Hypervisor interfaces need to be negotiated in order to use some API calls reliably. So add a small set of interfaces to request API versions and query current settings. This allows us to fix some bugs in the hypervisor console: 1) If we can negotiate API group CORE of at least major 1 minor 1 we can use con_read and con_write which can improve console performance quite a bit. 2) When we do a console write request, we should hold the spinlock around the whole request, not a byte at a time. What would happen is that it's easy for output from different cpus to get mixed with each other. 3) Use consistent udelay() based polling, udelay(1) each loop with a limit of 1000 polls to handle stuck hypervisor console.
