7fcfb6c6c5 dtls: Keep track of the connection state and signal it through all the layers
This allows the application to keep track of the underlying DTLS
connection state and act accordingly.

d66aa872ca dtls: Handle errors/close_notify at all steps and propagate through the layers properly
Previously we simply logged errors but never reported them to elements
or even to the user. Fatal errors are now properly reported.

Additionally proper connection closing is implemented based on EOS:
- dtlsenc: EOS will cause close_notify to be sent to the peer and only
           if the peer also sent back close_notify we will forward the
           EOS event.
- dtlsdec: EOS will be forwarded normally, this only means that the
           unterlying transport was closed. On receiving a DTLS packet
           containing close_notify, return EOS and send EOS downstream.

ee55dac8d4 dtls: Use a plain function pointer instead of a GClosure for the send callback
There's not point in using GClosure and going through all the
GValue/libffi infrastructure for each DTLS packet.

e59962850a dtlsenc: Don't warn on GST_FLOW_FLUSHING or GST_FLOW_EOS
Only warn if pushing a buffer returns an actual error to not pollute
logs with confusing warnings.

d8f61515d8 Don't pass default GLib marshallers for signals
By passing NULL to `g_signal_new` instead of a marshaller, GLib will
actually internally optimize the signal (if the marshaller is available
in GLib itself) by also setting the valist marshaller. This makes the
signal emission a bit more performant than the regular marshalling,
which still needs to box into `GValue` and call libffi in case of a
generic marshaller.

Note that for custom marshallers, one would use
`g_signal_set_va_marshaller()` with the valist marshaller instead.

fd609f6bc0 dtls: Use a shared thread pool for the timeouts
This way we will share threads with other DTLS connections if possible, and
don't have to start/stop threads for timeouts if there are many to be handled
in a short period of time.

Also use the system clock and async waiting on it for scheduling the timeouts.

3614302cf8 dtlsenc: Use a GQueue instead of a GPtrArray
Using a GPtrArray as a queue is not very efficient as the whole
array has to be copied whenever an element is removed from the
beginning.
