Timur Pocheptsov 033a1a2793 Add a secure UDP client example
A simple application that establishes DTLS connection(s) and
sends/receives datagrams. Class DtlsAssociation is
essentially a QUdpSocket|QDtls pair: it initiates a handshake,
handles timeouts and errors. After establishing an encrypted
connection it sends messages to the server and processes responses.
