increase splitting for large geometries
When computing the address parts for a geometry, we need to do
a ST_Relates lookup in the location_area_large_* tables. This is
potentially very expensive for geometries with many vertices.
There is already a funtion for splitting large areas to reduce the
impact. This commit reduces the minimum area of a split, effectively
increasing the number of splits.
The effect on database size is minimal (around 3% increase), while
the indexing speed for streets increases by a good 60%.

make sure that addr:* tags can always be searched for
Always add contents of addr:* tags into address part of the search
table, even when there is no corresponding other name. This keeps
search tolerant to the kind of tagging where parts show up in the
address that have no corresponding object in the database or where
it is only an unaddressable object.

switch indexind to address rank
A place needs all lower address rank object indexed to make up
the address. The search rank no longer ensures that as it can have
a different ordering than the address rank.
This switches indexing rank order to address ranks. Non-address
objects (with address rank 0) are indexed together with POIs.

remove traffic signs from full styles
Traffic signs rarely have name and are therefore mostly not
searchable. Remove them completely. Allow street lamps only when
they have a name. Removes about 2M object from a planet instance.

remove linked_place from extratags when updating
Before updating an admin boundary we need to make sure that any
artificially generated 'linked_place' entry is removed from the
extratags column. This ensures that the place designation does
not linger when a linked place disappears and that it is updated
when the linking changes.

also take place tags into account for address rank
An admin boundary might have a place tag but no matching place node.
We still should use the place value as indicator for the address
rank in this case.

preserve admin level hierarchy between admin boundaries
When the address rank of an admin boundary is changed because
of an attached place type, it may happen that the admin_level
hierarchy gets inversed. Avoid that by adjusting the address
rank if an inversion is detected.

implicitly connect to database during setup
Make access to the DB object a function, so that the connection
can be opened implicitly when the object is accessed for the first
time. This way we no longer need to check beforehand if a specific
function of the setup needs DB access or not.
Also move the check for the module to the relevant sub step.

change place node expansion for large area table
So far we've used a buffer around a place node to define its
potential address reach. This had two problems: the buffer was
so large that addresses often contain false positives and the
buffer is really distorted when getting closer to the poles.
Change the buffer here to draw a bounndig box at a certain
distance in meter. This means that we always use the same
box everywhere on the planet and can make the extent much
smaller. Using a box has the advantage that it is much faster
to figure out if a point is within the box.
