It's often handy to compare certain msgb layer to a given array and
print the position where they differ. Add simple pretty-printer and
corresponding L* wrappers.

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

(similar to those we have for GSM0808).

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.

When adding complex TLV structures where length of V is not known in

the Length field so it can be updated once entire Value is added and its
length is known.

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.

3GPP TS 48.008 chapter 3.2.2.103 states that the configuration bits of
OFR_AMR_WB are coded as follows:
"S0, S2, S4 indicates the supported Codec Configurations. S1, S3, S5, S6,
S7 are reserved and coded with zeroes."
The current default setting of 0x3F violates this requirement. Lets set
the "forbidden" settings zu zero and keep only the allowed ones.
