utils: add osmo_str_to_int() and osmo_str_to_int64()

Properly converting a string to an integer while validating against all
possible errors is not trivial. It is a recurring theme in code review,
and there are places in osmo code that do it wrong.
End this by providing a simple API, if for nothing else then as an
example of how to use strol() / strtoul() / strtoll() / strtoull()
in an airtight way.

A subsequent patch, adding stat items to the CTRL interface, uses this
to properly validate indexes in CTRL variables and convert them to int.
