Driver framework for libqos

QEMU uses "qtest" as a mechanism for tests to interact with devices. qtest unit tests are currently written in C, using the GTest framework from glib and glue libraries called "libqtest" and "libqos". libqtest implements the qtest socket protocol, while libqos provides utility functions to deal with e.g. guest memory allocation and PCI devices. However, the functionality of libqos is limited. The purpose of the project is to build a driver framework in libqos to enable combinatorial testing. For more information, see Features/qtest_driver_framework.
