xen: TPM Emulator for Xen stubdoms

TPM Emulator is a software-based TPM and MTM emulator. This TPM Emulator
recipe creates a static library that is cross-compiled against MiniOS,
Xen, LWIP, Newlib, PolarSSL, and the stubdom-specific GMP headers and
subsequently used during the cross-compilation and linking of the Xen
vTPM and vTPM Manager stubdomains.

The current Xen source code is hardcoded to fetch a specific version of
this package. The patch files originate from the Xen/stubdom source
tree. This recipe provides the flexibility to change version or modify
the patches.
