xen-console: add save/restore Add code to: 1. Deal with the console page being canonicalized. During save, the console's mfn in the start_info structure is canonicalized to a pfn. In order to deal with that, we always use a copy of the pfn and indirect off that all the time. However, we fall back to using the mfn if the pfn hasn't been initialized yet. 2. Restore the console event channel, and rebind it to the existing irq.

xen: add raw console write functions for debug Add a couple of functions which can write directly to the Xen console for debugging. This output ends up on the host's dom0 console (assuming it allows the domain to write there).
