Even if ./configure --disable-doxygen was passed and doxygen builds are by
default skipped, provide a manual 'make apidoc' target that nevertheless
generates the API doc on the premise that a 'doxygen' program is available.
Especially since we do a two-pass doxygen build whenever any source file
changes, my guess is --disable-doxygen could be a common choice. It is then
cumbersome to have to ./configure just to get one doxygen build started.

So far, when modifying a source file, the doxygen docs were not regenerated
automatically. It required a manual 'rm -rf docs/core' or similar. Make it
rebuild automatically:
Add each library's source files to the list of dependencies for the first-pass
doxygen build.
Attention, since all libraries depend on the .map files of each other library,
and each library depends on its own source files, that means that a single
touch on one .c file anywhere will result in rebuilding the entire doxygen
docs. It is correct to do so, since any file may introduce \ref targets used
anywhere else. If you don't want that, --disable-doxygen.

doxygen \ref cross-references to groups or files from other libraries only work
when the .map file was present when the HTML was generated, and when that .map
file was listed in TAGFILES in the Doxyfile.
- Makefile.am: introduce a two-pass build for doxygen API docs.
- First build pass makes sure the .tag files are present.
- Second build pass picks up all the references, hence generates hyperlinks
properly.
- Add all libraries to TAGFILES of all other libraries, so we can from now on
freely criss-cross reference from everywhere to everywhere.
- Add all libraries' tag files as dependencies for all others.
Example: in upcoming tdef.h, I would like to cross reference to tdef_vty.h, and
vice versa, even though they are in libosmocore and libosmovty, respectively.
This is now possible.
We may still need to fix some problems with naming collisions, see for example
stats.h, which exists twice with identical doxygen handle (different source
dirs seems to not suffice for doxygen).

Remove any special node exiting from the VTY CTRL-C handling.
From a curious VTY transcript test glitch, I noticed weird behavior by the VTY
telnet shell: usually, when the user hits CTRL-C, that means to cancel the
current command line and present a fresh, clean prompt. However, only on the
CONFIG_NODE and CFG_LOG_NODE, a CTRL-C also exits the current node and moves up
by one level. This behavior is unexplainable and makes zero sense.
No other nodes exit on CTRL-C:
- on the ENABLE node, a CTRL-C stays on the ENABLE_NODE and doesn't exit to the
VIEW_NODE.
- any sub-nodes of the CONFIG_NODE stay unchanged, e.g. 'network' or 'bts' /
'trx', etc.
There is no apparent special meaning of CTRL-C on CONFIG_NODE nor CFG_LOG_NODE
to justify this odd choice.
Particularly, the vty transcript tests using osmo_verify_transcript_vty.py rely
on sending CTRL-C to clear the command prompt, so that we can properly test
sending '?' to the VTY during transcripts. In a live session, a '?' prints
available options and then updates the prompt with identical command arguments.
In a transcript test, that doesn't make sense, because each time the transcript
writes out a new command to run. Consider e.g. a transcript test like:
tdef_vty_test(config)# timer ?
tea Tea time
test Test timers
software Typical software development cycle
tdef_vty_test(config)# timer tea ?
[TNNNN] T-number, optionally preceded by 't' or 'T'.
To be able to issue a fresh command after '?', osmo_verify_transcript_vty.py
explicitly sends a CTRL-C to clear the command buffer. Hence there we rely on
predictable behavior of CTRL-C.
More particularly, the upcoming osmo_tdef_vty transcript tests are apparently
the first that want to test '?' behavior on the CONFIG_NODE's root level and
fall on their face, because of the implicit exit that happens only there.

Since very recently we sensibly handle commands like
cmd ([one]|[two]|[three])
as optional multi-choice arguments. In addition, support the more obvious
syntax of
cmd [(one|two|three)]
Internally, the tokens are mangled to [one] [two] and [three], which is how the
rest of the code detects optional args, and makes sense in terms of UI:
> cmd ?
[one]
[two]
[three]
(i.e. optional arguments are always shown in braces in '?' listings)
Before this patch, commands defined with a syntax like [(one|two)], would lead
to an assertion (shows as "multiple") during program startup.

Add basic optional multi-choice argument support.
The VTY detects optional arguments by square braces.
> cmd ?
[optional-arg]
> cmd optional-arg
ok
> cmd
ok
However, within multi-choice args, these braces were so far not treated as
optional:
> list
cmd2 ([one]|[two]|[three])
> cmd2
% Command incomplete
In preparation for I952b3c00f97e2447f2308b0ec6f5f1714692b5b2 which will enable
the more obvious syntax of
cmd [(one|two)]
for reasons of internal implementation, first support a syntax of
cmd ([one]|[two])
The internal vty implementation always needs square braces around each option.
There is currently no good way to prevent developers from defining braces
inside multi-arguments, so it is easiest to allow and handle them:
> list
cmd2 ([one]|[two]|[three])
> cmd2
ok
The VTY doesn't guard against a mix like
cmd (one|[two])
With this patch, a multi-choice command is treated as optional iff the first
element is in square brackets. The remaining elements' square brackets have no
effect besides confusing the user. This is not explicitly checked against.
In general, I would prefer to check all of these details, but the current VTY
code with its endless code duplication and obscure string mangling just doesn't
provide that luxury. There are numerous worse errors hidden in there.

