Neels Hofmeyr c36e2e4924 fix osmo_escape_str_c() and osmo_quote_str_c() 
The osmo_escape_str_c() and osmo_quote_str_c() functions return truncated
results when characters need escaping. For example:

  osmo_quote_str_c(NULL, "foo"); --> "foo"
  osmo_quote_str_c(NULL, "foo\n"); --> "foo\n
  osmo_quote_str_c(NULL, "foo\tbar\t\n"); --> "foo\tbar\t

Implement these _c variants using OSMO_NAME_C_IMPL() to always allocate
sufficient memory.

However, current osmo_escape_str_buf2() and osmo_quote_str_buf2() fail to
return the required buffer size (even though that information is readily
avaiable), so these don't qualify for accurate use of OSMO_NAME_C_IMPL().

Hence, move the implementations of osmo_escape_str and osmo_quote_str to an
internal static function that returns the characters needed, so that all
dynamically allocating implementations can return un-truncated results.

Of course, external callers would also benefit from escape/quote API that
accurately returns the amount of characters needed, but I am not changing
public API in this patch, on purpose, ... yet.

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 libosmcoore.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
  • libosmotrau contains encoding/decoding functions for A-bis TRAU frames
