Upstream changes:

2011-09-02  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

        * Release 0.13

2011-06-12  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

        * OpenSSL/crypto/pkey.c: Add the PKey.check method, mostly
          implemented by Rick Dean, to verify the internal consistency of a
          PKey instance.

2011-06-12  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

        * OpenSSL/crypto/crypto.c: Fix the sign and verify functions so
          they handle data with embedded NULs.  Fix by David Brodsky
          <lp:~lihalla>.

2011-05-20  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

        * OpenSSL/ssl/connection.c, OpenSSL/test/test_ssl.py: Add a new
          method to the Connection type, get_peer_cert_chain, for retrieving
          the peer's certificate chain.

2011-05-19  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

        * OpenSSL/crypto/x509.c, OpenSSL/test/test_crypto.py: Add a new
          method to the X509 type, get_signature_algorithm, for inspecting
          the signature algorithm field of the certificate.  Based on a
          patch from <lp:~okuda>.

2011-05-10  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

        * OpenSSL/crypto/crypto.h: Work around a Windows/OpenSSL 1.0 issue
          explicitly including a Windows header before any OpenSSL headers.

        * OpenSSL/crypto/pkcs12.c: Work around an OpenSSL 1.0 issue by
          explicitly flushing errors known to be uninteresting after calling
          PKCS12_parse.

        * OpenSSL/ssl/context.c: Remove SSLv2 support if the underlying
          OpenSSL library does not provide it.

        * OpenSSL/test/test_crypto.py: Support an OpenSSL 1.0 change from
          MD5 to SHA1 by allowing either hash algorithm's result as the
          return value of X509.subject_name_hash.

        * OpenSSL/test/test_ssl.py: Support an OpenSSL 1.0 change from MD5
          to SHA1 by constructing certificate files named using both hash
          algorithms' results when testing Context.load_verify_locations.

        * Support OpenSSL 1.0.0a.

2011-04-15  Jean-Paul Calderone  <exarkun@twistedmatrix.com>

        * OpenSSL/ssl/ssl.c: Add OPENSSL_VERSION_NUMBER, SSLeay_version
          and related constants for retrieving version information about the
          underlying OpenSSL library.
