7920ea55b8 Refactor tor_event_base_once to do what we actually want
This version avoids the timeout system entirely, gives a nicer
interface, and lets us manage allocation explicitly.

406ae1ba5a Use callback-driven approach to block renegotiations.
Also use this new approach in the bufferevents-enabled case.

340809dd22 Get rid of tor_tls_block_renegotiation().
Since we check for naughty renegotiations using
tor_tls_t.server_handshake_count we don't need that semi-broken
function (at least till there is a way to disable rfc5746
renegotiations too).

734d9486f6 Record the states of failing OR connections
This code lets us record the state of any outgoing OR connection
that fails before it becomes open, so we can notice if they're all
dying in the same SSL state or the same OR handshake state.

More work is still needed:
  - We need documentation
  - We need to actually call the code that reports the failure when
    we realize that we're having a hard time connecting out or
    making circuits.
  - We need to periodically clear out all this data -- perhaps,
    whenever we build a circuit successfully?
  - We'll eventually want to expose it to controllers, perhaps.

Partial implementation of feature 3116.

d238d8386f Add a testing-only option to use bufferevent_openssl as a filter
We need filtering bufferevent_openssl so that we can wrap around
IOCP bufferevents on Windows.  This patch adds a temporary option to
turn on filtering mode, so that we can test it out on non-IOCP
systems to make sure it hasn't got any surprising bugs.

It also fixes some allocation/teardown errors in using
bufferevent_openssl as a filter.

ce0a89e262 Make Tor work with OpenSSL 0.9.8l
To fix a major security problem related to incorrect use of
SSL/TLS renegotiation, OpenSSL has turned off renegotiation by
default.  We are not affected by this security problem, however,
since we do renegotiation right.  (Specifically, we never treat a
renegotiated credential as authenticating previous communication.)
Nevertheless, OpenSSL's new behavior requires us to explicitly
turn renegotiation back on in order to get our protocol working
again.

Amusingly, this is not so simple as "set the flag when you create
the SSL object" , since calling connect or accept seems to clear
the flags.

For belt-and-suspenders purposes, we clear the flag once the Tor
handshake is done.  There's no way to exploit a second handshake
either, but we might as well not allow it.

c4b8fef362 Remove svn $Id$s from our source, and remove tor --version --version.
The subversion $Id$ fields made every commit force a rebuild of
whatever file got committed.  They were not actually useful for
telling the version of Tor files in the wild.

Make dumpstats() log the size and fullness of openssl-internal buffers, so I can test my hypothesis that many of them are empty, and my alternative hypothesis that many of them are mostly empty, against the null hypothesis that we really need to be burning 32K per open OR connection on this.
