The macro msgb_sms() is basically an alias for msgb_l4(). Lets use
msgb_l4() in msgb_l4len() instead of msgb_sms().

When any of l1h, l2h, l2h or l4h is set to NULL (which is the default
for newly allocated message buffers). Then the msgb_lXhlen() functions
will return the address value of msgb->tail. This can lead to unexpected
results at a later point. We should have an OSMO_ASSERT to catch the
problem early.

This makes it possible to pass expressions to the abovementioned
macros without any side-effects. Strictly speaking, this is only
necessary for argument 'b' of GSM_TDMA_FN_SUB, but let's also add
them to GSM_TDMA_FN_SUM for consistency.

Ranges can now be specified in hexadecimal notation. In this case, only
hexadecimal values are accepted (prefixed with "0x").
In order to allow using a hexadecimal value as an input argument, the
command must specify the range in hexadecimal form.
This way all existing commands (decimal) won't get an hexadecimal value
unless they are further extended in the future, avoiding hard to notice
breakage due to use of stroul() without using base=0 or even worse,
using atoi() directly (which only understands decimal and provides no
error checking mechanism).
A command argument can be expanded to accept both decimal and hex in a
range by means of specifying both, example:
"mycmd (<0-255>|<0x0-0xff>)".

The errno values are platform dependent. Printing them in the expected
output causes failure on some systems that don't match my development
system.
Still check for match with the expected errno value, but don't print the

The documentation for osmo_use_count_get_put states the return value is
"Negative on range violations or USE_LIST == NULL, the use_cb()'s
return value, or 0 on success"
However, the code in _osmo_use_count_get_put doesn't check if uc is NULL
- instead it would crash in osmo_use_count_find() where it is dereferenced.
Add a check for uc and return -EINVAL if it is NULL.

This reverts commit a4063efa7d.
Reason for revert: It is not possible to guess the IP address
family from uninitialized memory. This function simply glorifies
random noise into an IPv6 address. It makes no sense to have it.

This reverts commit e145e28a91.
Reason for revert:
The function osmo_sockaddr_strs_to_str() should not be part of the
osmo_sockaddr_str API. The implementation of this should live in
the function multiaddr_snprintf() added in patch
Icef53fe4b6e51563d97a1bc48001d67679b3b6e9
and should not use dynamic allocation.

Sometimes we receive generic "struct sockaddr" with unspecified (AF_UNSPEC)
address family. It's handy to try to guess
the proper address (there're just 2 variants ATM in most practical applications).
Use the added function to relax input checks in osmo_sockaddr_str_from_in*()

This is similar to what we already do between BSC<->MSC to pass Osmux
CID (GSM0808_IE_OSMO_OSMUX_CID).
We now want to support Osmux between BSC and Osmocom BTS, hence add an
extension IE which will be used in ipaccess CRCX messages to tell the
BTS to use Osmux.

This feature is used by the BTS to signal to the BSC that it supports
using Osmux instead of RTP on the BTS<->BSC(MGW) data plane.

I was warned by gcc about comparing a pointer with an integer when using
TLVP_PRESENT with something like:
bool expect = ...;
if (expect != TLV_PRESENT(...))
That's indeed dangerous because TLV_PRESENT is considered to return a
boolean, as opposite to TLV_VAL.

This change adds test_state_chg_Ts() and test_state_chg_Tms() checking
state timeout s/ms accuracy when using osmo_fsm_inst_state_chg() and
osmo_fsm_inst_state_chg_ms() calls, respectively.
test_state_chg_Tms() demonstrates that osmo_fsm_inst_state_chg_ms()
is not working as expected: the timeout fires earlier than expected.

The testcase in gsm0408_test is still failing because the encoder
produces a different result (with octet 3a present). There is no
way to tell the encoder to use the implicit coding, and in general
this is not that critical, so we can live with that.

The new testcase contains a Bearer capability IE from Siemens S11E,
which does not use octet 3a (no extension bit set in octet 3).

Currently, if one of the testcases fails, test_bearer_cap() would
abort and skip the remaining testcases. Also, a msgb would not
be free()ed making the LeakSanitizer unhappy.
Instead of returning early, jump to the end of loop to ensure that:
* the verdict ('passed' or 'failed') is always printed,
* all remaining testcases are still executed,
* the msgb is free()ed.

That code path should not happen since this function is only called for
data frames coming with IUUP_FSM_EVT_IUUP_DATA_IND.
Control frames should come with specific events like
IUUP_FSM_EVT_IUUP_CONFIG_REQ.
Hence, let's add an assert to make sure we early exit if that ever
happens (it shouldn't), instead of carrying on reading uninitialized var
"dt".
