Test KVM dirty logging functionality.
The test creates a standalone memory slot to test tracking the dirty
pages since we can't really write to the default memory slot which still
contains the guest ELF image.
We have two threads running during the test:
(1) the vcpu thread continuously dirties random guest pages by writting
a iteration number to the first 8 bytes of the page
(2) the host thread continuously fetches dirty logs for the testing
memory region and verify each single bit of the dirty bitmap by
checking against the values written onto the page
Note that since the guest cannot calls the general userspace APIs like
random(), it depends on the host to provide random numbers for the
page indexes to dirty.
