Jeff Cody - April 30, 2014, 2:55 p.m.
The new functionality of common.qemu implements the QEMU control
and communication functionality that was originally in test 085.

This removes that now-duplicate functionality, and uses the
common.qemu functions.

The QEMU commandline changes slightly due to this; in addition to
monitor and qmp i/o options, the new QEMU commandline from inside
common.qemu now introduces -machine accel=qtest.
