sometimes circuit_get_open_circ_or_launch() can return 0 but not
return a circuit, e.g. because too many circuits have failed recently
so the new one didn't launch. we need to tolerate that.

We don't think this is exploitable, but best to fix it anyway.

Turn tor_strpartion into a swiss-army-knife function, so it can terminate or not-terminate appropriately.

Include a dir-signing-key token in directories to tell the parsing entity which key is being used to sign.  This is the first step in obsoleting the dirservers file.

Make base-64-encoded DER work, including workaround for ugly openssl misfeature that makes base64 decoding fail when you strip out the newlines.

Implement (temporarily) a base64-encoded-DER format for RSA keys; make it easier to generate fingerprints with no space

then it serves *that directory* to others who ask for a copy of the

  o Bugfixes on pre1:
    - Make fetching a cached directory work for 64-bit platforms too.
    - Make zlib.h a required header, not an optional header.
