Cedric Roux 55c83b00f9 hotfix: bug in rx_pucch 
This hotfix does not change the processing at all.
At this point, stat_re == 0, so the behavior is the
same as before. But the code was wrong. There should
have been no test, it's a NACK, period.

Cedric Roux 69ec911283 hotfix: remove HARQ process ID freelist 
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.

Cedric Roux 7d311b57df hotfix: a value was missing in ref24 
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.

Rohit Gupta ba997a2bce Merge branch 'T' into 'develop' 
T

I did some compilation tests using `./build_oai -s --run-group "0101*"`, all was fine.

I ran `lte-softmodem` with the sequans and let it run for a while with both
uplink and downlink UDP low throughput traffic, all was fine.

I ran some TCP tests, downlink 14 Mb/s (because the sequans does not report
a CQI of 15 but 14 maximum, so we don't go to maximum MCS, so 14 Mb/s instead
of 16) with a very clean radio (almost no error in the HARQ processes).

For uplink things are not so clean, it starts at 6 Mb/s and after a while goes
down to 2/3 Mbit/s. Lot's of errors in the HARQ processes, mostly uplink but
also downlink.

This is a both with and without T activated.

So to me it's fine.

The T tracer is a debugging tool. When it's not enabled,
it has zero impact on the processing. I think we need to
do very little tests before merging. I'll let you decide
but to me it's okay!
