[A part of this change affecting ssl/s3_lib.c was accidentally commited
separately, together with a compilation fix for that file;
see s3_lib.c CVS revision 1.133 (http://cvs.openssl.org/chngview?cn=19855).]

Check return values of HMAC in tls_P_hash and tls1_generate_key_block.
Although the previous version could in theory crash that would only happen if a
digest call failed. The standard software methods can never fail and only one
ENGINE currently uses digests and it is not compiled in by default.
directly by SSL/TLS SHA2 certificates are becoming more common and
applications that only call SSL_library_init() and not
OpenSSL_add_all_alrgorithms() will fail when verifying certificates.
Update docs.
Also, add missing CHANGES entry for CVE-2009-3245 (code changes submitted to this branch on 23 Feb 2010),
and further harmonize this version of CHANGES with the versions in the current branches.
initial connection to unpatched servers. There are no additional security
concerns in doing this as clients don't see renegotiation during an
attack anyway.

Since SSLv2 doesn't support renegotiation at all don't reject it if
legacy renegotiation isn't enabled.
Also can now use SSL2 compatible client hello because RFC5746 supports it.

More robust fix and workaround for PR#1949. Don't try to work out if there
is any write pending data as this can be unreliable: always flush.
ctrl is incorrectly implemented (e.g. some versions of Apache). As a workaround
call both BIO_CTRL_INFO and BIO_CTRL_WPENDING if it returns zero. This should
both address the original bug and retain compatibility with the old behaviour.
algorithms not found when an application uses PKCS#12 and only calls
SSL_library_init() instead of OpenSSL_add_all_algorithms(). Simple
work around is to add the missing algorithm (40 bit RC2) in
SSL_library_init().

Fix DTLS connection so new_session is reset if we read second client hello:
new_session is used to detect renegotiation.
Although it will be many years before TLS v2.0 or later appears old versions
of servers have a habit of hanging around for a considerable time so best
if we handle this properly now.
