Add a standalone bcd-to-string conversion function with generic parameters.
Add a regression test in utils_test.c.
So far there is no single universal implementation that converts a BCD to a
string. I could only find gsm48_mi_to_string(), which also interprets
surrounding bytes, MI type and TMSI as non-BCD value.
The idea is to use this function from gsm48_mi_to_string() and similar
implementations in subsequent commits.
Root cause: in osmo-msc, I want to have an alternative MI-to-string function
for composing an FSM name, which needs the BCD part of gsm48_mi_to_string() but
not the TMSI part.

At the moment the all gsm0808 cause codes are encoded directly using the
tlv API directly to put a one byte TLV field. This works ok for most
situations where the cause code consists of a single byte. However,
gsm0808 specifies a two byte cause code model where cause codes may be
extended up to two bytes. Instead of implementing the encoding over and
over and again, let's rather have an encoder function we can call.
- Add an encoder function that can generate single byte and extended
cause codeds and makes the length decision automatically.
- Use only this function to append cause codes

It's similar to osmo_sockaddr_to_str_and_uint() but does not require odd
typecasting for AF_INET case. Make osmo_sockaddr_to_str_and_uint() into
wrapper around new function and make sure to check for address family
before typecasting. Also use proper return type.

ARFCNs are values in well defined ranges. Until this patch, ARFCNs not
belonging to any band were blindly assigned to DCS1800 by
gsm_arfcn2band, causing unnoticed bugs and misconfigurations in
osmo-bsc.
Previous API gsm_arfcn2band cannot accomodate this kind of check easily,
so let's deprecate it to tell people to use a new API gsm_arfcn2band_rc
which performs this kind of checks and allows callers to log failures,
misconfigurations, etc.
At the same time, modify implementation of gsm_arfcn2band to abort if an
invalid ARFCN is passed, this way users of this API can notice they are
passing wrong data to it that most probably will produce unexpected
results.

In gprs_ns_process_msg(), we were dispatching the S_NS_UNBLOCK
signal before sending out the NS_POUT_UNBLOCK_ACK message.
Signal handlers might send messages to the other side, assuming
that NS is now unblocked. However, since such messages will arrive
before the UNBLOCK_ACK message the receiver might discard them.
This problem has been observed with our TTCN3 BSSGP_Emulation
as a peer to osmo-pcu.
This patch makes TTCN3 PCU TC_paging() test pass regardless of
whether the test or osmo-pcu is started first. Before this patch,
this test would only pass if the test was started before osmo-pcu.
A remaining problem is that the test does not yet keep passing
reliably unless osmo-pcu is restarted between test runs.

Show each rate counter group's index in the output of the
'show rate-counters' command, to provide some way of telling
apart distinct instances of the same rate counter group.
This is not a very user-friendly UI because these indices are
generated internally by libosmocore and/or applications, so
users cannot easily assign meaning to these indices. However,
the current rate counter implementation doesn't allow for more.

only one known caller, which is updated in this commit).
Note that printing of the group title was an undocumented feature.

When sending a statsd metric we need to specify a type which can be a
"g"auge, "c"ounter, "t"imer, "h"istogram, and "m"eter.
We used to just pass the stat_item unit into this field, but that is the

Change the type field so stat_items are sent as "g"auges. Note that
negative values don't seem to be supported by statsd.

3GPP_TS_48.008, 3.2.2.103 Speech Codec List states the following:
"The length indicator (octet 2) is a binary number indicating the
absolute length of the contents after the length indicator.
The length depends on the number and type of Speech Codec Elements
to be included. The minimum length of one Speech Codec Element is 1
octet and the maximum length is 3 octets. The maximum number of
Speech Codec Elements within the Speech Codec List is not defined."
This clearly refers only to the length of a single speech codec
element but not on the overall list. So speech codec lists with
length 0 are indeed permitted by the spec.
- Remove the assertion that checks on zero length speech codec
lists.

During 'show online help', the XML vty node dump, omit all commands marked
HIDDEN.
These commands were already hidden from the VTY reference prior to commit
I1f18e0e41da4772d092d71261b9e489dc1598923, because of broken/confusing bit and
boolean logic mixup. After that commit, HIDDEN commands end up in the doc. So
practically, this patch here brings back the status quo of before above commit,
even though the previous code clearly "intended" to list HIDDEN commands in the
reference but failed to have that effect.
AFAICT the complete list of commands currently hidden is:
* osmo-bsc: bts/"training_sequence_code <0-7>",
* osmo-bsc: ts/"phys_chan_config PCHAN" for uppercase pchans;
* osmo-bts: bts/"rtp bind-ip A.B.C.D" which actually says
vty_out(vty, "%% rtp bind-ip is now deprecated%s", VTY_NEWLINE);
* osmo-sgsn: 'reset sgsn state' used for SGSN testing.
Note that the osmo-sgsn build was broken by including hidden commands in the
vty reference, since one of its hidden commands had missing doc strings and
made osmotestconfig.py signal failure. This would fix that from the
hide-hidden-commands angle, and so would osmo-sgsn commit
I8b6e8615e409266910f2f76a10ced9ab33e4de91 from the fix-the-doc-strings angle.

In vty_dump_nodes(), make sure the bitwise & is evaluated first.
For the deprecation flag (0x1), the practical effect is most likely identical,
