make mmap test experiment with different amounts of mapping

This is sort of prototype-ish, but the idea is that we use SetMaxMapCount
from syswrap, which already exists, to let us test edge cases like
"what happens if you only sometimes have mapped data".

generation testing and paranoia features

We might have a problem with a stale mmap, and to try to narrow it down
a bit, we add some sanity-checking features and panic recovery to the
generation Transaction code.

This is pretty experimental.

don't corrupt files when mmap fails

In some cases, after a snapshot, if mmap fails, we could write
a duplicate of the bitmap to the file, creating cryptic "unknown
op type: 60" messages. This doesn't fix those files, but it stops
making them.
