If a FSM doesn't specify any timer_cb, simply terminate the FSM by
default on time-out. This is a reasonable default for most cases, and
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.

The actual code is from OsmoBTS' tch.c by Harald Welte. Add unit tests,
doxygen annotation and extra memory safety check. Those functions are
used in several BTS implementations but seems generic enough to be
generally useful.

AMR frame according to RFC 4867
* those functions are extended version based on code from osmo-bts'

* add corresponding enum types and strings for logging

This is a "flag" day change. Old OpenBSC break with new libosmocore
because suddenly there is the 0x in front. I am afraid we need to
find a better solution here. I think we will need to create a
gsm48_mi_to_string variant that takes a mode parameter to enable the
TMSI mode and deprecate the old method.
Right now we should not break old versions of OpenBSC.
This reverts commit 78ad042f94afd5bf7de477ae634e9d2fdd9c9dc4.

Previously, we traditionally displayed a TMSI in its integer
representation, which is quite unusual in the telecom world.
A TMSI is normally printed as a series of 8 hex digits.

In osmo_auth_3g_from_2g(), also adjust two comment-closing instances to

(The recent addition of osmo_auth_3g_from_2g() raised my attention, and I added

Move those routines from OpenBSC to libosmogsm, so they can be

inside the openbsc repository in the first place. We need to pay more

To integrate with an external event loop (in this case glib) we
need to allow an application to get a filled out fd_set and then
dispatch it. osmo_fds and maxfds are static and I decided to keep
it that way and instead create two routines to fill the fdset and
then one to dispatch the result.
The public header file does not include sys/select.h and we can
compile the library without select, so I didn't want to require
having to include this file, and used void * for the parameter.
Mark the routines as inline to avoid a call from the select
function. I have confirmed that inlining has an effect on x86
using Debian's gcc-4.9.2-10 compiler
