This means that "if (E<G) {abc} else if (E>=G) {def}" can be replaced with
"if (E<G) {abc} else {def}"

Doing the second test explicitly made my mingw gcc nervous that we might
never be initializing casename.

For my 64-bit Linux system running with GCC 4.4.3-fc12-whatever, you
can't do 'printf("%lld", (int64_t)x);' Instead you need to tell the
compiler 'printf("%lld", (long long int)x);' or else it doesn't
believe the types match.  This is why we added U64_PRINTF_ARG; it
looks like we needed an I64_PRINTF_ARG too.

Maybe this is what parakeep was complaining about? Really wish he
would stick around more. Playing these guessing games is not fun :(

They are capped to be between 0 and weight_scale (10000) by the code
just before the snprintf.

Still not sure why they generate an empty consensus document..
Too much frobbing going on there.

Also add bwweightscale consensus param. Use it as our
fixed-point calculation width.

Some *_free functions threw asserts when passed NULL. Now all of them
accept NULL as input and perform no action when called that way.

This gains us consistence for our free functions, and allows some
code simplifications where an explicit null check is no longer necessary.

Also, regenerate the detached-signature document whenever any signatures are
successfully added.

Fix a memory leak on directory authorities during voting that was
introduced in 0.2.2.1-alpha. Found via valgrind.

If all authorities restart at once right before a consensus vote, nobody
will vote about "Running", and clients will get a consensus with no usable
relays. Instead, authorities refuse to build a consensus if this happens.

One was a simple buffer overrun; the other was a high-speed pointer
collision.  Both were introduced by my microdescs branch.

This means we need to handle the existence of multiple flavors of signature
in a detached signatures document, generate them correctly, and so on.

This patch introduces a new type called document_signature_t to represent the
signature of a consensus document.  Now, each consensus document can have up
to one document signature per voter per digest algorithm.  Also, each
detached-signatures document can have up to one signature per <voter,
algorithm, flavor>.

The consensus documents are not signed properly, not served, and not
exchanged yet.

This code adds a new field to vote on: "params".  It consists of a list of
sorted key=int pairs.  The output is computed as the median of all the
integers for any key on which anybody voted.

Improved with input from Roger.

Add a new function to derive the declared method list from
consensus_method_is_supported().

The subversion $Id$ fields made every commit force a rebuild of
whatever file got committed.  They were not actually useful for
telling the version of Tor files in the wild.

Add DOCDOC comments for all undocumented functions.  Add missing *s to other comments so that they will get recognized as doxygen.
