We are mixing enums and hope that no short-enums are used. This
is leading to a lot compiler warnings generated by clang. Change
the API to work with integers.
Porting:
The go_parent_cb implementations in the applications need to be
fixed. The API change leads to a compile time warning.
Fixes:

different enumeration type 'enum node_type' [-Wenum-conversion]

For some reason the structure is closer to be a LV (length
and value). The value is actually a tag but it is counted
inside the length. Introduce an overload of the parse function
to provide an offset for the length. This will be taken from
the returned length.
The current functions are used to 'qualify' an APN from the
user-supplied APN name (name identifier) towards the fully-qualified
APN name which is used in the .grps DNS zone.
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.

The cast is not present in the original macro and was added
in OpenBSC with commit (be68f6fc6cde1367a4481d2e774a64e2cd657267)
to help using the header with C++. Due the recent issue in
the bssgp flow control code, let's remove the cast to see
wrong pointer usage. In case C++ code doesn't compile anymore
we can see how to add a cast back to it.
Change was proposed by Michael McTernan
In OSX the int declares linkage and for libosmo-abis we have
two static asserts with the same name in two different compilation
units. When adding the "unused" attribute I removed the typedef.
I verified with a gcc 4.9.2 that no new warnings will be shown
when compiling libosmo-abis.
Currently the return value of the gprs_ns_tx family of functions is
often ignored. This is not a serious issue, since the successful
delivery of the messages is neither guaranteed nor acknowledged by
the network layer anyway.
Nevertheless this commit adds logging (level INFO) to gprs_ns_tx and
gprs_ns_msgb_alloc. The definition of the latter has been moved from
the header file to gprs_ns.c.

On GNU __BYTE_ORDER and __LITTLE_ENDIAN is defined and
the include is "endian.h" on FreeBSD it is "sys/endian.h"
and LITTLE_ENDIAN/_LITTLE_ENDIAN and BYTE_ORDER/_BYTE_ORDER
is defined.
Create a header file that defines OSMO_IS_LITTLE_ENDIAN
and OSMO_IS_BIG_ENDIAN and can be used as
#if OSMO_IS_LITTLE_ENDIAN
do_little_endian
#elif OSMO_IS_BIG_ENDIAN
do_big_endian
#else
#error "Unknown endian"
#endif
Currently incoming BSSGP STATUS messages are just logged and no other
action is taken. This makes it impossible for higher layers to react
to failures which are indicated by corresponding STATUS messages
unless a timeout is triggered as a result of that failure later on.
This commit adds a bssgp_rx_status() function and calls it on
incoming STATUS messages. That function logs a message, increments the
new BSSGP_CTR_STATUS counter if the bctx context exists and invokes
an NM_STATUS status indication. The latter will allow the application
to handle failures immediately. Since all STATUS messages should be
handled, the function is already called in bssgp_rcvmsg and the
message is no longer handled in (and will not reach) bssgp_rx_sign
and bssgp_rx_ptp.

These patches enhance the Supplementary Service (SS) processing from
only being able to handle USSD to other SS, specifically activation,
deactivation and interrogation of those SS. Registration is not yet
implemented.
include/osmocom/gsm/protocol/gsm_09_02.h has been added with needed
values for SS.
Modified by Harald Welte to keep the old ussd-only functiosn for API/ABI
stability.
A pointer to struct osmo_fd is used in a few prototypes declared in
gsm/ipa.h, but is neither declared explicitly nor is such a
declaration reachable via the given include directives.
This patch adds a forward declaration of this type to ensure proper
compilation.

We want to see from which category/subsystem a certain log message
is coming from and use a different timestamp format as well. Add
two new bitfields. This doesn't change the size of the structure
and on 32bit we still have 27bits left.
The extended timestamp will take preference over the current and
default timestamp format.
Fixes: SYS#602
For the BSC/NITB application we see that people modify the band
without modifying the ARFCN. This creates an unbootable config.
Using the new hook the BSC/NITB can check if the config is
consistent and prevent the config file being written.

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.
Currently gprs_nsvc_reset does not return any value.
This patch changes the function to return an integer, where a value
less than zero indicates an error. The value is taken from the
gprs_ns_tx_reset function. In case of failure, an error message is logged.
