rate_ctr: Enforce counter (and ctr_group) names are valid identifiers
As rate counters are automatically exposed on the CTRL interface,
we need to make sure they don't contain special characters such as '.'
which are not permitted/supported by CTRL.
In order to be able to run old versions of osmocom programs with
libosmocore versions after this commit, we introduce some special
name mangling: Any '.' in the names are replaced with ':' during
counter group registration, if valid identifiers can be obtained
this way.
