Marc Mutz c6a3507de2 SecureUDPServer example: use std::unique_ptr instead of QSharedPointer
The only reason the code used QSharedPointer is that it used QVector
to hold a collection of them, and QVector infamously cannot hold
move-only types such as std::unique_ptr.

Fix by using std::vector<std::unique_ptr> instead. Also, pass the
objeccts into non-sink functions by raw pointer instead of shared_ptr.

As a drive-by, replace clear-following-iterate by the for-exchanged
pattern.
