Move the functions in qemu.bbclass to meta/lib/oe/qemu.py as they are generally useful. The qemu.bbclass is still kept, and recipes can continue to use functions from it, though they have become wrapper functions on qemu.py functions. Note that the QEMU_OPTIONS settings are still kept in qemu.bbclass. This sets a clear barrier for people to use qemu user mode.
