server: Create file paths as needed
Add support for non-flat source file layouts (e.g. relative paths that
contain directory parts).
Instead of creating the cache directory and possible per-file
subdirectories separately, just create per-file directories on the
fly. This simplifies the code, but means that you won't die until the
first request if your server doesn't have permission to create these
directories.

server: Implement Server._get_file
It would be nice to use sendfile to copy between the HTTPResponse
object [1] and the cache file. Linux supports arbitrary files (not
just sockets) for out_fd since 2.6.33, so the "to the cache file" side
works. However, from sendfile(2) [2]:
The in_fd argument must correspond to a file which supports
mmap(2)-like operations (i.e., it cannot be a socket).
So reading from the HTTPResponse is not going to happen (yet). Once
Linux gains support for socket in_fd, we could use something like:
_os.sendfile(
f.fileno(), response.fileno(), offset=None, count=content_length)
