cc02823d7f Convert instances of tor_snprintf+strdup into tor_asprintf
These were found by looking for tor_snprintf() instances that were
followed closely by tor_strdup(), though I probably converted some
other snprintfs as well.

edcc9981d8 Try to use smartlist_add_asprintf consistently
(To ensure correctness, in every case, make sure that the temporary
variable is deleted, renamed, or lowered in scope, so we can't have
any bugs related to accidentally relying on the no-longer-filled
variable.)

5f0a8dcd2c Initial hacking for proposal 186.
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.

81fe1934af Fix a bufferevent-related bug that killed tunneled dirserv conns
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.

8314fa5e5c Implement sensible isolation for tunneled directory conns
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.

64c8e8edda Kill redundant checks around routerset_contains_*()
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.

47c8433a0c Make the get_options() return const
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!

a5232e0c4c Fix GCC 4.6's new -Wunused-but-set-variable warnings.
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.

b95dd03e5f Log descriptions of nodes, not just nicknames.
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.

59f9097d5c Hand-conversion and audit phase of memcmp transition
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.

4cc348e896 Code to make clients fetch and use microdescriptors for circuit building
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.
