This series of patches adds support for the TPM emulator backend that
is available in QEMU and based on swtpm + libtpms. It allows to attach a
TPM 1.2 or 2 to a QEMU VM. sVirt labels are used for labeling the swtpm
process, its Unix socket, and log file with the same label that the
QEMU process gets. Besides that swtpm is added to the emulator cgroup to
restrict its CPU usage.
The device XML can be changed from a TPM 1.2 to a TPM 2 and back to a
TPM 1.2. The device state is not removed during those changes but only
when the domain is undefined.
The swtpm needs persistent storage to store its state. For that I am
using the uuid of the VM as part of the path since the name of the VM
can be changed. Logfiles, PID files, and socket names are based on the
name of the VM, though.
