KVM test: Add a subtest iofuzz
The design of iofuzz is simple: it just generate random I/O port
activity inside the virtual machine. The correctness of the device
emulation may be verified through this test.
As the instrcutions are randomly generated, guest may enter the wrong
state. The test solve this issue by detect the hang and restart the
virtual machine.
The test duration could also be adjusted through the "fuzz_count". And
the parameter "skip_devices" is used to specified the devices which
should not be used to do the fuzzing.
For current version, every activity were logged and the commnad was
sent through a seesion between host and guest. Through this method may
slow down the whole test but it works well. The enumeration was done
through /proc/ioports and the scenario of avtivity is not aggressive.
Suggestions are welcome.
