Avoid failing s_server when client's psk_identity is unexpected

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"

Add a macro for testing assertion in both debug and production builds

If we have an assert then in a debug build we want an abort() to occur.
In a production build we want the function to return an error.

This introduces a new macro to assist with that. The idea is to replace
existing use of OPENSSL_assert() with this new macro. The problem with
OPENSSL_assert() is that it aborts() on an assertion failure in both debug

cause a reachable assert to be hit then this can be a source of DoS attacks

Fix srp app missing NULL termination with password callback

The password_callback() function does not necessarily NULL terminate
the password buffer, the caller must use the returned length but the
srp app uses this function as if it was doing NULL termination.

This made the -passin and -passout options of "openssl srp"
fail inexpicably and randomly or even crash.

Fixed by enlarging the buffer by one, so that the maximum password length
remains unchanged, and adding NULL termination upon return.

[Rearrange code for coding style compliance in process.]

Fix return code in tls1_mac

The return code from tls1_mac is supposed to be a boolean 0 for fail, 1 for
success. In one place we returned -1 on error. This would cause code calling
the mac function to erroneously see this as a success (because a non-zero
value is being treated as success in all call sites).

Fortunately, AFAICT, the place that returns -1 can only happen on an
internal error so is not under attacker control. Additionally this code only
appears in master. In 1.1.0 the return codes are treated differently.
Therefore there are no security implications.
