8366e4ca83 penalize search with frequent partials 
Avoid search against frequent partials if we have already looked for
the full name equivalents.

283db76e45 avoid splitting of first token when a housenumber is present 
This only covers the case of <poi name> <street name> <housenumber>
which is exceedingly rare.

8a36ed4f6f increase threshold for full name searches 
They still should be preferrred over expensive partial name searches.

d0f45155c8 fix search for housenumber names 
The search still included a lookup of housenumbers in children which is
wrong.

75139961a3 use constant expressions to select partial indexes in reverse 
When expressions are generated with SQLAlchemy, any constants are
replaced with bind parameters. The bind parameters become parameters of
prepared statements. The result is that the query planner tends to
oversee that the partial indexes can be used.

e67355ab0e make get_addressdata calls cachable 
VALUEs() is not a cachable construct in SQLAlchemy, so use arrays
instead. Also add a special case for single results, the usual result
for reverse queries.

645ea5a057 use information from tokenizer to determine street vs. place address 
So far the SQL logic used the information from the address field
to determine if an address is attached to a street or place.
This changes the logic to use the information provided in the
token_info. This allows sanitizers to enforce a certain parenting
without changing the visible address information.
