This adds a TLSv1.0 cipher alias for ciphersuites requiring
at least TLSv1.0: currently only PSK ciphersuites using SHA256
or SHA384 MAC (SSLv3 only supports SHA1 and MD5 MAC).
Reviewed-by: NMatt Caswell <matt@openssl.org>

This disables some ciphersuites which aren't supported in SSL v3:
specifically PSK ciphersuites which use SHA256 or SHA384 for the MAC.

Thanks to the Open Crypto Audit Project for identifying this issue.

The new function SSL_use_certificate_chain_file was always crashing in
the internal function use_certificate_chain_file because it would pass a
NULL value for SSL_CTX *, but use_certificate_chain_file would
unconditionally try to dereference it.

The function tls1_get_curvelist() has an explicit check to see if s->cert
is NULL or not. However the check appears *after* calling the tls1_suiteb
macro which derefs s->cert. In reality s->cert can never be NULL because
it is created in SSL_new(). If the malloc fails then the SSL_new call fails
and no SSL object is created.

Continuing from previous commit ensure our style is consistent for malloc

if we have a malloc |x = OPENSSL_malloc(...)| sometimes we check |x|
for NULL and sometimes we treat it as a boolean |if(!x) ...|. Standardise
the approach in libssl.

The SSL object was being deref'd and then there was a later redundant check
to see if it is NULL. We assume all SSL_foo functions pass a non NULL SSL
object and do not check it.

We were setting |s->renegotiate| and |s->new_session| to 0 twice in
tls_finish_handshake. This is redundant so now we just do it once!
Reviewed-by: NViktor Dukhovni <viktor@openssl.org>

We finish the handshake when we move into the TLS_ST_OK state. At various
points we were also unnecessarily finishing it when we were reading/writing
the Finished message. It's much simpler just to do it in TLS_ST_OK, so
remove the other calls.

A buggy application that call SSL_write with a different length after a
NBIO event could cause an OPENSSL_assert to be reached. The assert is not
actually necessary because there was an explicit check a little further
down that would catch this scenario. Therefore remove the assert an move
the check a little higher up.

This OPENSSL_assert in (d)tls1_hearbeat is trivially always going to be
true because it is testing the sum of values that have been set as
constants just a few lines above and nothing has changed them. Therefore
remove this.
