Unfortunately "-std=c99" is not sufficient to make gcc ignore cold that
uses constructs of earlier C standards, which were abandoned in C99.

Those are similar to existing *msgb_alloc*() functions but allows
to change the size of destination msgb provided it fits the
data from source msgb.

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.

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.
Change-Id: I580fe99c01bc0a844d877994ec6cd954310e265d
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.

The new functions accept an additional mode_id poiner, which is
currently set for the following frames: AFS_ONSET, AHS_ONSET,
AHS_SID_FIRST_P2 with N * 16 - M bit pattern.
Also, the new API accepts soft-bits instead of hard-bits.
Converting bits from soft to hard is now performed internally.

The initially merged IuUP API and implementation assumed that RFCI with
ID was always in the position of its ID inside the list of RFCIs. This
was the case for messages sent by ip.access nano3g as well as our own
osmocom implementation. However it was noticed that other nodes from
other vendors actually use other order, as allowed by the IuUP message
format.
Hence, we need to break the assumption and provide explicit ID
information in the list.
NOTICE: This commit breaks API and ABI compatibility with older versions
of libosmogsm, but not with any previous release of libosmocore since
the API is only available in master so far (it was added in
9fe1f9fb0b).
Similary, it's only user (osmo-mgw) only uses the API in master, so
there's no API breakage with older releases.

In many cases, a lot of the counters are zero, and we're likely
not interested in those, but only the non-zero counters. Add a version
of the 'show stats' command which dumps only those items with a non-zero
total value.

It was recently found that several IEs which were added in the header
file were not actually added to the tlv_definition, and hence the tlv
parser failed to decode them. Let's make sure we don't foget to add new

There are cases where we want to be notified of a successful BVC reset,
e.g. for a signalling because we can then start resetting the PtP-BVCs.
With this hook it's now possible to do that.

Whenever iterating over a list and removing entries,
llist_for_each_entry_safe must be used instead of llist_for_each_entry.
The comment with "non-consecutive(!)" entries sounds like this is not
needed as long as one is iterating over the list consecutively. I guess
that might have worked with prefetch logic, however the prefetch
function is just a stub in linuxlist.h. (Also prefetch has been removed
from list.h in linux.git e66eed651fd18a961f11cda62f3b5286c8cc4f9f.)

Those are available in 3GPP TS 48.008 version 16.0.0 Release 16, section
3.2.2.17 Cell Identifier. It can be seen that we have a collision
between the osmocom non-standard format and the SAI standard one.
This is because CGI-PS is not really a TS 48.008 Cell Identifier, but only
specified in TS 48.018 and has no ID number assigned. The CGI-PS was
added there because the whole osmo-bsc neighbour configuration works
with CellIds to manage neighbours, so it felt natural to extend the APIs
to also provide means to use CGI-PS format (TS 48.018 even refers 48.008
existance and mentions there's no explicit ID).
At the time this Cell Identifier was added, the firstly available number
(11) was taken, which was of course a really bad idea since newer
versions of the spec can at some point use it, which is the case if one
checks for instance TS 48.008 Release 16 SAI Cell Id.
There no perfect way to fix this bad decision at the time, but the
CGI-PS is only used in osmo-bsc and only for RIM related purposes, so by
changing the ID of CELL_IDENT_WHOLE_GLOBAL_PS, we only break RIM under
some specific CIs being used, and when an osmo-bsc is built against
older libosmocore and then used at runtime against a newer libosmocore
(which should be rare).
Hence, the downside is acceptable, and by moving the new ID number to be
ouside of the spec proto TS 48.008 range (4 bits), we make sure we don't
have the same problem again in the future.

These macros are built on top of the __builtin_expect() function [1],
which provides the compiler with branch prediction information.
Similar macros exist in the Linux kernel: likely() / unlikely().

There already are osmo_quote_str_buf() and osmo_quote_str_buf2(), same
for _escape_, but none of them return the snprintf() like string length.
A private function does, publish this in the API.
The returned chars_needed is required to accurately allocate sufficient
size in string functions that call osmo_quote_str/osmo_escape_str. I am
adding such in osmo-upf.git.
