codec: new functions osmo_{fr,efr}_sid_reset()

In Iec5c1f2619a82499f61cb3e5a7cd03ff0f020ad8 we added
osmo_{fr,efr}_sid_preen() functions that apply SID classification
of GSM 06.31/06.81 section 6.1.1 (osmo_{fr,efr}_sid_classify()),
reject invalid SID, and "rejuvenate" deemed-valid SID frames by
resetting their SID code word, correcting the one bit error that
may be present in a deemed-valid SID frame.  However, the last
operation (rejuvenation of a SID frame by resetting its SID field)
should also be made available as its own function, as it may be
more efficient in some applications: for example, an application
may need to call osmo_{fr,efr}_sid_classify(), apply the rejuvenation
to valid SID, but also use the classification result to drive other
logic.  Factor out these functions.

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
