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

(cherry picked from commit c52c3b5e)

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

(cherry picked from commit 0ac62399)

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

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

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
offset value. This commit restores the fragment offset from the last
attempt.

It seems like some tar versions don't like the name:id form for

that seems to be the most appropriate user/group to assign ownership
to.  It matters very little when unpacking either way.

When parsing a combined structure pass a flag to the decode routine
so on error a pointer to the parent structure is not zeroed as
this will leak any additional components in the parent.

This can leak memory in any application parsing PKCS#7 or CMS structures.

In the DTLS ClientHello processing the return value is stored in |ret| which
by default is -1. We wish to return 1 on success or 2 on success *and* we
have validated the DTLS cookie. Previously on successful validation of the
cookie we were setting |ret| to 2. Unfortunately if we later encounter an
error then we can end up returning a successful (positive) return code from
the function because we already set |ret| to a positive value.

This does not appear to have a security consequence because the handshake
just fails at a later point.
