This was actually discovered by the following compiler warning in
gcc-6.2.0:
CC gprs_bssgp_bss.lo
gprs_bssgp_bss.c: In function ‘bssgp_rx_paging’:
gprs_bssgp_bss.c:544:2: warning: this ‘if’ clause does not guard...
[-Wmisleading-indentation]
if (TLVP_PRESENT(&tp, BSSGP_IE_TMSI) &&
^~
gprs_bssgp_bss.c:548:3: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the ‘if’
*(pinfo->ptmsi) = ntohl(*(uint32_t *)
^
This is an actual bug. If we recevied a BSSGP Paging Request without
P-TMSI, we might crash or report some random memory as P-TMSI to the
caller in the output data structure.

Print string representation of Cause IE and PDU type instead of
numerical value.

Currently the size of the IMSI pointer is used instead of the size of
the talloc'ed buffer.
This commit changes the call to gsm48_mi_to_string to use the same
value that has been used with talloc_zero_size(). The length is
changed to 17 since that value is used for GSM_IMSI_LENGTH in
openbsc.

Currently large values for Bmax default MS get sliced since a uint16_t is
used as the type of the corresponding parameter of bssgp_tx_fc_bvc.
GSM 48.018, 11.3.2 which in turn refers to 11.3.5 specifies a maximum
of 6MB (0xffff * 100).
This commit changes the type to uint32_t to cover the full value
range.

Currently all 2 byte IE of the message are transmitted in the little
endian byte ordering.
This commit adds htons to the encoding expressions.

The copyright holders Harald Welte, Holger Freyther, Andreas Eversberg
and sysmocom - s.f.m.c. GmbH (represented by Holger and Harald) agree
that the license of libosmogb should be GPLv2+ and not AGPLv3+.
The reason the source files stated AGPLv3+ is due to the history, as
they were moved from OpenBSC to libosmocore at the time we needed to use
them from osmo-pcu. It was an oversight back then to not re-license
them accordingly.

.. not sure how we could have missed that so far.

This is a 24bit integer value, and thus we need to encode the three
least significant octets of the network-byte-order 32bit value, not the
three most significant octets.
