This came about trying to remove the Java-style iterator. It was used to
iterate in reverse order, something QMap can't do, easily, due to lack
of rbegin()/rend(). Instead of writing ugly loops, use a vector of pairs,
fill it, sort it, then iterate over that one in reverse.

The function is const, but the d-pointer doesn't propagate it (raw pointer),
so we need the qAsConst() even here.

The old code iterated over the peer list, inserting active peers into
a QSet, curiously not stopping to search for clients if it had already
determined the peer to be active.
It then iterated over the peers again, storing the indexes of the
peers it had determined to be active in the first loop, in a QList.
It _then_ iterated over the index list, in reverse, calling removeAt()
on the peers list.
<sean parent>That's a remove_if!</sean parent>
The twist is, that only some maximum number of inactive peers should
be removed, just enough to bring the number of peers below a
predefined number.
To solve, use a lambda that keeps track of the number of times it has
returned true, returning false once the count drops to zero. We can't
use a mutable lambda here, since the STL algorithms are allowed to
copy the predicate as many times as they wish, and, indeed, remove_if
is commonly implemented by calling find_if. But the standard
guarantees exactly one application of the predicate per element, so we
can assume that we're not called again on the same element, and
therefore keep a reference to an external count.
With this, what was a horrible mess becomes a single call to remove_if.
Also change a while(--n) c.removeFirst() loop to a single call of
range-erase.

handles timeouts and errors. After establishing an encrypted

It's a simple DTLS server, implemented with QUdpSocket,
QDtlsClientVerifier and QDtls. The server is configured
to use PSK only (it has no certificate/key).
The server uses a single QUdpSocket socket and
de-multiplexes UDP datagrams internally (thus
it can work with several clients simultaneously).
Future update will probably add more options (like
configuring with certificate/key, etc). For now -
it's as minimalistic and simple as possible.

- new-style headers
- redirects should not result in creating an empty file. Since we
