM state blobs, when retrieved using the
ioctl for getting state blobs, are always encrypted with this key.
When the state is later on loaded back into the TPM using the ioctl
to set the state blobs, the migration key is used to decrypt them.
