Cedric Roux d262d152ec rlc v2: implement SOstart/SOend in NACK reporting 
The necessity of SOstart/SOend was understood after email exchanges with
David Breaux <davidbreaux67@gmail.com>.

See openair2/LAYER2/rlc_v2/tests/test46.h for some details.

Basically if we NACK without SOstart/SOend then the other end of the RLC
channel will consider all the bytes as NACKed and will have to resend them
all. If another status is then reported before all the bytes are sent,
and because we don't use SOstart/SOend this status will NACK all the bytes
again, then all the bytes are to be sent again. And the cycle repeats.
It will end with a max retx reached (which triggers RLF, Radio Link Failure).

The function put_bit in openair2/LAYER2/rlc_v2/rlc_pdu.c has been changed
too, maybe introducing some performance issues.

Cedric Roux 25ab3a5ed3 rlc v2: change time keeping 
RLC has timers. We need to keep track of time. We chose to not use
realtime but 'processing time'. That is we send a tick to RLC for every
subframe when it is processed by the softmodem. Before this commit we
used to increase time in the function mac_rlc_status_ind which may not be
called every subframe (especially in TDD mode). So we need another way
to keep track of time.

We introduce rlc_tick() and call it in eNB_dlsch_ulsch_scheduler, which
is called every subframe, both in FDD and TDD.

We also call rlc_tick() in the function ru_thread_synch() because
pdcp_run() and rrc_rx_tx() are called there too.

It may not be the best solution. To be revised if needed.

Note: the UE has not been touched. Some modification is needed for the UE
too, most probably.
