working copy storage for RA properties

I'd like to propose that a hashdump file is created where RA libraries can
store properties. There are a couple properties that I'd like to store.

While I could simply mix them in with the normal file/dir props, that would
also open them up to arbitrary manipulation and erroneous flagging that a
change has occurred.

Ideally, I'd like to store properties associated with each directory and
each file.

I believe that we don't need a file per RA, but that all RA modules can
share the same property space. Since we already partition RA modules into
names such as ra_dav, ra_local, etc, they can continue to use that
partitioning within the property namespace.

I would recommend ra-dir-props and ra-props/ as the storage locations.

Thoughts?

Cheers,
