vmd(8): ignore masks on asserts, use synchronous deasserts. The i8259 was considering the state of the mask register when a device requested raising the bit in the interrupt request register. This caused a race condition where if the virtio device asserted the irq while it was masked in the i8259 by the vm, we'd miss the interrupt request. The device and the pic would become out of sync and users reported virtio block device stalls as the vioblk(4) driver would starve, waiting for an interrupt that will never arrive. The mask is now considered only at ack time, when finding possible interrupts to inject. This bug was never a problem previously as virtio devices were emulated synchronously. Deasserts related to the vcpu reading the virtio isr register are also made now in response to the read request instead of issued asynchronously. This removes a subsequent race condition. Testing from mbuhl@, stsp@, and Florian Riehm. ok mlarkin@

Initialize data before passing it to get_input_data. Strictly speaking this is not necessary as all used bits of the uint32_t are zeroed. ok mlarkin

cleanup vmd(8) includes and header files Lots of organic growth other the years lead to unnecessary includes (proc.h everywhere) and odd dependencies between header files. This cleans things up a bit to help with upcoming cleanup around dhcp code. No functional change. "go for it" mlarkin@

Adds functions to read and write state of devices in vmd. This is required for implementing vmctl send and vmctl receive. vmctl send / receive are two new options that will support snapshotting VMs and migrating VMs from one host to another. The atomicio files are copied from usr.bin/ssh. Patch from Pratik Vyas; this project was undertaken at San Jose State University along with his three teammates, Ashwin, Harshada and Siri with mlarkin@ as the advisor. OK mlarkin@

Handle master/slave PIC vector base properly. OpenBSD uses 0x20/0x28 (respectively). Seabios uses 0x8/0x78 and linux uses 0x30/0x38. Respond properly to PIC vector base assignment and calculate VMX injection vectors based on current values, instead of always assuming OpenBSD defaults. Needed for both seabios serial console support as well as linux guest support. Tested on -current as is, does not break existing OpenBSD guest support.
