Adding the first pass at modifying file serving

to work with indirection.  I've split the
fileserver handler into four pieces:  Mount (which so
far I've just copied wholesale), Configuration (responsible
for reading the configuration file and determining what's allowed),
Metadata (retrieves information about the files), and Content
(retrieves the actual file content).

I haven't added the indirection tests yet, and the configuration
tests are still all stubs.
