Result of testing as eNodeB. modifications for .vcd logging, bugfix in eNB_thread_FH (subframe counter), update of .conf file for new threading parameters. Updates to gtkwave configuration file for new threading.

It creates more problems than it solves.

We replace this approach by a straightforward
synchronous one.

Now in the downlink, at frame f and subframe s
we use HARQ process (f * 10 + s) % 8.
This is similar to uplink scheduling.

That led to uplink two resource blocks to fail being decoded (not always),
due to wrong channel estimation. (As was the previous hotfix for five
resource blocks.)

This commit also includes some cleanup of some historical code that is
not relevant anymore.
