  1. net: sockets: tls: Fix handshake on non blocking sockets 

    The TLS/DTLS handshake in most cases is a blocking process, therefore
the underlying socket should be in a blocking mode to prevent busy
looping in the handshake thread. Fix this by clearing the O_NONBLOCK
flag on the underlying socket before the handshake, and restoring it
afterards.

  3. net: sockets: tls: Implement TLS_DTLS_CONNECTION_ID option 

    Implement TLS_DTLS_CONNECTION_ID socket option, which enables to use
Connection ID extension for the DTLS session.

The option allows to set the value and the length of the CID to use with
`setsockopt()` function. Setting the CID length to 0, enables the
extension but does not send the own CID to the peer, as described in the
specification.
