The current version doesn't address the attacks involving pages

Here is change log from V3 To V4:
- Fixing spelling/grammar mistakes suggested by Randy Dunlap
- Changing the hypercall interface to be able to process multiple pages
per one hypercall also suggested by Randy Dunlap. It turns out that
this will save lots of vmexist/memory slot flushes when
guest virtual address -> guest physical
address remapping, but there are plans to fix that.

This will help sharing data into the slot_level_handler callback. In my
case I need to a share a counter for the pages traversed to use it in some
bitmap. Being able to send arbitrary memory pointer into the
slot_level_handler callback made it easy.
