Andre Puschmann 21b3635ae4 rlc_am_lte: refactor retransmit_pdu() to send different SNs
it seems that different SNs should be retransmitted depending
on the actual situation. In case of pollRetx timer expiration,
vt_s - 1 should actually be resent.

This patch prepares the function to accept different SNs but
leaves it to send vt_a by default. The RLC AM test would need
to changed as well to not fail.

Francisco b06f16891d use of a single array-based pool of RLC AM PDU segments to build data PDUs, while
avoiding any allocations.
Each segment stores its own PDCP SN and RLC SN and has two pointers,
one for the next segment of the same RLC PDU, and another for the next segment
of the same PDCP PDU.

Andre Puschmann 48537f3fe7 pdcp,rlc: increase number of PDCP SDUs for notification from RLC
the current value of 256 limits the number of PDCP SDUs that can be
notified from RLC. The limit is quickly hit when too many SDUs
are in flight. This can cause unwanted log entries and weird PDCP
behaviour.

the patch increases the value to 1024, which still can be too few if
many smaller SDUs are traveling.

The patch also set the log level to warning to quicker spot
misconfigs in logs.

Fixes #2616

Francisco dc763b5045 rlc am - fix bugs in buffered_pdcp_pdu_list

Francisco ebbb74e639 rlc am - use of circular_map container in RLC AM window
The window elements are not being correctly cleaned up when clear() is called
or when overwritten by newer SN. Furthermore, the window count member is not being
correctly updated when the insertion of a newer SN overwrites the previous one.

I used the circular_map container to avoid this sort of bugs

Pedro Alvarez 5bc55ec48c Changed discard_if to appyly_if in circular_buffer.h.
This was done so it would work when circular buffer holds other things
that are not unique_pointers. Queue and pop_func had to be made public
to be able to call the pop_func when an SDU is discarded.
