ram: Use memory_region_test_and_clear_dirty

This avoids having to do two walks over the dirty bitmap, once reading
the dirty bits, and anthoer cleaning them.

ram: optimize migration bitmap walking

Instead of testing each page individually, we search what is the next
dirty page with a bitmap operation. We have to reorganize the code to
move from a "for" loop, to a while(dirty) loop.

ram: refactor ram_save_block() return value

It could only return 0 if we only found dirty xbzrle pages that hadn't
changed (i.e. they were written with the same content). We don't care
about that case, it is the same than nothing dirty.

So now the return of the function is how much have it written, nothing...

memory: introduce memory_region_test_and_clear_dirty

This function avoids having to do two calls, one to test the dirty bit, and
other to reset it.
