Continuing from previous commit ensure our style is consistent for malloc
return checks.

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.

./Configure [target] --strict-warnings -Wno-pedantic-ms-format
would not add '-pedantic' because it matches '-Wno-pedantic-ms-format',
which was added first.

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: Viktor 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.

The actual implementation has the state of the connection being
controlled with the peer parameter, non-NULL meaning connected and
NULL meaning connected.

BIO_int_ctrl isn't made for the purpose BIO_get_conn_int_port used it
for.

This also changes BIO_C_GET_CONNECT to actually return the port
instead of assigning it to a pointer that was never returned back to
the caller.

Clarify that git format-patch output is preferred for creating patch files.

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.

An OPENSSL_assert was being used which could fail (e.g. on a malloc
failure).

Reviewed-by: Rich Salz <rsalz@openssl.org>

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.

|tls_process_finished| was checking that |peer_finish_md_len| was

|ssl3_final_finish_mac| can ever return a negative value, so the check is
superfluous.
