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

VMS: don't use /DSF, turn off CALL_DEBUG instead

It turns out that /DSF didn't do any good for our purposes.  Instead,
remove the CALL_DEBUG flag from any image we link.  This ensures that
we can have debugging information in the image files, but don't
automatically end up in a debugging session upon image activation.

Unfortunately, this means the CALL_DEBUG must be turned on when there
is a need to run with the debugger activated, and to turn it off when
done.  This has been documented in NOTES.VMS.

After a resumption it is documented that SSL_get_peer_cert_chain() will
