This started simply to remove the two page[TARGET_PAGE_SIZE] instances.
These turn into variable length arrays, when I start to allow the page
size to vary for linux-user.

However, the first thing I noticed is that it is silly to write out
target memory to the corefile page by page.  As I started to clean
that up, I noticed some actual errors in the writing of notes.

Finally, we can stop creating local data structures to represent vmas
and rely on the ones over in user-exec.c.
