3a2d677fa7 Improved workaround for disabled OpenSSL renegotiation.
It turns out that OpenSSL 0.9.8m is likely to take a completely
different approach for reenabling renegotiation than OpenSSL 0.9.8l
did, so we need to work with both. :p   Fixes bug 1158.

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.

a3f1da2ec0 Fix compilation on OpenSSLs with unusual state lists.
"Unusual" in this context means "not the same as nickm's."  We should grow a
better list later.

(Also, move TLS state table to a separate header.)

b8b2935367 Debugging logs for TLS handshake
The big change is to add a function to display the current SSL handshake
state, and to log it everywhere reasonable.  (A failure in
SSL23_ST_CR_SRVR_HELLO_A is different from one in
SSL3_ST_CR_SESSION_TICKET_A.)

This patch also adds a new log domain for OR handshaking, so you can pull out
all the handshake log messages without having to run at debug for everything.
For example, you'd just say "log notice-err [handshake]debug-err file
tor.log".

Make TLS contexts reference-counted, and add a reference from TLS objects to their corresponding context.  This lets us reliably get the certificates for a given TLS connection, even if we have rotated TLS contexts.

New code (disabled for now) to use the SSL context's cert store instead of using its "extra chain cert" list to get our identity certificate sent.  This is a little close to what OpenSSL expects people to do, and it has the advantage that we should be able to keep the id cert from being sent by setting the NO_CHAIN_CERT bit.  I have tried turning new code on, and it seemed to work fine.

873564ea9c Some versions of openssl have an SSL_pending function that erroneously
returns bytes when there is a non-application record pending.

I have no idea when/why this would even happen, but let's catch it and
make sure tor_tls_get_pending_bytes stays correct.
