This code handles the new ORPort options, and incidentally makes all
remaining port types use the new port configuration systems.
There are some rough edges! It doesn't do well in the case where your
Address says one thing but you say to Advertise another ORPort. It
doesn't handle AllAddrs. It doesn't actually advertise anything besides
the first listed advertised IPv4 ORPort and DirPort. It doesn't do
port forwarding to them either.
It's not tested either, it needs more documentation, and it probably
forgets to put the milk back in the refrigerator.

Some of these were a little tricky, since they touched code that
changed because of the prop171 fixes.
Because tunneled connections are implemented with buffervent_pair,
writing to them can cause an immediate flush. This means that
added to them and then checking to see whether their outbuf is
empty is _not_ an adequate way to see whether you added anything.
This caused a problem in directory server connections, since they
would try spooling a little more data out, and then close the
connection if there was no queued data to send.
This fix should improve matters; it only closes the connection if
there is no more data to spool, and all of the spooling callbacks
are supposed to put the dirconn into dir_spool_none on completion.
This is bug 3814; Sebastian found it; bugfix on 0.2.3.1-alpha.
One-hop dirconn streams all share a session group, and get the
ISO_SESSIONGRP flag: they may share circuits with each other and
nothing else.
Anonymized dirconn streams get a new internal-use-only ISO_STREAM
flag: they may not share circuits with anything, including each other.
All of the routerset_contains*() functions return 0 if their
routerset_t argument is NULL. Therefore, there's no point in
doing "if (ExcludeNodes && routerset_contains*(ExcludeNodes...))",
for example.
This patch fixes every instance of
if (X && routerstatus_contains*(X,...))
Note that there are other patterns that _aren't_ redundant. For
example, we *don't* want to change:
if (EntryNodes && !routerstatus_contains(EntryNodes,...))
Fixes#2797. No bug here; just needless code.
This is a little error-prone when the local has a different type
from the parameter, and is very error-prone with both have the same
type. Let's not do this.
Fixes CID #437,438,439,440,441.
This lets us make a lot of other stuff const, allows the compiler to
generate (slightly) better code, and will make me get slightly fewer
patches from folks who stick mutable stuff into or_options_t.
const: because not every input is an output!
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.

Here I looked at the results of the automated conversion and cleaned
them up as follows:
If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I
changed it to a fast_memcmp or fast_memeq.
Otherwise if there was a tor_memcmp that could turn into a
tor_memneq or tor_memeq, I converted it.
This wants close attention.
[*] I'm erring on the side of caution here, and leaving some things
as tor_memcmp that could in my opinion use the data-dependent
fast_memcmp variant.
To turn this on, set UseMicrodescriptors to "1" (or "auto" if you
want it on-if-you're-a-client). It should go auto-by-default once
0.2.3.1-alpha is released.
Because of our node logic, directory caches will never use
microdescriptors when they have the right routerinfo available.
Clients and relays haven't used them since early 0.2.0.x. The only
remaining use by authorities learning about new relays ahead of scedule;
see proposal 147 for what we intend to do about that.
We're leaving in an option (FetchV2Networkstatus) to manually fetch v2
networkstatuses, because apparently dnsel and maybe bwauth want them.
This fixes bug 3022.

These were mostly releated to the routerinfo_t->node_t conversion.
If we're picking a random directory node, never pick an excluded one.
But if we've chosen a specific one (or all), allow it unless strictnodes
is set (in which case warn so the user knows it's their fault).
When warning that we won't connect to a strictly excluded node,
log what it was we were trying to do at that node.
When ExcludeNodes is set but StrictNodes is not set, we only use
non-excluded nodes if we can, but fall back to using excluded nodes
if none of those nodes is usable.
