Describe the usage of the OCSP callback functions on both the client and
the server side.

Reviewed-by: Viktor Dukhovni <viktor@openssl.org>

It makes no sense to call the OCSP status callback if we are resuming a
session because no certificates will be sent.

Reviewed-by: Viktor Dukhovni <viktor@openssl.org>

If a server sends the status_request extension then it may choose
to send the CertificateStatus message. However this is optional.
We were treating it as mandatory and the connection was failing.

Thanks to BoringSSL for reporting this issue.

BIO_int_ctrl isn't made for the purpose BIO_get_conn_int_port used it
for.

This also changes BIO_C_GET_CONNECT to actually return the port
instead of assigning it to a pointer that was never returned back to
the caller.

A BIO_flush call in the DTLS code was not correctly setting the |rwstate|
variable to SSL_WRITING. This means that SSL_get_error() will not return
SSL_ERROR_WANT_WRITE in the event of an IO retry.

If using DTLS and NBIO then if a second or subsequent handshake message
fragment hits a retry, then the retry attempt uses the wrong fragment

It seems like some tar versions don't like the name:id form for
--owner and --group.  The closest known anonymous user being 0 (root),
that seems to be the most appropriate user/group to assign ownership
to.  It matters very little when unpacking either way.
