Make the vTPM hotplug script use the UUID of the vTPM instance for
associating it with its instance number rather than the name of the
domain.
Also change the cleanup in the xm test to use the atexit mechanism
rather than explicitly calling a function to clean up.

This prevents an error from being logged. Use the wrapped command for
reading from the xenstore instead of the native one.

xm test suite). If no vTPM has been attached, the local migration
proceeds as usual.

In the external device migration script I am introducing a subtype

unparsed parameters are passed to the called script.

contains code that allows to at least detect local migration of a
virtual machine and handles this for the virtual TPM (results in a no-op
for local migr.). If migration of a virtual machine with attached vTPM
to another machine is attempted, XenD will return an error.

- introduces two basic tests for the virtual TPM (skipped on hardware
where a TPM is not available or vtpm manager has not been started
manually before)
- adapts the Makefiles to make the test cases available
- splits up the hotplug files into two files where the vtpm-common.sh
can be sourced by 'other' scripts as well
- uses echo "$var" to return variables from functions
- gets rid of the 'set +e" work-around
- introduces a script (vtpm-delete) to delete entries from the virtual
TPM directory in /etc/xen/vtpm.db
The xm-tests will skip over the 2nd test on most systems and the patch
has otherwise no effect on existing tests.

Fix a recently found problem in tpm.c, move the vtpm sysfs
entry to /sys/device/platform/tpm_vtpm and add locking in
the vtpm hotplug script.
