gsm0503_tch_hr_decode2(): new function, emits TS101318 format

The original design of gsm0503_tch_hr_{en,de}code() functions contains
a mistake in that a pseudo-RFC5993 format was chosen for HR codec frame
input and output, instead of "pure" (agnostic to outer RTP encoding)
form of 14 bytes.  We would like to change this design so that we can
feed pure 14-byte HR codec frames to the channel coding function and
get such frames back from the channel decoding function - however,
we cannot break libosmocoding API for existing users.  In the decoding
direction, create a new function that emits TS 101 318 format, and
turn the legacy gsm0503_tch_hr_decode() API into a wrapper function
for backward compatibility.

libosmocore - set of Osmocom core libraries

This repository contains a set of C-language libraries that form the core infrastructure of many Osmocom Open Source Mobile Communications projects.

Historically, a lot of this code was developed as part of the OpenBSC project, but which are of a more generic nature and thus useful to (at least) other programs that we develop in the sphere of Free Software / Open Source mobile communications.

There is no clear scope of it. We simply move all shared code between the various Osmocom projects in this library to avoid code duplication.

The libosmocore.git repository build multiple libraries:

  • libosmocore contains some general-purpose functions like select-loop abstraction, message buffers, timers, linked lists
  • libosmovty contains routines related to the interactive command-line interface called VTY
  • libosmogsm contains definitions and helper code related to GSM protocols
  • libosmoctrl contains a shared implementation of the Osmocom control interface
  • libosmogb contains an implementation of the Gb interface with its NS/BSSGP protocols
  • libosmocodec contains an implementation of GSM voice codecs
  • libosmocoding contains an implementation of GSM channel coding
  • libosmosim contains infrastructure to interface SIM/UICC/USIM cards
