(address) it is going to and where it is comming from.

RIM routing formation structs can contain different variants of address
identifiers, so it is difficult for an API user to pick the _name()
function to generate a human readable string. Lets add
bssgp_rim_ri_name() and bssgp_rim_ri_name_buf() to make printing a
routing identifier easier.

Back in 2018 in I393907b3c9e0cc1145e102328adad0a83ee13a9f Neels
introduced "last" as an optional flag to log the file/line number at the
end of the line, rather than at the end of the header. It seems nobody
has been usingi this feature, or at least never tried to save a related
config file, as there was no code whatsoever that would ever save this
optional "last" flag.

Let's avoid open-coding the printing of log context and rather rely on
log macros to prefix each log line with the relevant context. This
helps log readability, log post processing whether by grep or more
sophisticated tools.

The current version of libosmocore only supports NACC related RIM
application containers. If the parser detects a different application
container it returns with EINVAL. Unfortunately this means that the
caller can not distinguish if there is a lack of support or a real
parsing error.

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...

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

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.
