Neels Hofmeyr 17518fe393 doxygen: unify use of \file across the board
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).

Neels Hofmeyr 33370cb18d doxygen: various fixes in core/timer.h
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.

Neels Hofmeyr 87e4550585 doxygen: enable AUTOBRIEF, drop \brief
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.

Philipp Maier 4703fd215f cosmetic: remove API documentation strings in header file
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.

Philipp Maier 884ba0f2bc gsm0808: add function gsm0808_speech_codec_from_chan_type()
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.

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.
