The patch seemed sensible, but introduces a segfault when hitting tab
on the interactive VTY. Reproduction example:
osmo-msc
telnet 127.0.0.1 4254
OsmoMSC> enable <TAB>
So we need to understand what that line of code actually intends to do.
Until then, revert this to avoid the segfault.
The segfault happens at:
Program received signal SIGSEGV, Segmentation fault.

According to

the libraries supposed to be added to *_LDADD or *_LIBADD
while *_LDFLAGS should contain additional libtool linking
flags. Previously we used both. Let's unify this and move all the
libraries into proper automake variable. While at it - also add
libosmocore.la for tests to LDADD since all the tests link against it
anyway.

Sounds stupid, but we actually didn't support hex nibbles in one of

osmo_bcd2char() has always supported both decimal and hex.
However, osmo_char2bcd() use to only implement decimal digits.
With this patch, it also suppots conversion of hex characters from ASCII
to BCD.
This would be relevant in cases where somebdoy would want to use 'code
11', 'code 12' or 'ST' signals in any addresses (SCCP GT e.g.)

In Change-Id Ifc6ac824f5dae9a848bb4a5d067c64a69eb40b56 we introduce

As rate counters are automatically exposed on the CTRL interface,
we need to make sure they don't contain special characters such as '.'
which are not permitted/supported by CTRL.
In order to be able to run old versions of osmocom programs with
libosmocore versions after this commit, we introduce some special
name mangling: Any '.' in the names are replaced with ':' during
counter group registration, if valid identifiers can be obtained
this way.

Change I24e500e132f5c8e8133d35548cb7b4e4552331d0 was merged, but IMHO needs
improvement. Fix these:
- clean the git source tree before each build step, in common prep_build().
- fix indenting inside the build() macros.
- change build() arg to be build_dir, to absorb cleanup steps into build().
- in jenkins.sh, use $ENABLE_SANITIZE as global env, not passed as arg.
- in jenkins.sh, don't do 'make distcheck' twice. It is not necessary to do it
from source tree as well as separately from source tree, since distcheck
already moves to a different build dir.

Combine the C source file name and the string name into the fsm's internal name
token, and use it in most places instead of the plain struct name: osmo-bsc's
new FSMs have identical struct names in each static c context.
Output in a file name that includes all of these more detailed name tokens.
Also parse '(1 << EVENT)' as event names.
Note that besides this patch, there are also some tweaks to the osmo-bsc patch
that improve the fsm-to-dot experience...
- call fsm-to-dot for single files to avoid name conflicts, or rename each
struct as a unique name.
- Add comments for the event name a callback is intended for, so that not all
transitions are interpreted as TEARDOWN (because it is invoked in common
error handling, which causes the script to interpret it as the causing
event). (or change the event-checking if into a switch that names the valid
event and has a default case for all others.)

Add macro to append to a CTRL commands' reply string, ctrl_cmd_reply_printf().
The talloc_asprintf() part of it is generic enough to qualify for a separate
macro, osmo_talloc_asprintf().
The idea is to not have to decide for each bit added to a string whether the
string is already allocated or not, but simply be able to issue printf commands
and let the macro worry about initial allocation or reallocation.
This originally came from osmo-hlr change
I1bd62ae0d4eefde7e1517db15a2155640a1bab58, where it was requested to move this
bit to libosmocore.

When listening for nsip connections is enabled, then every remote
host may send packets. This is useful for an SGSN that serves
multiple PCUs, but contraproductive for a PCU that awaits packets
from a single SGSN.
Add struct members remote_ip, and remote_port to struct gprs_ns_inst,
when set, then the listening end uses connect() to ensure that only
the expected host may send packets.

Old bitvec_set_uint() uses "unsigned int" as input parameter which
length is not guaranteed. It does not allow to specify which bit_value
to set and does not check for incorrect length. Overall this makes it
harder to re-use and more error-prone.
Let's replace it with extended implementation which uses fixed type
length parameters and extra checks. The additional parameter allows
caller to explicitly indicate the need to use L/H instead of 0/1 for bit
vector elements. It's necessary to properly encode some of the messages
from 3GPP TS 44.018, for example §10.5.2.16 IA Rest Octets.
The old function is left for backward compatibility as a tiny wrapper
around new function and will be deprecated in follow-up patches.

Add ctrl_interface_setup_dynip2() to add a node_count parameter, which can be
used to define more ctrl nodes without having to merge a patch to libosmocore.
In consequence, also add ctrl_handle_alloc2(), since
ctrl_interface_setup_dynip() uses ctrl_handle_alloc() to allocate the node
slots, and add node_count param to static ctrl_init().
Passing zero as node_count indicates to use the default of _LAST_CTRL_NODE as
before, i.e. to not define more ctrl nodes. Assert that we never allocate less
than _LAST_CTRL_NODE slots.
The current ctrl_interface_setup_dynip() and ctrl_handle_alloc() become simple
wrappers that pass zero as node_count. Their use is still valid and they do not
need to be deprecated.
The API comment to ctrl_interface_setup_dynip2() explains how to define more
node IDs.
This patch was verified to work by osmo-hlr.git change
I98ee6a06b3aa6a67adb868e0b63b0e04eb42eb50 which adds two node IDs for use by
osmo-hlr only.
Change-Id: I1bd62ae0d4eefde7e1517db15a2155640a1bab58
Similar APIs exist for opstate and availability status.
This patch does not break backward compatibility because osmo-bsc still
requires direct use of the structure in get_string_value().
