xen: PolarSSL recipe and patches for Xen stubdoms

PolarSSL (now mbedTLS) is a lightweight SSL library optimized for
embedded systems. In the case of Xen stubdomains, we are using MiniOS.
This PolarSSL recipe creates a static library that is cross-compiled
against MiniOS, Xen, LWIP, and Newlib headers and subsequently used
during the cross-compilation and linking of the stubdom specific GMP,
TPM Emulator, and 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.
