add gsm23236: MSC pooling: TMSI and NRI utility functions
These utilities will be used by osmo-bsc to determine the Network Resource
Indicator seen in the TMSI, and (potentially) by osmo-msc to compose a TMSI
with a specific NRI, for osmo-bsc's load balancing between several MSCs.
Add utility functions to:
- extract an NRI value from a TMSI.
- overwrite the NRI value in a TMSI.
- limit an NRI in a (random) TMSI to a given list of ranges.
- add NRI value ranges to a list.
- remove them from a list.
- match NRI value (range) to a list.
- parse NRI values from string, for VTY.
- common VTY functionality of adding/removing NRI values from argv.
Add C tests for the above.
Why we need public API for NRI ranges: In osmo-bsc alone, we need the same NRI
API twice, 1: to manage/list NRI value ranges per-MSC, and 2: to manage/list
NULL-NRI values. If we also consider (potentially) adding NRI support to
osmo-msc, we need the same API twice again there. Hence it is useful to define
re-used API up here in libosmocore.
