Harald Welte 7214a9148e UNTESTED WIP: remove global bssgp_nsi variable
As we can now have several NS instances inside the program, let's
remove the global bsspg_nsi to which BSSGP bound itself.  Rather,
all functions are now parametrized based on the NS Instance that's
either
* explicitly passed to the function (in case no msgb and no bctx), or
* stated in the BVC context / bctx (if any), or
* explicitly given as argument to the function (if no msgb and no bctx)

Harald Welte 8154266457 libosmogb: Support multiple instances also from VTY
The NS code (part of libosmogb) already understands the concept of "NS
instances", and each of those instances can be bound to different IP
addresses with the gprs_ns_nsip_listen() call.

The problem is the VTY code for NS. It is written with a single
global ns-instance in mind. Having a second NS instance thus means that
currently only one of the two would be configurable (or available for
"show..." commands) from the VTY, which is of course of little
usefulness.

This patch addresses this by introducing the concept of "NS instance
numbers" and a global array of a maximum of 256 NS instances. The VTY
commands have been extended as needed.

Vadim Yanitskiy d2d9760c08 utils/conv_gen.py: generate a single file
Instead of generating every convolutional code into a separate
file (such as conv_xcch_gen.c, conv_cs3_gen.c), it is better to
have a single file, containing all definitions, because as many
convolutional codes we add, as many entries we will have to add
into 'src/gsm/Makefile.am'. This approach increases readability
of the Makefile.am, and also makes us able to share some data
between some convolutional code definitions.

For example: xCCH, RACH, SCH, TCH/F, both CS2 and CS3 may use
the same *_state[][2] and *_output[][2] arrays within a single
file. This optimization is currently WIP.

Neels Hofmeyr a95ee5e6e1 fix USSD: SS message type mask should be 0x3f, not 0xbf
See 04.80[1], section 3.4: the highest two bits are used as counter or ignored
and do not contribute to the SS "Miscellaneous message group". Previous mask of
0xbf included the highest bit, fix to 0x3f.

Observed a value of 0xbb that should mean 0x3b="Register" during testing of 3G
USSD requests, which seem to be the first to send a nonzero highest bit to our
code. The erratic mask of 0xbf lead to an unhandled message type of 0xbb.

Neels Hofmeyr f45334be29 msgb: add msgb_talloc_ctx_init(), deprecate msgb_set_talloc_ctx()
So far each and every main() scope creates a msgb talloc context and either
passes it to msgb_set_talloc_ctx() or sets tall_msgb_ctx directly (by defining
it extern first).

Remove some code duplication: add one central function that creates the "msgb"
talloc context for all.

Most users of msgb employ a talloc_named_const(), but osmo-bts uses a
talloc_pool() instead. Offer both ways by means of the pool_size argument, and
for both ways make sure the context is called "msgb".

Suggest that msgb users should move to this new function: deprecate
msgb_set_talloc_ctx(). To be able to do so, include core/defs.h in msgb.h.

There's a tradeoff between hiding the msgb talloc context behind API that tries
to guess all use cases versus avoiding code dup. This patch opts against code
dup and boldly assumes that all future use is covered.

Also, the new function suggests to not access tall_msgb_ctx directly, which can
be considered a style improvement.

It seems that not all main scopes that use msgb actually initialize the msgb
ctx. As a fallback for these, explicitly initialize tall_msgb_ctx to NULL.

avoids copy+pasting a one-line timer_cb function in every FSM.

Also, even if there is a timer_cb, let it have a return value to decide
if the core should terminate after return from timer_cb or not.
