84bb5d573c Fix crash/warning bug when we get an unexpected close. 
This was possible if we have already decided to close a bufferevent
connection, but the other side decides to close it first.

4af6887d20 Add support for linked connections with bufferevent_pair. 
Also, set directory connections (linked and otherwise) to use bufferevents.

Also, stop using outbuf_flushlen anywhere except for OR connections.

c6e22ae2b7 Basic bufferevent callbacks 
These are based strongly on connection_handle_read and
connection_handle_write, but hopefully without so much mixture of IO
logic and Tor logic.

Nick Mathewson
a0f4841e2b Refactor SOCKS parsing code to handle evbuffers. 
Now all of the logic is in a parse_socks() function that gets data
from a buf_t or evbuffer-specific wrapper.

94aac84a71 Remove never-actually-finished code to use readv and writev for IO. 
We'll get this feature for free with bufferevents, so there's no good reason
to clone it in Tor.

2579d827ab Use autoreconf, not autoconf&&automake&&etc in autogen.sh 
The autoreconf tool deals much better with detecting which tools to
use on your particular platform, handling cases where your
install-sh script gets stable, and lots of other little tricky
issues.

We still fall back to autoconf&&automake&&etc in the case where
"`which autoreconf 2>/dev/null`" says something we can't run.

This is the first change of the 0.2.3.x series.

83f9667fe8 Bump the Tor version in master to 0.2.3.0-alpha-dev 
0.2.2.x development will continue in branch maint-0.2.2.

master is now out of feature freeze.

Let's not go crazy right away. :)

0a0cc4599f Tweak continuation-and-comment logic 
I think there was a read-off-the-end-of-the-buffer bug that I fixed.
At least I added some good comments, I hope.

1d29ad891e Add new torrc line continuation unit tests 
We want to make sure that we don't break old torrc files that might have
used something like this made-up example:

    ContactInfo UberUser <uber@user.com> # /// Fake email! \\\
    Log info file /home/nick.mathewson/projects/tor-info.log

And we also want to support the following style of writing your torrc:

    ExcludeNodes \
    # Node1337 is run by the Bavarian Illuminati
      Node1337, \
    # The operator of Node99 looked at me funny
      Node99

The code already handles both cases, but the unit test should help prove
it.

4ef9ccc883 Changes to bug1959_part1 on review from arma. 
Significant one: we want to say "not enough entry nodes descriptors, so we
can't build circuits" only when we have 0 descriptors.

52db5c2539 Even more accurate handling for shifting accounting intervals 
Roger correctly pointed out that my code was broken for accounting
periods that shifted forwards, since
start_of_accounting_period_containing(interval_start_time) would not
be equal to interval_start_time, but potentially much earlier.

418e6caeeb New function to load windows system libraries 
This function uses GetSystemDirectory() to make sure we load the version
of the library from c:\windows\system32 (or local equivalent) rather than
whatever version lives in the cwd.

ef5925237d First cut of code to enable RefuseUnknownExits 
The RefuseUnknownExits config option is now a tristate, with "1"
meaning "enable it no matter what the consensus says", "0" meaning
"disable it no matter what the consensus says", and "auto" meaning "do
what the consensus says".  If the consensus is silent, we enable
RefuseUnknownExits.

This patch also changes the dirserv logic so that refuseunknownexits
won't make us cache unless we're an exit.
