Fix calls to SSL_get_server_tmp_key() in TLSv1.3

The macro SSL_get_server_tmp_key() returns information about the temp key
used by the server during a handshake. This was returning NULL for TLSv1.3
and causing s_client to omit this information in its connection summary.

Fix s_client early data indicator

s_client was always saying that early_data was rejected even when it was
accepted. This was because it was using the wrong test to detect the end
of the handshake. It was using SSL_in_init() which only tells you whether
it is currently processing/sending/expecting handshake messages. It should
use SSL_is_init_finished() which tells you that no handshake messages are
being processed/sent/expected AND we have completed the handshake. In the
early data case we are not processing/sending handshake messages and we
are expecting early data (not a handshake message) - but the handshake has
not yet completed.

Fix resumption after HRR

Commit 6b1bb98fa moved the processing of ClientHello extensions into the
state machine post-processing stage. After processing s->init_num is reset
to 0, so by post-processing we cannot rely on its value. Unfortunately we
were using it to handle the PSK extension. This causes the handshake to
fail.

We were using init_num to figure out the length of ClientHello2 so we can
remove it from the handshake_buffer. The handshake_buffer holds the
transcript of all the messages sent so far. For PSK processing though we
only want to add in a partial ClientHello2. This commit changes things so
we just work out where ClientHello2 starts, working forward from the
beginning of handshake_buffer.
