Andre Puschmann a09fb95c25 proc_ra: protect RA procedure from concurrent thread access 
that patch addreses issue #2199 by defering RA-related calls that
are executed from within PHY workers.

The time-critical bits of more complex functions such as tb_decoded()
are still executed in the PHY worker thread but the state machine
manipulation is defered.

Andre Puschmann 3573644624 srsue: fix stdout metrics print when scells aren't configured yet 
during MAC reset, scells are reset to and their PCI is set to UINT32_MAX
which results in malformatted stdout prints, see below:

Random Access Transmission: seq=16, ra-rnti=0x2
Random Access Transmission: seq=14, ra-rnti=0x2
 0   4   -24    24  -1.1u   1.0   140  0.50    0.0     0%   0.0   0.0    0.0    0.0    67%

this patch checks the configured PCI value against UINT32_MAX and
prints "n/a" in case the scells aren't set yet.

Andre Puschmann 7cf919e2af Fix MAC PDU packing after sending Truncated BSR (#2004) 
* mac_test: add extended TBSR unit test

unit test to MAC UL packing after sending a TBSR

this fixes the MAC issues described in issue #2002

* mux: fix updating of LCG buffer state after packing PDU

we've previously lowered the buffer state of the LCG according
to the bytes that have been scheduled, but not according to
those that have been actually included in the PDU.

* proc_bsr: fix LCG buffer state updating for TBSR

when sending a TBSR do not update the internal buffer
state of the BSR proc.

This caused issues because the buffer state for all LCG that
are not included in the TBSR are set to zero, although at least
one LCG does have data to transmit.

Andre Puschmann e89254ad1f mac_test: fix mac_ra_test according to BSR changes 
the BSR routine had a bug in which it would generate a BSR even
before the reTx timer expires if new data becomes availble
for a LCID that already had data and a BSR was already sent.

The RA test here relies on a BSR in the generated MAC PDU to pass.

However, since after fixing the BSR bug the PDU the MUX unit
no longer generates a BSR, we need generate data for a LCID
which has higher priority than the one for which a BSR has
already been sent.

Andre Puschmann 7352bfa4bd mac_test: add unit test for retxBSR timer 
this test varifies the correct operation of the retxBSR timer.
the first PDU includes a long BSR to indicate more LCGs have
data to transmit. The retxBSR timer is started and subsequent
PDUs should not send a regular BSR.

After the retxBSR timer expires, a UL PDU should again include
a BSR.

Andre Puschmann fab86382c1 mac,rrc: add interface to set SR config explicitly without touching any other MAC function 
when releasing PUCCH/SRS (see 5.3.13 in 36.331) we need to reset the SR config as well.
In our case, SR is handled by MAC so we need to (re-)configure MAC, not all of
MAC though, just SR.

 shall be encoded as a sequence of a four octet IPv4 address field and a
 four octet IPv4 address mask field. The IPv4 address field shall be

Andre Puschmann 624c8142ad ttcn3: refactor cell handling in SS 
this rather large patch changes the way cells are handled in the SS.
It moves RLC and PDCP entities to the cell map of the SS, such that each cell
has its own entities. This allows to support HO operation, for example,
in which two cells need to send SRB messages.

It also extends most of the syssim interface to include the cell name
in all commands so they can be applied on the specified cell only.

Andre Puschmann a7911f0dab pdcp,rlc: refactor SDU queueing policy 
this patch refactors the SDU queuing and dropping policy of the RLC and PDCP layer.
the previous design had issues when packets have been generated at a higher
rate above the PDCP than they could be consumed below the RLC.

When the RLC SDU queues were full, we allowed two policies, one to block on the write
and the other to drop the SDU. Both options are not ideal because they either
lead to a blocking stack thread or to lost PDCP PDUs.

To avoid this, this patch makes the following changes:

* PDCP monitors RLC's SDU queue and drops packets on its north-bound SAP if queues are full
  * a new method sdu_queue_is_full() has been added to the RLC interface for PDCP
* remove blocking write from pdcp and rlc write_sdu() interface
  * all writes into queues need to be non-blocking
  * if Tx queues are overflowing, SDUs are dropped above PDCP, not RLC
* log warning if RLC still needs to drop SDUs
  * this case should be avoided with the monitoring mechanism
