reading from the xenstore instead of the native one.

proceeds as usual.

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.
