Make it possible to retry \fBSSL_write()\fR with changed buffer location

the misconception that non-blocking \fBSSL_write()\fR behaves like
non-blocking \fBwrite()\fR.
.IP "\s-1SSL_MODE_AUTO_RETRY\s0" 4
.IX Item "SSL_MODE_AUTO_RETRY"
Never bother the application with retries if the transport is blocking.
If a renegotiation take place during normal operation, a
\&\fBSSL_read\fR\|(3) or \fBSSL_write\fR\|(3) would return
with \-1 and indicate the need to retry with \s-1SSL_ERROR_WANT_READ.\s0
In a non-blocking environment applications must be prepared to handle

In a blocking environment, applications are not always prepared to
deal with read/write operations returning without success report. The
flag \s-1SSL_MODE_AUTO_RETRY\s0 will cause read/write operations to only
return after the handshake and successful completion.
.IP "\s-1SSL_MODE_RELEASE_BUFFERS\s0" 4
.IX Item "SSL_MODE_RELEASE_BUFFERS"
When we no longer need a read buffer or a write buffer for a given \s-1SSL,\s0
