Refactor buffers; implement descriptors.
...
'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.

Start of port to win32. Missing are:
...
- signal support
- forking for DNS farm
- changes for async IO
- daemonizing
In other words, some files still don't build, and the ones that do build,
do nonblocking IO incorrectly.
I'm also not checking in the project files till I have a good place
for them.

Be smarter about getting key matter from DH.
...
Formerly, once we had g^xy, we took the last N bytes from g^xy.
Now, we take SHA(g^xy || [0]) || SHA1(g^xy || [1]) || ... , in order
to use all bits from g^xy equally, and generate as much key material
as we need.

laying the groundwork for dynamic router lists

revamped the router reading section
reference counting for crypto pk env's (so we can dup them)
we now read and write pem pk keys from string rather than from FILE*,
in anticipation of fetching directories over a socket
(so now on startup we slurp in the whole file, then parse it as a string)
fixed a bug in the proxy side, where you could get some circuits
wedged if they showed up while the connection was being made
