Proposal: Distributed Storage for Tor Hidden Service Descriptors

Finally I finished the design for distributing the storage of hidden
service descriptors among the onion routers.

Overview:

The basic idea of this proposal is to distribute the tasks of storing
and serving hidden service descriptors from currently three
authoritative directory nodes among a large subset of all onion routers.
The two reasons to do this are better scalability and improved security
properties. Further, this proposal suggests changes to the hidden
service descriptor format to prevent from new security threads coming
from decentralization and to gain even better security properties.
