Pau Espin fbfab297ee Split identity_lv param into mi+mi_len
It's not really needed to have those together in some function calls,
and makes it more difficult to follow the code. Furthermore, new callers
not having content already aligned (len+value) will be using these
functions in forthcoming commits.

Pau Espin 1e6eb30f51 Clarify (M)CS related VTY attributes
Some are used to control (M)CS values for downlink while some do it for
uplink. Let's make clear which one is used for what. Take the chance to
document the fields a bit better than they were.

Some more information about the origin of cs_downgrade_threshold can be
found in the commit introducing it: 70b96aa232.

Vadim Yanitskiy 0bf622e057 gprs_bssgp_destroy(): fix memleak and NULL-pointer dereference
So far there was a memory leak, because free()ing 'the_pcu.bctx'
would cause ASAN to complain. And that's reasonable, because it
needs to be freed properly. Moreover, 'the_pcu.bctx' may simply
be uninitialized in some cases, e.g. when OsmoPCU is terminated
before connecting to the SGSN.

Let's use the new bssgp_bvc_ctx_free() from libosmogb.

Vadim Yanitskiy ef444142c8 BSSGP: do not reject SUSPEND ACK / NACK messages
Both BSSGP SUSPEND ACK and NACK messages use BVCI=0 (signaling),
which always exists. Claiming that BVCI=0 is unknown is wrong.

Instead of adding both BSSGP_PDUT_SUSPEND_{ACK,NACK} to the 'if'
statement, let's rather avoid rejection for all BVCI=0 messages,
as there may be other unlisted message types.

Pau Espin 05bca3524a Fix assertion hit upon CCCH Paging Request
Recent commit added an assertion to check for buffer boundaries and it
actually gets hit.
One of the 2 code paths calling pcu_l1if_tx_pch() was passing a buffer
of 23 bytes while one of maximum 22 is expected (because plen is not set
in the buffer but set inside pcu_l1if_tx_pch()).
So it seems before the assert, that code path was actually writing 1
byte outside the boundaries of data buffer, since bitvec_pack() uses
data_len field of bitvec.

Vadim Yanitskiy cef2f843b4 VTY: fix command 'show tbf all': properly filter TBFs
For a long time the VTY command to show all active TBFs was broken.
The TBF filtering (by allocation origin) logic allows one to show
TBFs allocated on CCCH, PACCH, or on both of them. In the latter
case we have been checking whether a TBF was allocated on both
logical channels at the same time.

Let's fix this by passing a flag-mask instead of boolean arguments.
To be able to use GPRS_RLCMAC_FLAG_* definitions from "tbf.h", let's
exclude them from "#ifdef __cplusplus ... #endif" block.

Pau Espin 28f160e76c Introduce osmo_tdef infra and timer VTY commands
This will allow for configuration of some of the timers by the user,
and allow him to inspect current values being used.
It will be also useful for TTCN3 tests which may want to test some of
the timers without having to wait for lots of time.

Timers are splitted into 2 groups: BTS controlled ones and PCU controlled
ones. The BTS controlled ones are read-only by the user (hence no
"timer" VTY command is provided to change them).

TbfTest.err output changes due to timers being set up correctly as a
consequence of changes. Other application such as pcu_emu.cpp and
pcu_main.cpp had to previosuly set the initial values by hand (and did
so), but apparently TbfTest.c was missing that part, which is now fixed
for free.
