dccp ccid-3: Fix a loss detection bug
This fixes a bug in the logic of the TFRC loss detection:
* new_loss_indicated() should not be called while a loss is pending;
* but the code allows this;
* thus, for two subsequent gaps in the sequence space, when loss_count
has not yet reached NDUPACK=3, the loss_count is falsely reduced to 1.
To avoid further and similar problems, all loss handling and loss detection is
now done inside tfrc_rx_hist_handle_loss(), using an appropriate routine to
track new losses.
Further changes:
----------------
* added a reminder that no RX history operations should be performed when
rx_handle_loss() has identified a (new) loss, since the function takes
care of packet reordering during loss detection;
* made tfrc_rx_hist_loss_pending() bool (thanks to an earlier suggestion
by Arnaldo);
* removed unused functions.
