Remove the paragraph about writing to the Free Software Foundation's
mailing address. The FSF has changed addresses in the past, and may do
so again. In 2021 this is not useful, let's rather have a bit less
boilerplate at the start of source files.

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.
