b5e6bbc01d Do not even try to keep going on a socket with socklen==0
Back in #1240, r1eo linked to information about how this could happen
with older Linux kernels in response to nmap.  Bugs #4545 and #4547
are about how our approach to trying to deal with this condition was
broken and stupid.  Thanks to wanoskarnet for reminding us about #1240.

This is a fix for the abovementioned bugs, and is a bugfix on
0.1.0.3-rc.

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.

df9b76460c New 'DisableNetwork' option to prevent Tor from using the network
Some controllers want this so they can mess with Tor's configuration
for a while via the control port before actually letting Tor out of
the house.

We do this with a new DisableNetwork option, that prevents Tor from
making any outbound connections or binding any non-control
listeners.  Additionally, it shuts down the same functionality as
shuts down when we are hibernating, plus the code that launches
directory downloads.

To make sure I didn't miss anything, I added a clause straight to
connection_connect, so that we won't even try to open an outbound
socket when the network is disabled.  In my testing, I made this an
assert, but since I probably missed something, I've turned it into a
BUG warning for testing.

00b2b69add Fix names of functions that convert strings to addrs
Now let's have "lookup" indicate that there can be a hostname
resolution, and "parse" indicate that there wasn't.  Previously, we
had one "lookup" function that did resolution; four "parse" functions,
half of which did resolution; and a "from_str()" function that didn't
do resolution.  That's confusing and error-prone!

The code changes in this commit are exactly the result of this perl
script, run under "perl -p -i.bak" :

  s/tor_addr_port_parse/tor_addr_port_lookup/g;
  s/parse_addr_port(?=[^_])/addr_port_lookup/g;
  s/tor_addr_from_str/tor_addr_parse/g;

This patch leaves aton and pton alone: their naming convention and
behavior is is determined by the sockets API.

More renaming may be needed.

052b95e2f1 Refactor connection_bucket_refill(_helper) to avoid roundoff
We were doing "divide bandwidth by 1000, then multiply by msec", but
that would lose accuracy: instead of getting your full bandwidth,
you'd lose up to 999 bytes per sec.  (Not a big deal, but every byte
helps.)

Instead, do the multiply first, then the division.  This can easily
overflow a 32-bit value, so make sure to do it as a 64-bit operation.

0de8afd8f5 Split out rephist parts of buckets_decrement
For bufferevents, we had all of connection_buckets_decrement() stubbed
out.  But that's not actually right!  The rephist_* parts were
essential for, inter alia, recording our own bandwidth.  This patch
splits out the rephist parts of connection_buckets_decrement() into their
own function, and makes the bufferevent code call that new function.

Fixes bug 3803, and probably 3824 and 3826 too.  Bugfix on 0.2.3.1-alpha.

59d0f750c9 Apply rate-limiting to the lowest bufferevent in the stack.
When we're doing filtering ssl bufferevents, we want the rate-limits
to apply to the lowest level of the bufferevent stack, so that we're
actually limiting bytes sent on the network. Otherwise, we'll read
from the network aggressively, and only limit stuff as we process it.

6596aa022f Implement protocol-type isolation correctly.
Previously we'd just looked at the connection type, but that's
