At the moment we flush the write BIO if we send a fatal alert, but not a
warning one. This can mean the warning is never sent if we never do another
write and subsequently flush the BIO. Instead we should just always flush
after writing an alert.

During setup of a reneg test the server can refuse to start reneg.
If that happens we should let the client continue and then fail.

Document that -psk is required to use PSK cipher

s_server has traditionally been very brittle in PSK mode.  If the
client offered any PSK identity other than "Client_identity" s_server
would simply abort.

This is breakage for breakage's sake, and unlike most other parts of
s_server, which tend to allow more flexible connections.

This change accomplishes two things:

 * when the client's psk_identity does *not* match the identity
   expected by the server, just warn, don't fail.

 * allow the server to expect instead a different psk_identity from
   the client besides "Client_identity"

Drop some redundant instructions in reduction in ecp_nistz256_sqr_montx.
Reviewed-by: NRich Salz <rsalz@openssl.org>

Code was added in commit b3c31a65 that overwrote the last ex_data value
using CRYPTO_dup_ex_data() causing a memory leak, and potentially
confusing the ex_data dup() callback.

In ssl_session_dup(), fix error handling (properly reference and up-ref
shared data) and new-up the ex_data before calling CRYPTO_dup_ex_data();
all other structures that dup ex_data have the destination ex_data new'd
before the dup.

Fix up some of the ex_data documentation.

In a recent PR (#3566) it seems that TLSProxy gave up trying to connect to
the server process too quickly. This meant the test failed even though the
server *did* eventually start. Currently we try 3 times to connect with a
0.1 second pause between each attempt. That is probably too aggressive.
