When sending multiple files from my phone to my PC, kdeconnectd usually received a SIGFPE.
To get the transfer speed it divides the number of bytes received by the elapsed time which can be zero.
Also, since we're only interested in the time that has elapsed, use QElapsedTimer,
which is exactly for this. QTime::elapsed() also needs to take into account potentially
ocurred timezone or DST changes.

Makes it possible to display it and modify it
Introduces a DBusProperty component that can be used if we don't want
to go through the QtDBus property generation hell.
If both devices are in "discovery mode" (ie: both want to keep links
established) and the last one to create the link goes out of discovery
mode, it will close the link when it shouldn't (because the other end still
was "using" it to display it to the user).
As discussed with Albert, move the population of capabilities into the
identity package, making them static along the execution of the link.
When we receive the identityPackage, we collect the plugins we can use with
the device and stick to those. This should simplify the implementation and
remove the possibility to lose packages if packages are received before the
capabilities are processed in the former approach.

Introduces a big fat buffer :(
Actually test the trasfers :)
Takes QSslSocket causistic into account, for some reason QNAM refuses to
mark as finished when the QSslSocket (through QIODevice) closes.
It would be good to look into dropping the QBuffer, doing so with the test
in place will help.
Makes it possible to specify the different properties sent at once,
rather than one by one as we used to do.
Also port whenever possible to the initializer-list syntax.
