vmm(4): send all port io emulation to userland
Simplify things by sending any io exits from IN/OUT instructions
to userland instead of trying to emulate anything in the kernel.
vmm was sending most pertinent exits to vmd anyways, so this
functionally changes little.
An added benefit is this solves an issue reported by tb@ where i386
OpenBSD guests would probe for a pc keyboard repeatedly and cause
excessive vm exits. (The emulation in vmm was not properly handling
these port reads.)
While here, make the assignment of the VEI_DIR_{IN,OUT} enum values
not assume the underlying integer the compiler may assign.

Drive i8253 with CLOCK_MONOTONIC. Ensures that the olatch decrements uniformly, independent of system wall clock jumps. While here, roll the olatch computation in i8253_do_readback() into a loop, and leverage the timespec macros in sys/time.h. Both make the code a lot more readable. ok 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@

Various i8253/i8254 implementation improvements - Fix an error that used the wrong i/o latch index on reads (resulting in erratic counter values possibly being read). Also do proper return size setting (don't clobber %eax high bits). This diff also implements counter readback mode, which is used in seabios.
