BIO_int_ctrl isn't made for the purpose BIO_get_conn_int_port used it

This also changes BIO_C_GET_CONNECT to actually return the port

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

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
