beb52352f2 Fix build with automake 1.6 
automake 1.6 doesn't like using a conditional += to add stuff to foo_LDADD.
Instead you need to conditionally define a variable, then non-conditionally
put that variable in foo_LDADD.

ffd5070b04 Convert bufferevents to use rate-limiting. 
This requires the latest Git version of Libevent as of 24 March 2010.
In the future, we'll just say it requires Libevent 2.0.5-alpha or
later.

Since Libevent doesn't yet support hierarchical rate limit groups,
there isn't yet support for tracking relayed-bytes separately when
using the bufferevent system.  If a future version does add support
for hierarchical buckets, we can add that back in.

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.

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.

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.
