Neels Hofmeyr 923cb84270 vty 'stats reset': do not reset stat_items 
Exempt all stat_item statistics from 'stats reset'. Only reset rate_ctr
statistics to zero.

The rate_ctr statistics have an implicit time scale, counting occurences
per time unit. For them it makes sense to reset all ratings and start
from zero, for example in a test suite (e.g. our TTCN3 BSC_Tests).

In contrast, stat_item statistics count number of objects or nr of
specific object stati at any given time, and they do not deteriorate
over time. Many stat items depend on increment/decrement to be sane.

For example, in osmo-bsc, if the nr of connected BTS is 3, that does not
make sense to be reset to zero. There are still 3 BTS connected, only
the stat_item would suddenly reflect zero. From then on, it'd be wrong.

All stat_items are by definition wrong after a 'stats reset'.
- Those that depend on increment/decrement will be wrong until the
  program exits, and
- those that are set to absolute values will be wrong up until the next
  value is set. That could be seconds or hours later, depending.

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
