dirnode.py: security bug: also use child writecap to derive child enc key,
...
not just the dirnode writecap. The previous code (which only hashed the
dirnode writecap) would use the same key for all children, which is very bad.
This is the correct implementation of #750 .

directories: make the IV for the writecaps in directory entries be computed from the secure hash of the writecap itself
...
This makes encoding of directory entries deterministic, and it is also a tad faster on Macbook Pro than getting a random IV with os.urandom(16).

directories: make initialization of the download cache lazy
...
If you open up a directory containing thousands of files, it currently computes the cache filename and checks for the cache file on disk immediately for each immutble file in that directory. With this patch, it delays those steps until you try to do something with an immutable file that could use the cache.

Tolerate unknown URI types in directory structures. Part of #683 .
...
The idea is that future versions of Tahoe will add new URI types that this
version won't recognize, but might store them in directories that we *can*
read. We should handle these "objects from the future" as best we can.
Previous releases of Tahoe would just explode. With this change, we'll
continue to be able to work with everything else in the directory.
The code change is to wrap anything we don't recognize as an UnknownNode
instance (as opposed to a FileNode or DirectoryNode). Then webapi knows how
to render these (mostly by leaving fields blank), deep-check knows to skip
over them, deep-stats counts them in "count-unknown". You can rename and
delete these things, but you can't add new ones (because we wouldn't know how
to generate a readcap to put into the dirnode's rocap slot, and because this
lets us catch typos better).
