'buf_t' is now an opaque type defined in buffers.c .
Router descriptors now include all keys; routers generate keys as
needed on startup (in a newly defined "data directory"), and generate
their own descriptors. Descriptors are now self-signed.
Implementation is not complete: descriptors are never published; and
upon receiving a descriptor, the directory doesn't do anything with
it.
At least "routers.or" and orkeygen are now obsolete, BTW.
