Numerous calls assign a return value without asserting its value. Add
assertions and thus also eliminate compiler warnings about unused values.

The rach request contains a relative frame number (Fn % 42432),
while BTS::rcv_rach() accepts the full frame number only.
Since the BTS is always aware of the full frame number this is
not a problem. But for BSC co-located PCU schemes it is a problem
since the rach request only contains the relative frame number
as mentioned above.
The pcu continusly receives frame number updates with the GSM time
indication message. It is simple to re-calculate the full frame
number from that information.
This patch makes BTS::rcv_rach() compatible with relative frame
numbers, while not breaking the compatibility for full frame
numbers

When Packet resource request is received, PCU will generate the
packet access reject if no resources are present. The encoding is done
based on section 7.1.3.2.1 and 8.1.2.5 of 44.060 version 7.27.0 Release 7.
This patch also includes the test case to validate the generated
packet access reject message.
This patch is integration tested on Osmo-trx setup with Ettus B210 board
and LG F70 MS with some simulation code changes in Osmo-pcu.

This adds compression of bitmap in PUAN. The compressed bitmap
is used only if the number of bits in the bitmap does not fit in
the message and there is a gain after compression.
The algorithm is part of libosmocore and so there is dependency
on the libosmocore for compilation.
The algorithm is tested on integration setup by forcing compression.

So far, we used to keep a copy of the header file around in

a third copy in openbsc, let's have the osmo-pcu install the header

In the existing code, GSMTAP messages were only generated in case no
direct PHY access was being used (i.e. in the case all user traffic goes
over the PCU socket). I'm not quite sure what the reason is for that
would be and conclud this is not intentional.
Let's first send the message to GSMTAP and then decide whether to send
it via the direct PHY access or via the PCU socket into the BTS/BSC.

Fix alignment of EPDAN outside the RLC transmit window,
according to section 9.1.8.2.4 in 44.060 version 7.27.0 Release 7.
The specification explains that a bit within the uncompressed bitmap
whose corresponding BSN is not within the transmit window shall be
ignored. Without this fix PCU was dropping the EPDAN message and not
updating the status of BSNs which are inside the RLC window. This patch
updates the status of the BSNs which are inside the window and ignores
the remaining bits.

Release 7. The specification explains that a bit within the
uncompressed bitmap whose corresponding BSN is not within the

drops the EPDAN and does not update status of the BSN which are
inside the window. The test's expectation is corrected along with
the bug fix in a subsequent commit.

The commit broke GPRS service at least for osmo-bts-sysmo on a SysmoBTS 1002
with current master of osmo-bts (ef30f50d5d6d5f863fc147d05ccdceb89284934e).
The error observed is the following log output (was viewing both osmo-bts-sysmo
and osmo-pcu logs interleaved):
<0002> tbf.cpp:874 TBF(TFI=0 TLLI=0x00000000 DIR=UL STATE=WAIT ASSIGN) T3169 timeout during transsmission
<0002> tbf.cpp:893 - Assignment was on CCCH

<0001> pcu_l1_if.cpp:311 RACH request received: sapi=1 qta=0, ra=121, fn=13653
[repeat]
When removing this single commit from current osmo-pcu master, GPRS service
works well on SysmoBTS, with current osmo-bts master.
The TbfTest.err expected output needed adjustment after the revert.
Disclaimer: I am not aware of adverse effects this commit may have. I have no
idea what the WAIT_ASSIGN state is used for -- further review is required.

gcc6 is optimizing if (!this) {CODE} as this is assumed to never be a
std::nullptr here. Move the null check to the caller. In preparation of
removing the check within llc_queue->size(), all callers must check the object
before calling it. Make sure of that: make the llc_queue() access function
protected and offer only a public llc_queue_size() function that incorporates
the NULL check. All current callers are only interested in the
llc_queue_size().

row 4 of Table 10.4.14a.1 of Spec 44.060 version 7.27.0 Release 7. Says
"The previous RLC data block contains a Upper Layer PDU, or a part of it,
that fills precisely the previous data block and for which there is no
length indicator in that RLC data block.
The current RLC data block contains a Upper Layer PDU that either fills
the current RLC data block precisely or continues in the next RLC data block."
So when we receive block with 1st LI: value=0 and Value of E bit in the
same octet as 1, we expect 2 chunks with 1st chunk as length as 0 and complete
and 2nd chunk as length non zero. But with this bug we see only 1 chunk causing
incorrect assembling
