The functional split betweenthe two functions is now that the
first one creates the ID that is used in the word table and
the second one creates the variants. There no longer is a
requirement that the ID is the normalized version. We might
later reintroduce the requirement that a normalized version be available
but it doesn't necessarily need to be through the ID.
The function that creates the ID now gets the full PlaceName. That way
it might take into account attributes that were set by the sanitizers.
Finally rename both functions to something more sane.
This gives the analyzer more flexibility in choosing the normalized
form. In particular, an analyzer creating different variants can choose
the variant that will be used as the canonical form.
Adds a tagger for names by language so that the analyzer of that
language is used. Thus variants are now only applied to names
in the specific language and only tag name tags, no longer to
reference-like tags.
Adds a mandatory section 'analyzer' to the token-analysis entries
which define, which analyser to use. Currently there is exactly
one, generic, which implements the former ICUNameProcessor.
