authorities can stop serving dummy v1 directory documents

Define new new consensus method 14 adding "a" lines to vote and
consensus documents.
From proposal 186:
As with other data in the vote derived from the descriptor, the
consensus will include whichever set of "a" lines are given by the
most authorities who voted for the descriptor digest that will be
used for the router.
This patch implements this.

|
The smart part of this is based on an approach and a suggestion by
rransom. The unsmart part is my own fault.
|
|
This eliminates duplicated code, and lets us test a hairy piece of
functionality.

This lets a routerinfo_t have a single IPv6 or-address, and adds
support for formatting and parsing those lines.

We need to make sure that the worst thing that a weird consensus param
can do to us is to break our Tor (and only if the other Tors are
reliably broken in the same way) so that the majority of directory
authorities can't pull any attacks that are worse than the DoS that
they can trigger by simply shutting down.
One of these worse things was the cbtnummodes parameter, which could
lead to heap corruption on some systems if the value was sufficiently
large.
This commit fixes this particular issue and also introduces sanity
checking for all consensus parameters.

This was the only flag in routerstatus_t that we would previously
change in a routerstatus_t in a consensus. We no longer have reason
to do so -- and probably never did -- as you can now confirm more
easily than you could have done by grepping for is_running before
this patch.
The name change is to emphasize that the routerstatus_t is_running
flag is only there to tell you whether the consensus says it's
running, not whether it *you* think it's running.

In its zeal to keep me from saying memset(x, '0', sizeof(x)), Coverity
disallows memset(x, 48, sizeof(x)). Fine. I'll choose a different
magic number, see if I care!

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.

Found by coverity
test_mem_op_hex was leaking memory, which showed up in a few
tests.
Also, the dir_param test had a memleak of its own.

Should quiet a coverity warning.
