This adds the ability for a vTPM to constrain what localities a given
client domain can use based on its XSM label. For example:
locality=user_1:vm_r:domU_t=0,1,2 locality=user_1:vm_r:watcher_t=5
An arbitrary prefix can be matched by using a '*'.

The vTPM protocol now contains a field allowing the locality of a
command to be specified; pass this to the TPM when processing a packet.
While the locality is not currently checked for validity, a binding
between locality and some distinguishing feature of the client domain
(such as the XSM label) will need to be defined in order to properly
support a multi-client vTPM.

The open/close callbacks in tpmback cannot be properly initalized in
order to catch the initial enumeration events because init_tpmback
clears the callbacks and then asynchronously starts the enumeration of
existing tpmback devices. Fix this by passing the callbacks to
init_tpmback so they can be installed before enumeration.
This also removes the unused callbacks for suspend and resume.

Add the code base for vtpm-stubdom to the stubdom
heirarchy. Makefile changes in later patch.
