We would stash the certs in the handshake state before checking them
for validity... and then if they turned out to be invalid, we'd give
an error and free them. Then, later, we'd free them again when we
tore down the connection.
Fixes bug 4343; fix on 0.2.3.6-alpha.
Right now we can take the digests only of an RSA key, and only expect to
take the digests of an RSA key. The old tor_cert_get_id_digests() would
return a good set of digests for an RSA key, and an all-zero one for a
non-RSA key. This behavior is too error-prone: it carries the risk that
we will someday check two non-RSA keys for equality and conclude that
they must be equal because they both have the same (zero) "digest".
Instead, let's have tor_cert_get_id_digests() return NULL for keys we
can't handle, and make its callers explicitly test for NULL.
Also, define all commands > 128 as variable-length when using
v3 or later link protocol. Running into a var cell with an
unrecognized type is no longer a bug.
The conflicts were mainly caused by the routerinfo->node transition.

Most instances were dead code; for those, I removed the assignments.
Some were pieces of info we don't currently plan to use, but which
we might in the future. For those, I added an explicit cast-to-void
to indicate that we know that the thing's unused. Finally, one was
a case where we were testing the wrong variable in a unit test.
That one I fixed.
This resolves bug 3208.
This patch introduces a few new functions in router.c to produce a
more helpful description of a node than its nickame, and then tweaks
nearly all log messages taking a nickname as an argument to call these
functions instead.
There are a few cases where I left the old log messages alone: in
these cases, the nickname was that of an authority (whose nicknames
are useful and unique), or the message already included an identity
and/or an address. I might have missed a couple more too.
This is a fix for bug 3045.
Changed received_netinfo_from_trusted_dir into a
tristate in order to keep track of whether we have
already tried contacting a trusted dir. So we don't
send multiple requests if we get a bunch of skews.
