At the moment libosmogb offers no convinient way to send RIM PDUs. Also
parsing an incoming RIM messages into destination, source routing
info and RIM container is not available.

The function bssgp_parse_rim_ri() and bssgp_create_rim_ri() are located
in gprs_bssgp.c, since there is now a gprs_bssgp_rim.c module it makes
more sense to put them there. Also adjust the code a bit so that its
more intuitive to read.

BSSGP RIM uses a number of nested containers to signal RIM application

Right now we end up in situations where only a NS-VC for data (BVCI != 0)
becomes unblocked, but the BSSGP and/or user application code is
notified that the NSE has recovered.
In the case of osmo-gbproxy, this will trigger a BVC-RESET on the
BVCI=0, but that obviously only works if the sig_weight > 0...

gprs_sn2_fr_connect2() is the same as gprs_ns2_fr_connect() with
the lookup-and-create-on-demand of the NSE first.
Rather than copy+paste, they should simply invoke each other.

The local and remote entries should be cleared on SNS Size.
Further it can be cleared when SNS failed (e.g. all NSVC become dead)
so VTY doesn't show old entries before entering SNS Size.

The vty command is used for test cases to reset NSE state.

Prevent memory corruption or segfaults by asserting that NSE and bind
link layer match. A mismatch should never happen and might cause the
bind to access invalid memory when sending because nsvc->priv doesn't
match what it expects.

The SNS code ignored the link type of the bind and just bound to every
bind it could find. This resulted in a segfault when an SNS NSVC tries
to send its UDP messages though frame relay.

The libosmocore TLV parser had a number of insufficient bounds checks
leading to reads beyond the end of the respective input buffer.
This patch
* adds proper out-of-bounds checks to all TLV types
* simplifies some of the existing checks
* introduces test cases to test all the corner cases
where either TAG, or length, or value are not fully contained
in the input buffer.
Thanks to Ilja Van Sprundel for reporting these problems.

This structure is needed in order to identify a given cell within the
BSS during RIM transactions.
The naming was made up by myself since I couldn't find any naming
reference for this kind of data (RAI + CI).
Since LAI + CI = CGI, then RAI + CI = CGI-PS
osmo_rai_name2 family of functions get a "2" suffix due to already

Both LAC and TAC take 2 octets and follow MCC/MNC fields on the wire.
We abuse gsm48_encode_ra() for encoding of MCC/MNC, but it can also
be abused to encode TAC in bssgp_create_rim_ri(). There is no need
to encode '0000'O and then override it with osmo_store16be().

3GPP TS 48.018, section 11.3.65 describes an IE to transfer some control
flags via a RIM container. The IE is essentially just a bitfield, so it
can be parsed by overlaying it with a C-struct. Lets add an appropiate
struct to protocol/gsm_08_18.h

Prior to this patch, it was not possible to gather SET/GET reply
information when implementing a CTRL client using libosmocontrol. This
is specially important when using the GET command, since one wants to
receive the queried value.
CTRL traps can also be handled this way by extending this patch in the
future if needed.

This adds an inter-thread queue "it_q" to libosmocore. With it_q,
one can perform thread-safe enqueing of messages to another thread,
who will receive the related messages triggered via an eventfd

Writing a configuration that will be rejected by the VTY parser
is not the best solution, but still better than printing values
from previous iterations or the stack garbage. In any case,
this is unlikely to happen, just making Coverity happy.

In 'struct gsmtap_hdr' field 'snr_db' is defined as a signed integer,
however all functions that fill this structure accept an unsigned
integer. This is wrong, because SNR can be negative.
Let's use 'int8_t' instead of 'uint8_t'. Changing from unsigned
to signed should be relatively safe compared to the opposite.
Most of the callers I am aware of always do pass 0 anyway.

We used to suppress/drop any "zero length" messages, but we didn't
include the header when computing the length. However, in CBSP there
are messages (at least KEEP-ALIVE-COMPLETE) which only consist of the
header without any information elements. We cannot simply drop such
messages.
This also fixes the return value of osmo_cbsp_recv_buffered() to be
the total number of received octets (including the header).
