This patch adds a TPM device model to the qemu dm for fully virtualized
VMs. It is enabled in the VM only if the user requests a TPM device in
the vm configuration file using the 'vtpm=[...]' line. It enables the
qemu device model command line with a 'vtpm_instance <instance number>'
parameter.

Isn't the vtpm instance stored in xenstore anyway?  If so, then please
add code to ioemu's xenstore.c to read it from there instead of adding
a command line switch.  We're moving away from command line switches
for device configuration.

Minor nitpicks:
- don't use extern to access global variables, add them to vl.h instead.
- add tpm.c to VL_OBJS on a separate line, makes merging it much easier.
