This introduces a new flag OSMO_SOCK_F_NO_MCAST_LOOP, which can be used
to disable the looping back of multicast packets transmitted throug this
socket to other local sockets on the machine.
As this looping-back is active by default, a single option to deviate
from the default is deemed sufficient.

This is a convenience helper that will both close a fd, mark it as
closed and unregister it from the event loop abstraction. In most
cases, you probably actually want to use it instead of manually closing
and calling osmo_fd_unregister().

These PRBS sequences are specified in ITU-T O.150. They are typically

The PDP charging characteristics will be returned from the PDP
selection code and be used in the SGSN. It is following the same
approach as the QoS and PDP addr. It is a bit of a pity that we
have to define this in a different project.

Add deprecation notice for public API use: it shouldn't be used outside

These fields can be in the ISD and the PDP Context inofmration. Store
pointers to this IE in both cases. It needs to be used by the SGSN
when opening a PDP context.

Recent commit 3149b0d076 adds function
gsm0808_chan_type_to_speech_codec() but adds a completely mismatching name in
libosmogsm.map, as well as a definition with a typo in the name.
Fix the entry in libosmogsm.map.
Add the missing 'c' in gsm0808_utils.h

Considering the various styles and implications found in the sources, edit
scores of files to follow the same API doc guidelines around the doxygen
grouping and the \file tag.
Many files now show a short description in the generated API doc that was so
far only available as C comment.
The guidelines and reasoning behind it is documented at
https://osmocom.org/projects/cellular-infrastructure/wiki/Guidelines_for_API_documentation
In some instances, remove file comments and add to the corresponding group
instead, to be shared among several files (e.g. bitvec).

Move a longish comment to the timer group so that it appears in the API doc.
Un-doxygen some floating comments that were associated with unrelated code
items ('/**' --> '/*').
Add braces to some function names so that the API doc will render as reference
links.

Especially for short descriptions, it is annoying to have to type \brief for
every single API doc.
Drop all \brief and enable the AUTOBRIEF feature of doxygen, which always takes
the first sentence of an API doc as the brief description.

Typically we don't place comments with the function declarations
in .h files. Not sure why this file has comments for each. The
API doc belongs in the .c file as proper doxygen comments,
and shouldn't be duplicated in the .h file.
In this particular case, doxygen comments are added in the
corresponding c file recently.

The contents of the speech codec element (struct gsm0808_speech_codec),
that is also used in the speech codec list element (struct
gsm0808_speech_codec_list) can be generated directly from the
permitted speech parameter in the channel type field (struct
gsm0808_channel_type) when full AoIP with compressed speech via
RTP/UDP/IP is assumed and when the codec configuration on the air
interface exactly matches the codec configuration on the IP backhaul.
This patch adds a function that can be used as a helper to fill
out spech codec fields by only giving a permitted speech parameter
as input.
Change-Id: I257c972e9fdf0dfe940a8d483447085bd62e50a2
The permitted speech field used in channel type element (struct
gsm0808_channel_type) uses a different representation as
the type field in the speech codec element (struct
gsm0808_speech_codec)
This patch adds a function to convert from permitted speech to
speech codec type.
Change-Id: Ib26a9c20864459b2baaa04f49b6e7902ba44b7cb
In an AoIP scenario, the speech codec list field specifies the
codecs used in the RTP interface. This patch adds a table
with default codec configurations that match the codec
configurations that are also used on the air interface.

The codec type to be set in member type in struct gsm0808_speech_codec
has its own coding scheme to reference the used codec types. This patch
declares an enum with valid speech codec types.

It's universally useful so it make sense to have it in the shared core:
* move macro from libosmocoding to libosmocore
* add OSMO_ prefix
* add doxygen docs

A warning was printed even if the deprecation didn't apply to
libosmocore because it is still allowed to use it internally.
This patch fixes this case while still printing a warning if external
projects build using libosmocore headers.

It's a pity that even with this patch we still are fare away from having
the whole API documented. However, at least we have a more solid
foundation. Updates not only extend the documentation, but also make
sure it is rendered properly in the doxygen HTML.

It is generally our coding style to mark pointers to constant input data

adhering to this, so let's bring it into compliance.

We cannot assume a certain UART API like uart_baudrate() which only
exists in OsmocomBB. Rather, use generic function prototypes
(sercomm_drv_*) which are to be provided by the application /
environment to the sercomm core.

osmo_sercomm_{bind,get}_uart() are not really needed anymore, as
sercomm_inst is public and thus the user can access the uart_id member
directly.

Those values are not relevant to the sercomm user, only to the
implementation and thus can remain inside sercomm.c

This imports the file src/target/firmware/comm/sercomm.c from
