Extend the TPM emulator backend device with state migration support.
The external TPM emulator 'swtpm' provides a protocol over
its control channel to retrieve its state blobs. We implement
functions for getting and setting the different state blobs.
In case the setting of the state blobs fails, we return a
negative errno code to fail the start of the VM.
Since we have an external TPM emulator, we need to make sure
that we do not migrate the state for as long as it is busy
processing a request. We need to wait for notification that
the request has completed processing.

Extend the TPM TIS interface with state migration support.
We need to synchronize with the backend thread to make sure that a command
being processed by the external TPM emulator has completed and its
response been received.

+The TPM emulator supports the following types of virtual machine migration:
+
+- VM save / restore (migration into a file)
+- Network migration
+- Snapshotting (migration into storage like QoW2 or QED)
+
+The following command sequences can be used to test VM save / restore.
+
+
+In a 1st terminal start an instance of a swtpm using the following command:
+
+mkdir /tmp/mytpm1
+swtpm socket --tpmstate dir=/tmp/mytpm1 \
+ --ctrl type=unixio,path=/tmp/mytpm1/swtpm-sock \
+ --log level=20 --tpm2
+
+In a 2nd terminal start the VM:
+
+qemu-system-x86_64 -display sdl -enable-kvm \
+ -m 1024 -boot d -bios bios-256k.bin -boot menu=on \
+ -chardev socket,id=chrtpm,path=/tmp/mytpm1/swtpm-sock \
+ -tpmdev emulator,id=tpm0,chardev=chrtpm \
+ -device tpm-tis,tpmdev=tpm0 \
+ -monitor stdio \
+ test.img
+
+Verify that the attached TPM is working as expected using applications inside
+the VM.
+
+To store the state of the VM use the following command in the QEMU monitor in
+the 2nd terminal:
+
+(qemu) migrate "exec:cat > testvm.bin"
+(qemu) quit
+
+At this point a file called 'testvm.bin' should exists and the swtpm and QEMU
+processes should have ended.
+
+To test 'VM restore' you have to start the swtpm with the same parameters
+as before. If previously a TPM 2 [--tpm2] was saved, --tpm2 must now be
+passed again on the command line.
+
+In the 1st terminal restart the swtpm with the same command line as before:
+
+swtpm socket --tpmstate dir=/tmp/mytpm1 \
+ --ctrl type=unixio,path=/tmp/mytpm1/swtpm-sock \
+ --log level=20 --tpm2
+
+In the 2nd terminal restore the state of the VM using the additonal
+'-incoming' option.
+
+qemu-system-x86_64 -display sdl -enable-kvm \
+ -m 1024 -boot d -bios bios-256k.bin -boot menu=on \
+ -chardev socket,id=chrtpm,path=/tmp/mytpm1/swtpm-sock \
+ -tpmdev emulator,id=tpm0,chardev=chrtpm \
+ -device tpm-tis,tpmdev=tpm0 \
+ -incoming "exec:cat < testvm.bin" \
+ test.img
+
+
+Troubleshooting migration:
+
+There are several reasons why migration may fail. In case of problems,
+please ensure that the command lines adhere to the following rules and,
+if possible, that identical versions of QEMU and swtpm are used at all
+times.
+
+VM save and restore:
+ - QEMU command line parameters should be identical apart from the
+ '-incoming' option on VM restore
+ - swtpm command line parameters should be identical
+
+VM migration to 'localhost':
+ - QEMU command line parameters should be identical apart from the
+ '-incoming' option on the destination side
+ - swtpm command line parameters should point to two different
+ directories on the source and destination swtpm (--tpmstate dir=...)
+ (especially if different versions of libtpms were to be used on the
+ same machine).
+
+VM migration across the network:
+ - QEMU command line parameters should be identical apart from the
+ '-incoming' option on the destination side
+ - swtpm command line parameters should be identical
+
+VM Snapshotting:
+ - QEMU command line parameters should be identical
+ - swtpm command line parameters should be identical
+
+
+Besides that, migration failure reasons on the swtpm level may include
+the following:
+
+ - the versions of the swtpm on the source and destination sides are
+ incompatible
+ - downgrading of TPM state may not be supported
+ - the source and destination libtpms were compiled with different
+ compile-time options and the destination side refuses to accept the
+ state
+ - different migration keys are used on the source and destination side
+ and the destination side cannot decrypt the migrated state
+ (swtpm ... --migration-key ... )

When is swtpm ending, when qemu leaves? Hopefully you can do several
migrate commands.

Does that mean the tpmstate directory content must be the same and
thus migrated as well? Can in be empty in the destination? If not,
what should be done to initialize it? Could it be empty instead?

Yes, QEMU does not send it the signal to shut down. We can fall back to
the source if the destination fails.

QEMU migrates the state of the TPM with the CMD_GET_STATEBLOB to
retrieve the state blobs and CMD_SET_STATEBLOB to set them on the
destination. The destination only needs to have the TPM running but the
directory must have been created (--tpmstate dir=...).
One can try this with localhost migration over the network as well, but
I didn't want to show this more complicated scenario in the doc:
destination QEMU:
sudo ./x86_64-softmmu/qemu-system-x86_64 -vnc :11 -enable-kvm -m 1024
-smp 8 -boot d -L /usr/share/seabios -bios bios-256k.bin -boot menu=on
-chardev socket,id=chrtpm,path=/tmp/mytpm2/ctrl.sock -tpmdev
emulator,id=tpm0,chardev=chrtpm -device tpm-tis,tpmdev=tpm0 -monitor
stdio -chardev file,id=pts2,path=/tmp/seabios.log -device
isa-serial,chardev=pts2 /var/lib/libvirt/images/FC27 -incoming "exec:nc
-l 127.0.0.1 12345"
source QEMU:
sudo ./x86_64-softmmu/qemu-system-x86_64 -vnc :10 -enable-kvm -m 1024
-smp 8 -boot d -L /usr/share/seabios -bios bios-256k.bin -boot menu=on
-chardev socket,id=chrtpm,path=/tmp/mytpm1/ctrl.sock -tpmdev
emulator,id=tpm0,chardev=chrtpm -device tpm-tis,tpmdev=tpm0 -monitor
stdio -chardev file,id=pts2,path=/tmp/seabios.log -device
isa-serial,chardev=pts2 /var/lib/libvirt/images/FC27
(qemu) migrate "exec:nc 127.0.0.1 12345"
Just tested again.

Migration has a tcp form that's a bit easier;
-incoming tcp:127.0.0.1:12345
migrate tcp:127.0.0.1:12345

Add a test program for testing the CRB with the external swtpm.
The 1st test case extends a PCR and reads back the value and compares
it against an expected return packet.
The 2nd test case repeats the 1st test case and then migrates the
external swtpm's state along with the VM state to a destination
QEMU and swtpm and checks that the PCR has the expected value now.
