kvm: libkvm/qemu: get dirty-page-bitmap based on address range not slot
Since c79baa60813812e8d0e34d998d609e848c093000 qemu does not know
about slots, it uses addresses. Getting the dirty-page-bitmap needs to
adapt to that change.
The user (qemu) requests (from libkvm) dirty page log for all
pages within a specific address range (specifically [0,phys_ram_size-1]).
libkvm iterates through all slots in the address range, calling
a qemu-kvm callback to update qemu's bytemap for each slot within
the requested range.