Replace osmo_gsup_get_err_msg_type() with a wrapper to
OSMO_GSUP_TO_MSGT_ERROR(). This macro assumes, that all error messages
are (request message | 0x000001). Add a big comment header for
osmo_gsup_message_type, describing this already implicitly followed rule
and therefore making it explicit.
With this change, we don't need to maintain the request -> error message
mapping in osmo_gsup_get_err_msg_type() anymore.

During testing of the upcoming tdef API, it became apparent that passing very
large timeout values to osmo_fsm_inst_state_chg() wraps back in the number
range, and might actually result in effectively very short timeouts instead.
Since time_t's range is not well defined across platforms, use a reasonable
maximum value of signed 32 bit integer. Hence this will be safe at least on
systems with an int32_t for struct timeval.tv_sec and larger.
Clamp the osmo_fsm_inst_state_chg() timeout_secs argument to a maximum of
0x7fffffff, which amounts to just above 68 years:
float(0x7fffffff) / (60. * 60 * 24 * 365.25) = 68.04965038532715
(In upcoming patch Ibd6b1ed7f1bd6e1f2e0fde53352055a4468f23e5, this can be
verified to work by invoking tdef_test manually with a cmdline argument passed
to enable the range check.)

Before this patch, if timeout_secs == 0 was passed to
osmo_fsm_inst_state_chg(), the previous T value remained set in the
osmo_fsm_inst->T.
For example:
osmo_fsm_inst_state_chg(fi, ST_X, 23, 42);
// timer == 23 seconds; fi->T == 42
osmo_fsm_inst_state_chg(fi, ST_Y, 0, 0);
// no timer; fi->T == 42!
Instead, always set to the T value passed to osmo_fsm_inst_state_chg().
Adjust osmo_fsm_inst_state_chg() API doc; need to rephrase to accurately
describe the otherwise unchanged behaviour independently from T.
Verify in fsm_test.c.
Rationale: it is confusing to have a T number remaining from some past state,
especially since the user explicitly passed a T number to
osmo_fsm_inst_state_chg(). (Usually we are passing timeout_secs=0, T=0).
I first thought this behavior was introduced with
osmo_fsm_inst_state_chg_keep_timer(), but in fact osmo_fsm_inst_state_chg()
behaved this way from the start.
This shows up in the C test for the upcoming tdef API, where the test result
printout was showing some past T value sticking around after FSM state
transitions. After this patch, there will be no such confusion.

Add osmo_hexdump_buf() as an all-purpose hexdump function, which all other
osmo_hexdump_*() implementations now call. It absorbs the static
_osmo_hexdump(). Add tests for osmo_hexdump_buf().
Rationale: recently during patch review, a situation came up where two hexdumps
in a single printf would have been useful. Now I've faced a similar situation
again, in ongoing development. So I decided it is time to provide this API.
The traditional osmo_hexdump() API returns a non-const char*, which should
probably have been a const instead. Particularly this new function may return a
string constant "" if the buf is NULL or empty, so return const char*. That is
why the older implementations calling osmo_hexdump_buf() separately return the
buffer instead of the const return value directly.

Add
* osmo_lai_cmp() (to use in gsm0808_cell_id_u_matches())
* osmo_cgi_cmp() (to use in gsm0808_cell_id_u_matches())
* gsm0808_cell_id_u_match() (to re-use for single IDs and lists)
* gsm0808_cell_ids_match()
* gsm0808_cell_id_matches_list()
* Unit tests in gsm0808_test.c
Rationale:
For inter-BSC handover, it is interesting to find matches between *differing*
Cell Identity kinds. For example, if a cell as CGI 23-42-3-5, and a HO for
LAC-CI 3-5 should be handled, we need to see the match.
This is most interesting for osmo-msc, i.e. to direct the BSSMAP Handover
Request towards the correct BSC or MSC.
It is also interesting for osmo-bsc's VTY interface, to be able to manage
cells' neighbors and to trigger manual handovers by various Cell Identity
handles, as the user would expect them.

Where "130" seems to be the maximum value of uint8_t, shifted right one +

gsm48_generate_mid() doesn't help and gcc still insists there is a problem :(

This resolves an issue introduced in 84fb5bb6a09a6a358f98c654c84c3b99a0f24eef
when msgb_wrap_with_TL() was introduced as an inline function with

*MUST* always be renamed. This has been the case for almost a decade

As part of fixing issue OS#3075, we want to migrate support
for encoding system information from osmo-bsc to libosmocore.
This change ports osmo-bsc code for encoding SI rest octets.
The conversion was a bit tricky in some places because some
functions receive a 'struct gsm_bts' parameter in osmo-bsc.
In this libosmocore version, such functions expect parameters
which correspond to the individual fields of 'struct gsm_bts'
which are used by these functions.
Several structs from osmo-bsc's system_information.h are now
also declared in libosmocore headers, with an added osmo_ prefix
to avoid collisions with existing definitions in osmo-bsc.
Some helpers were ported from osmo-bsc's system_information.c
to libosmocore's gsm48_rest_octets.c. Contrary to osmo-bsc's
implementation they are now only visible within this file.
Unfortunately, this code ported from osmo-bsc lacks unit tests.

Note that OSMO_GSUP_IMEI_RESULT_ACK is 0 on the wire, although the

I had implemented enum osmo_gsup_imei_result after
enum osmo_gsup_cancel_type above, where this comment exists as well,
and I incorrectly assumed that enum osmo_gsup_cn_domain in the middle
was also implemented this way and therefore adding the comments to each
