392e947df5 Fixes on circuitbuild.[ch] based on nick's comments.
* Renamed transport_info_t to transport_t.
* Introduced transport_get_by_name().
* Killed match_bridges_with_transports().
  We currently *don't* detect whether any bridges miss their transports,
  of if any transports miss their bridges.
* Various code and aesthetic tweaks and English language changes.

6a320b9905 Merge remote-tracking branch 'origin/maint-0.2.2'
This merge was a bit nontrivial, since I had to write a new
node_is_a_configured_bridge to parallel router_is_a_configured_bridge.

7039c34519 fix a bridge edge case similar to 2511
If you had configured a bridge but then switched to a different bridge
via the controller, you would still be willing to use the old one.

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.

2b9c5ee301 Preserve bridge download status across SETCONF, HUP
This code changes it so that we don't remove bridges immediately when
we start re-parsing our configuration.  Instead, we mark them all, and
remove all the marked ones after re-parsing our bridge lines.  As we
add a bridge, we see if it's already in the list.  If so, we just
unmark it.

This new behavior will lose the property we used to have that bridges
were in bridge_list in the same order in which they appeared in the
torrc.  I took a quick look through the code, and I'm pretty sure we
didn't actually depend on that anywhere.

This is for bug 3019; it's a fix on 0.2.0.3-alpha.

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.

47a2e5a9ce Don't choose exit nodes without desc available
n_supported[i] has a random value prior to initialization, so a node
that doesn't have routerinfo available can have a random priority.

f962dda8c1 revert most of ef81649d2f
Now we believe it to be the case that we never build a circuit for our
stream that has an unsuitable exit, so we'll never need to use such
a circuit. The risk is that we have some code that builds the circuit,
but now we refuse to use it, meaning we just build a bazillion circuits
and ignore them all.

4851de554d Do not automatically ignore Fast/Stable for exits when ExitNodes is set
This once maybe made sense when ExitNodes meant "Here are 3 exits;
use them all", but now it more typically means "Here are 3
countries; exit from there."  Using non-Fast/Stable exits created a
potential partitioning opportunity and an annoying stability
problem.

(Don't worry about the case where all of our ExitNodes are non-Fast
or non-Stable: we handle that later in the function by retrying with
need_capacity and need_uptime set to 0.)
