xen: LWIP source code with patches applied for stubdoms

Browse Source 
lwIP is a small implementation of the TCP/IP stack designed for use in
embedded systems. This lwIP recipe does not configure nor does it build
the product. Instead, this recipe applies the patches normally found in
the Xen/stubdom source tree and creates a source package that can be
used for cross-compiling for MiniOS.

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.
