Re: [PATCH v2 04/13] libxenguest: short-circuit "all-dirty" handling

For one it is unnecessary to fill a perhaps large chunk of memory with
all ones. Add a new parameter to send_dirty_pages() for callers to
indicate so.

Then it is further unnecessary to allocate the dirty bitmap altogether
when all that's ever going to happen is a single all-dirty run.
