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).

recently, where it moved to use this function from libosmocore and
errors started to show up in TTCN3 tests.

We must always send the RELEASE.{indication,confirm} last before
returning from a function. We cannot rely on the datalink to
still be around after the call, as the SAP user might have destroyed
the data link meanwhile.
This fixes a heap use-after-free (at least) with RBS2000 when the BTS
is fully brought up and the OML data link is lost, see OS#1762

This use of strncpy() fails to account for the terminating nul
character. Use OSMO_STRLCPY_ARRAY() instead.
(Interestingly my compiler doesn't complain about this one, though it
failed on another similar use of strncpy().)

My gcc (Debian 8.3.0-6) 8.3.0 refuses to build this strncpy() use: it
issues the buffer length as n and thus potentially fails to account for
the terminating nul. The line after that fixes the problem, so it's not
an actual bug. Anyway, we have a policy to never use strncpy(), and have
osmo_strlcpy() and OSMO_STRLCPY_ARRAY() for this.
This strncpy() was introduced last month during first addition of
gprs_ns2_fr.c:

In case the first bind is not working the SNS would never build a

using an offset.
Instead of tracking the binds use an offset instead of a direct pointer.
This might result in skipping the order of the next bind.
